Geography of Croatia

The geography of Croatia is defined by its location—it is described as located at the crossroads of Central Europe and Southeast Europe, a part of the Balkans and Southern Europe. Croatia's territory covers 56594 km2, making it the 127th largest country in the world. Bordered by Slovenia in the northwest, Hungary in the northeast, Bosnia and Herzegovina and Serbia in the east, Montenegro in the southeast and the Adriatic Sea in the south, it lies mostly between latitudes 42° and 47° N and longitudes 13° and 20° E. Croatia's territorial waters encompass 18981 km2 in a 12 nmi wide zone, and its internal waters located within the baseline cover an additional 12498 km2.

The Pannonian Plain and the Dinaric Alps, along with the Adriatic Basin, represent major geomorphological parts of Croatia. Lowlands make up the bulk of Croatia, with elevations of less than 200 m above sea level recorded in 53.42% of the country. Most of the lowlands are found in the northern regions, especially in Slavonia, itself a part of the Pannonian Basin plain. The plains are interspersed with horst and graben structures, believed to have broken the Pliocene Pannonian Sea's surface as islands. The greatest concentration of ground at relatively high elevations is found in the Lika and Gorski Kotar areas in the Dinaric Alps, but high areas are found in all regions of Croatia to some extent. The Dinaric Alps contain the highest mountain in Croatia—1831 m Dinara—as well as all other mountains in Croatia higher than 1500 m. Croatia's Adriatic Sea mainland coast is 1777.3 km long, while its 1,246 islands and islets encompass a further 4058 km of coastline—the most indented coastline in the Mediterranean. Karst topography makes up about half of Croatia and is especially prominent in the Dinaric Alps, as well as throughout the coastal areas and the islands.

62% of Croatia's territory is encompassed by the Adriatic Sea. The area includes the largest rivers flowing in the country: the Danube, Sava, Drava, Mur and Kupa. The remainder belongs to the Adriatic Sea drainage basin, where the largest river by far is the Neretva. Most of Croatia has a moderately warm and rainy continental climate as defined by the Köppen climate classification. The mean monthly temperature ranges between -3 °C and 18 °C. Croatia has a number of ecoregions because of its climate and geomorphology, and the country is consequently among the most biodiverse in Europe. There are four types of biogeographical regions in Croatia: Mediterranean along the coast and in its immediate hinterland; Alpine in the elevated Lika and Gorski Kotar; Pannonian along the Drava and Danube; and Continental in the remaining areas. There are 444 protected natural areas in Croatia, encompassing 8.5% of the country; there are about 37,000 known species in Croatia, and the total number of species is estimated to be between 50,000 and 100,000.

The permanent population of Croatia by the 2011 census reached 4.29 million. The population density was 75.8 inhabitants per square kilometre, and the overall life expectancy in Croatia at birth was 75.7 years. The country is inhabited mostly by Croats (89.6%), while minorities include Serbs (4.5%), and 21 other ethnicities (less than 1% each) recognised by the constitution. Since the counties were re-established in 1992, Croatia is divided into 20 counties and the capital city of Zagreb. The counties subdivide into 127 cities and 429 municipalities. The average urbanisation rate in Croatia stands at 56%, with a growing urban population and shrinking rural population. The largest city and the nation's capital is Zagreb, with an urban population of 797,952 in the city itself and a metropolitan area population of 978,161. The populations of Split and Rijeka exceed 100,000, and five more cities in Croatia have populations over 50,000.

Area and borders
Croatia's territory covers 56594 km2, making it the 127th largest country in the world. The physical geography of Croatia is defined by its location—it is described as a part of Southeast Europe. Croatia borders Bosnia–Herzegovina (for 1,009.1 km), Slovenia for 667.8 km in the northwest, in the east, Hungary for 355.5 km in the north, Serbia (for 317.6 km) in the east, Montenegro (for 22.6 km) in the southeast and the Adriatic Sea in the west, south and southwest. It lies mostly between latitudes 42° and 47° N and longitudes 13° and 20° E. Part of the extreme south of Croatia is separated from the rest of the mainland by a short coastline strip around Neum belonging to Bosnia–Herzegovina. The country's shape is described as a 'horseshoe' (potkova), and it arose as a result of medieval geopolitics.

Croatia's 348 km border with Hungary was inherited from Yugoslavia. Much of the border with Hungary follows the Drava River or its former river bed; that part of the border dates from the Middle Ages. The border in Međimurje and Baranya was defined as a border between the Kingdom of Hungary and the Kingdom of Serbs, Croats, and Slovenes, later renamed the Kingdom of Yugoslavia, pursuant to the Treaty of Trianon of 1920. The present outline of the 956 km border with Bosnia–Herzegovina and 19 km border with Montenegro is largely the result of the Ottoman conquest and subsequent recapture of territories in the Great Turkish War of 1667–1698 formally ending with the Treaty of Karlowitz, as well as the Fifth and Seventh Ottoman–Venetian Wars. This border had minor modifications in 1947 when all borders of the former Yugoslav constituent republics were defined by demarcation commissions implementing the AVNOJ decisions of 1943 and 1945 regarding the federal organisation of Yugoslavia. The commissions also defined Baranya and Međimurje as Croatian territories, and moreover set up the present-day 314 km border between Serbia and Croatia in Syrmia and along the Danube River between Ilok and the Drava river's mouth and further north to the Hungarian border; the Ilok/Drava section matched the border between the Kingdom of Croatia-Slavonia and Bács-Bodrog County that existed until 1918 (the end of World War I). Most of the 600 km border with Slovenia was also defined by the commissions, matching the northwestern border of the Kingdom of Croatia-Slavonia, and establishing a new section of Croatian border north of the Istrian peninsula according to the ethnic composition of the territory previously belonging to the Kingdom of Italy.

Pursuant to the 1947 Treaty of Peace with Italy the islands of Cres, Lastovo and Palagruža and the cities of Zadar and Rijeka and most of Istria went to communist Yugoslavia and Croatia, while carving out the Free Territory of Trieste (FTT) as a city-state. The FTT was partitioned in 1954 as Trieste itself and the area to the north of it were placed under Italian control, and the rest under Yugoslav control. The arrangement was made permanent by the Treaty of Osimo in 1975. The former FTT's Yugoslav part was partitioned between Croatia and Slovenia, largely conforming to the area population's ethnic composition.

In the late 19th century, Austria-Hungary established a geodetic network, for which the elevation benchmark was determined by the Adriatic Sea's average level at the Sartorio pier in Trieste. This benchmark was subsequently retained by Austria, adopted by Yugoslavia, and kept by the states that emerged after its dissolution, including Croatia.

Extreme points
The geographical extreme points of Croatia are Žabnik in Međimurje County as the northernmost point, Rađevac near Ilok in Vukovar-Syrmia County as the easternmost point, Cape Lako near Bašanija in Istria County as the westernmost point and the islet of Galijula in Palagruža archipelago in Split-Dalmatia County as the southernmost point. On the mainland, Cape Oštra of the Prevlaka peninsula in Dubrovnik-Neretva County is the southernmost point.

Maritime claims

Italy and Yugoslavia defined their delineation of the continental shelf in the Adriatic Sea in 1968, with an additional agreement on the boundary in the Gulf of Trieste signed in 1975 in accordance with the Treaty of Osimo. All the successor states of former Yugoslavia accepted the agreements. Prior to Yugoslavia's break-up, Albania, Italy and Yugoslavia initially proclaimed 15 nmi territorial waters, subsequently reduced to the international-standard 12 nmi; all sides adopted baseline systems. Croatia also declared its Ecological and Fisheries Protection Zone (ZERP)—a part of its Exclusive Economic Zone—as extending to the continental shelf boundary. Croatia's territorial waters encompass 18981 km2; its internal waters located within the baseline cover an additional 12498 km2.

Maritime border disputes
Croatia and Slovenia started negotiations to define maritime borders in the Gulf of Piran in 1992 but failed to agree, resulting in a dispute. Both countries also declared their economic zones, which partially overlap. Croatia's application to become an EU member state was initially suspended pending resolution of its border disputes with Slovenia. These were eventually settled with an agreement to accept the decision of an international arbitration commission set up via the UN, enabling Croatia to progress towards EU membership. The dispute has caused no major practical problems in areas other than the EU membership negotiations progress, even before the arbitration agreement.

The maritime boundary between Bosnia–Herzegovina and Croatia was formally settled in 1999, but a few issues are still contested—the Klek peninsula and two islets in the border area. The Croatia–Montenegro maritime boundary is disputed in the Bay of Kotor, at the Prevlaka peninsula. The situation was exacerbated by the peninsula's occupation by the Yugoslav People's Army and later by the Serbian-Montenegrin army, which in turn was replaced by a United Nations observer mission that lasted until 2002. Croatia took over the area with an agreement that allowed Montenegrin presence in Croatian waters in the bay, and the dispute has become far less contentious since the independence of Montenegro in 2006.

Land border disputes
The land border disputes pertain to comparatively small strips of land. The Croatia–Slovenia border disputes are: along the Dragonja River's lower course where Slovenia claims three hamlets on the river's left bank; the Sveta Gera peak of Žumberak where exact territorial claims were never made and appear to be limited to a military barracks on the peak itself; and along the Mura River where Slovenia wants the border to be along the current river bed instead of along a former one and claims a (largely if not completely uninhabited) piece of land near Hotiza. These claims are likewise in the process of being settled by binding arbitration.

There are also land border disputes between Croatia and Serbia. The two countries presently control one bank of the present-day river each, but Croatia claims that the border line should follow the cadastral borders between the former municipalities of SR Croatia and SR Serbia along the Danube, as defined by a Yugoslav commission in 1947 (effectively following a former river bed); borders claimed by Croatia also include the Vukovar and Šarengrad islands in the Danube as its territory. There is also a border dispute with Bosnia–Herzegovina, specifically Croatia claims Unčica channel on the right bank of Una as the border at Hrvatska Kostajnica, while Bosnia and Herzegovina claims Una River course as the border there.

Geology
The geology of Croatia has some Precambrian rocks mostly covered by younger sedimentary rocks and deformed or superimposed by tectonic activity.

The country is split into two main onshore provinces, a smaller part of the Pannonian Basin and the larger Dinarides. These areas are very different.

The carbonate platform karst landscape of Croatia helped to create the weathering conditions to form bauxite, gypsum, clay, amphibolite, granite, spilite, gabbro, diabase and limestone.

Topography
Most of Croatia is lowlands, with elevations of less than 200 m above sea level recorded in 53.42% of the country. Most of the lowlands are found in the country's northern regions, especially in Slavonia, representing a part of the Pannonian Basin. Areas with elevations of 200 to 500 m above sea level encompass 25.61% of Croatia's territory, and the areas between 500 and 1000 m above sea level cover 17.11% of the country. A further 3.71% of the land is 1000 to 1500 m above sea level, and only 0.15% of Croatia's territory is elevated greater than 1500 m above sea level. The greatest concentration of ground at relatively high elevations is found in the Lika and Gorski Kotar areas in the Dinaric Alps, but such areas are found in all regions of Croatia to some extent. The Pannonian Basin and the Dinaric Alps, along with the Adriatic Basin, represent major geomorphological parts of Croatia.

Adriatic Basin

Croatia's Adriatic Sea mainland coast is 1777.3 km long, while its 1,246 islands and islets have a further 4058 km of coastline. The distance between the extreme points of Croatia's coastline is 526 km. The number of islands includes all islands, islets, and rocks of all sizes, including ones emerging only at low tide. The largest islands in the Adriatic are Cres and Krk, each covering 405.78 km2; the tallest is Brač, reaching 780 m above sea level. The islands include 47 permanently inhabited ones, the most populous among them being Krk and Korčula.

The shore is the most indented coastline in the Mediterranean. The majority of the coast is characterised by a karst topography, developed from the Adriatic Carbonate Platform. Karstification there largely began after the final raising of the Dinarides in the Oligocene and Miocene epochs, when carbonate rock was exposed to atmospheric effects such as rain; this extended to 120 m below the present sea level, exposed during the Last Glacial Maximum's sea level drop. It is estimated that some karst formations are related to earlier drops of sea level, most notably the Messinian salinity crisis. The eastern coast's largest part consists of carbonate rocks, while flysch rock is significantly represented in the Gulf of Trieste coast, on the Kvarner Gulf coast opposite Krk, and in Dalmatia north of Split. There are comparably small alluvial areas of the Adriatic coast in Croatia—most notably the Neretva river delta. Western Istria is gradually subsiding, having sunk about 1.5 m in the past 2,000 years.

In the Middle Adriatic Basin, there is evidence of Permian volcanism in the area of Komiža on the island of Vis, in addition to the volcanic islands of Jabuka and Brusnik. Earthquakes are frequent in the area around the Adriatic Sea, although most are too faint to be felt; an earthquake doing significant damage happens every few decades, with major earthquakes every few centuries.

Dinaric Alps
The Dinaric Alps are linked to a Late Jurassic to recent times fold and thrust belt, itself part of the Alpine orogeny, extending southeast from the southern Alps. The Dinaric Alps in Croatia encompass the entire Gorski Kotar and Lika regions, as well as considerable parts of Dalmatia, with their northeastern edge running from 1181 m Žumberak to the Banovina region, along the Sava River, and their westernmost landforms being 1272 m Ćićarija and 1396 m Učka mountains in Istria. The Dinaric Alps contain the highest mountain in Croatia—1831 m Dinara—as well as all other mountains in Croatia higher than 1500 m: Biokovo, Velebit, Plješivica, Velika Kapela, Risnjak, Svilaja and Snježnik.

Karst topography makes up about half of Croatia and is especially prominent in the Dinaric Alps. There are numerous caves in Croatia, 49 of which are deeper than 250 m, 14 deeper than 500 m and 3 deeper than 1000 m. The longest cave in Croatia, Kita Gaćešina, is at the same time the longest cave in the Dinaric Alps at 20656 m.

Pannonian Basin

The Pannonian Basin took shape through Miocenian thinning and subsidence of crust structures formed during the Late Paleozoic Variscan orogeny. The Paleozoic and Mesozoic structures are visible in Papuk and other Slavonian mountains. The processes also led to the formation of a stratovolcanic chain in the basin 12–17 Mya; intensified subsidence was observed until 5 Mya as well as flood basalts at about 7.5 Mya. The contemporary tectonic uplift of the Carpathian Mountains severed water flow to the Black Sea and the Pannonian Sea formed in the basin. Sediments were transported to the basin from the uplifting Carpathian and Dinaric mountains, with particularly deep fluvial sediments being deposited in the Pleistocene epoch during the Transdanubian Mountains' formation. Ultimately, up to 3000 m of sediment was deposited in the basin, and the sea eventually drained through the Iron Gate gorge.

The results are large plains in eastern Slavonia's Baranya and Syrmia regions, as well as in river valleys, especially along the Sava, Drava and Kupa. The plains are interspersed by horst and graben structures, believed to have broken the Pannonian Sea's surface as islands. The tallest among such landforms are 1059 m Ivanšćica and 1035 m Medvednica north of Zagreb—both are also at least partially in Hrvatsko Zagorje—as well as 984 m Psunj and 953 m Papuk that are the tallest among the Slavonian mountains surrounding Požega. Psunj, Papuk and adjacent Krndija consist mostly of Paleozoic rocks from 300 to 350 Mya. Požeška gora, adjacent to Psunj, consists of much more recent Neogene rocks, but there are also Upper Cretaceous sediments and igneous rocks forming the main, 30 km ridge of the hill; these represent the largest igneous landform in Croatia. A smaller piece of igneous terrain is also present on Papuk, near Voćin. The two, as well as the Moslavačka gora mountains, are possibly remnants of a volcanic arc from the same tectonic plate collision that caused the Dinaric Alps.

Hydrography

The largest part of Croatia—62% of its territory—is encompassed by the Black Sea drainage basin. The area includes the largest rivers flowing in the country: the Danube, Sava, Drava, Mura and Kupa. The rest belongs to the Adriatic Sea drainage basin, where the largest river by far is the Neretva. The longest rivers in Croatia are the 562 km Sava, 505 km Drava, 296 km Kupa and a 188 km section of the Danube. The longest rivers emptying into the Adriatic Sea are the 101 km Cetina and an only 20 km section of the Neretva.

The largest lakes in Croatia are 30.7 km2 Lake Vrana located in the northern Dalmatia, 17.1 km2 Lake Dubrava near Varaždin, 13.0 km2 Peruća Lake (reservoir) on the Cetina River, 11.1 km2 Lake Prokljan near Skradin and 10.1 km2 Lake Varaždin reservoir through which the Drava River flows near Varaždin. Croatia's most famous lakes are the Plitvice lakes, a system of 16 lakes with waterfalls connecting them over dolomite and limestone cascades. The lakes are renowned for their distinctive colours, ranging from turquoise to mint green, grey or blue. Croatia has a remarkable wealth in terms of wetlands. Four of those are included in the Ramsar list of internationally important wetlands: Lonjsko Polje along the Sava and Lonja rivers near Sisak, Kopački Rit at the confluence of the Drava and Danube, the Neretva Delta and Crna Mlaka near Jastrebarsko.

Average annual precipitation and evaporation rates are 1162 mm and 700 mm, respectively. Taking into consideration the overall water balance, the total Croatian water resources amount to 25163 m3 per year per capita, including 5877 m3 per year per capita from sources inside Croatia.

Climate
Most of Croatia has a moderately warm and rainy oceanic climate (Cfb) as defined by the Köppen climate classification. Mean monthly temperatures range between -3 °C (in January) and 18 °C (in July). The coldest parts of the country are Lika and Gorski Kotar where a snowy forested climate is found at elevations above 1200 m. The warmest areas of Croatia are at the Adriatic coast and especially in its immediate hinterland, which are characterised by a Mediterranean climate since temperatures are moderated by the sea. Consequently, temperature peaks are more pronounced in the continental areas: the lowest temperature of -36.0 °C was recorded on 4 February 1929 in Gospić, and the highest temperature of 42.8 °C was recorded on 5 August 1981 in Ploče.

The mean annual precipitation is 600 to 3500 mm depending on the geographic region and prevailing climate type. The least precipitation is recorded in the outer islands (Vis, Lastovo, Biševo, and Svetac) and in the eastern parts of Slavonia; however, in the latter case it is mostly during the growing season. The most precipitation is observed on the Dinara mountain range and in Gorski Kotar, where some of the highest annual precipitation totals in Europe occur.

The prevailing winds in the interior are light to moderate northeast or southwest; in the coastal area, the prevailing winds are determined by local area features. Higher wind velocities are more often recorded in cooler months along the coast, generally as cool northeasterly buras or, less frequently, as warm southerly jugos. The sunniest parts of the country are the outer islands, Hvar and Korčula, where more than 2,700 hours of sunshine are recorded per year, followed by the southern Adriatic Sea area in general, northern Adriatic coast, and Slavonia, all with more than 2,000 hours of sunshine per year.

Biodiversity

Croatia can be subdivided between a number of ecoregions because of its climate and geomorphology, and the country is consequently one of the richest in Europe in terms of biodiversity. There are four types of biogeographical regions in Croatia: Mediterranean along the coast and in its immediate hinterland, Alpine in most of Lika and Gorski Kotar, Pannonian along the Drava and Danube, and continental in the remaining areas. Among the most significant are karst habitats; these include submerged karst, such as Zrmanja and Krka canyons and tufa barriers, as well as underground habitats. The karst geology has produced approximately 7,000 caves and pits, many of which are inhabited by troglobitic (exclusively cave-dwelling) animals such as the olm, a cave salamander and the only European troglobitic vertebrate. Forests are also significant in the country, as they cover 26487.6 km2 representing 46.8% of Croatia's land surface. The other habitat types include wetlands, grasslands, bogs, fens, scrub habitats, coastal and marine habitats. In terms of phytogeography, Croatia is part of the Boreal Kingdom; specifically, it is part of the Illyrian and Central European provinces of the Circumboreal Region and the Adriatic province of the Mediterranean Region. The World Wide Fund for Nature divides land in Croatia into three ecoregions—Pannonian mixed forests, Dinaric Mountains mixed forests and Illyrian deciduous forests. Biomes in Croatia include temperate broadleaf/mixed forest and Mediterranean forests, woodlands and scrub; all are in the Palearctic realm.

Croatia has 38,226 known taxa, 2.8% of which are endemic; the actual number (including undiscovered species) is estimated to be between 50,000 and 100,000. The estimate is supported by nearly 400 new taxa of invertebrates discovered in Croatia in 2000–2005 alone. There are more than a thousand endemic species, especially in the Velebit and Biokovo mountains, Adriatic islands and karst rivers. Legislation protects 1,131 species. Indigenous cultivars of plants and breeds of domesticated animals are also numerous; they include five breeds of horses, five breeds of cattle, eight breeds of sheep, two breeds of pigs and a poultry breed. Even the indigenous breeds include nine endangered or critically endangered ones.

There are 444 Croatian protected areas, encompassing 8.5% of the country. These include 8 national parks, 2 strict reserves and 11 nature parks, accounting for 78% of the total protected area. The most famous protected area and the oldest national park in Croatia is the Plitvice Lakes National Park, a UNESCO World Heritage Site. Velebit Nature Park is a part of the UNESCO Man and the Biosphere Programme. The strict and special reserves, as well as the national and nature parks, are managed and protected by the central government, while other protected areas are managed by counties. In 2005, the National Ecological Network was set up as the first step in preparation for EU membership and joining the Natura 2000 network.

Habitat destruction represents a threat to biodiversity in Croatia, as developed and agricultural land is expanded into previous natural habitats, while habitat fragmentation occurs as roads are created or expanded. A further threat to biodiversity is the introduction of invasive species, with Caulerpa racemosa and C. taxifolia identified as especially problematic ones. The invasive algae are monitored and regularly removed to protect the benthic habitat. Agricultural monocultures have also been identified as a threat to biodiversity.

Ecology
The ecological footprint of Croatia's population and industry varies significantly between the country's regions since 50% of the population resides in 26.8% of the nation's territory, with a particularly high impact made by the city of Zagreb and Zagreb County areas—their combined area comprises 6.6% of Croatia's territory while encompassing 25% of the population. The ecological footprint is most notably from the increased development of settlements and the sea coast leading to habitat fragmentation. Between 1998 and 2008, the greatest changes of land use pertained to artificially developed areas, but the scale of development is negligible compared to EU member states.

The Croatian Environment Agency (CEA), a public institution established by the Government of Croatia to collect and analyse information on the environment, has identified further ecological problems as well as various degrees of progress in terms of curbing their environmental impact. These problems include inadequate legal landfills as well as the presence of illegal landfills; between 2005 and 2008, 62 authorised and 423 illegal landfills were rehabilitated. In the same period, the number of issued waste management licences doubled, while the annual municipal solid waste volume increased by 23%, reaching 403 kg per capita. The processes of soil acidification and organic matter degradation are present throughout Croatia, with increasing soil salinity levels in the Neretva river plain and spreading areas of alkali soil in Slavonia.

Croatian air pollution levels reflect the drop in industrial production recorded in 1991 at the onset of the Croatian War of Independence—pre-war emission levels were only reached in 1997. The use of desulfurised fuels has led to a 25% reduction of sulphur dioxide emissions between 1997 and 2004, and a further 7.2% drop by 2007. The rise in NOx emissions halted in 2007 and reversed in 2008. The use of unleaded petrol reduced emissions of lead into the atmosphere by 91.5% between 1997 and 2004. Air quality measurements indicate that the air in rural areas is essentially clean, and in urban centres it generally complies with legal requirements. The most significant sources of greenhouse gas (GHG) emissions in Croatia are energy production (72%), industry (13%) and agriculture (11%). The average annual increase of GHG emissions is 3%, remaining within the Kyoto Protocol limits. Between 1990 and 2007, the use of ozone depleting substances was reduced by 92%; their use is expected to be abolished by 2015.

Even though Croatia has sufficient water resources at its disposal, these are not uniformly distributed and public water supply network losses remain high—estimated at 44%. Between 2004 and 2008, the number of stations monitoring surface water pollution increased by 20%; the CEA reported 476 cases of water pollution in this period. At the same time organic waste pollution levels decreased slightly, which is attributed to the completion of new sewage treatment plants; their number increased 20%, reaching a total of 101. Nearly all of Croatia's groundwater aquifers are top quality, unlike the available surface water; the latter's quality varies in terms of biochemical oxygen demand and bacteriological water analysis results. As of 2008, 80% of the Croatian population are served by the public water supply system, but only 44% of the population have access to the public sewerage network, with septic systems in use. Adriatic Sea water quality monitoring between 2004 and 2008 indicated very good, oligotrophic conditions along most of the coast, while areas of increased eutrophication were identified in the Bay of Bakar, the Bay of Kaštela, the Port of Šibenik and near Ploče; other areas of localised pollution were identified near the larger coastal cities. In the period between 2004 and 2008, the CEA identified 283 cases of marine pollution (including 128 from vessels), which was a drop of 15% relative to the period encompassed by the previous report, 1997 to August 2005.

Land use
As of 2006, 46.8% of Croatia was occupied by 26487.6 km2 of forest and shrub, while a further 22841 km2 or 40.4% of the land was used for diverse agricultural uses including 4389.1 km2, or 7.8% of the total, for permanent crops. Bush and grass cover was present on 4742.1 km2 or 8.4% of the territory, inland waters took up 539.3 km2 or 1.0% and marshes covered 200 km2 or 0.4% of the country. Artificial surfaces (primarily consisting of urban areas, roads, non-agricultural vegetation, sports areas and other recreational facilities) took up 1774.5 km2 or 3.1% of the country's area. The greatest impetus for land use changes is the expansion of settlements and road construction.

Because of the Croatian War of Independence, there are numerous leftover minefields in Croatia, largely tracing former front lines. As of 2006, suspected minefields covered 954.5 km2. As of 2012, 62% of the remaining minefields are situated in forests, 26% of them are found in agricultural land, and 12% are found in other land; it is expected that mine clearance will be complete by 2019.

Regions
Croatia is traditionally divided into numerous, often overlapping geographic regions, whose borders are not always clearly defined. The largest and most readily recognisable ones throughout the country are Central Croatia (also described as the Zagreb macro-region), Eastern Croatia (largely corresponding with Slavonia), and Mountainous Croatia (Lika and Gorski Kotar; to the west of Central Croatia). These three comprise the inland or continental part of Croatia. Coastal Croatia consists of a further two regions: Dalmatia or the southern littoral, between the general area of the city of Zadar and the southernmost tip of the country; and the northern littoral located north of Dalmatia, encompassing the Croatian Littoral and Istria. The geographical regions generally do not conform to county boundaries or other administrative divisions, and all of them encompass further, more specific, geographic regions.

Demographics
The demographic features of the Croatian population are known through censuses, normally conducted in ten-year intervals and analysed by various statistical bureaus since the 1850s. The Croatian Bureau of Statistics has performed this task since the 1990s. The latest census in Croatia was performed in April 2011. The permanent population of Croatia at the 2011 census had reached 4.29 million. The population density was 75.8 inhabitants per square kilometre, and the overall life expectancy in Croatia at birth is 75.7 years. The population rose steadily (with the exception of censuses taken following the two world wars) from 2.1 million in 1857 until 1991, when it peaked at 4.7 million. Since 1991, Croatia's death rate has continuously exceeded its birth rate; the natural growth rate of the population is thus currently negative. Croatia is currently in the demographic transition's fourth or fifth stage. In terms of age structure, the population is dominated by the 15‑ to 64‑year‑old segment. The median age of the population is 41.4, and the gender ratio of the total population is 0.93 males per 1 female.

Croatia is inhabited mostly by Croats (89.6%), while minorities include Serbs (4.5%) and 21 other ethnicities (less than 1% each) recognised by the Constitution of Croatia. The demographic history of Croatia is marked by significant migrations, including: the Croats' arrival in the area; the growth of the Hungarian and German speaking population after the personal union of Croatia and Hungary; joining of the Habsburg Empire; migrations set off by the Ottoman conquests;  and the growth of the Italian-speaking population in Istria and Dalmatia during the Venetian rule there. After Austria-Hungary's collapse, the Hungarian population declined, while the German-speaking population was forced out or fled during the last part of and after World War II, and a similar fate was suffered by the Italian population. The late 19th century and the 20th century were marked by large scale economic migrations abroad. The 1940s and the 1950s in Yugoslavia were marked by internal migrations in Yugoslavia, as well as by urbanisation. The most recent significant migrations came as a result of the Croatian War of Independence when hundreds of thousands were displaced.

The Croatian language is Croatia's official language, but the languages of constitutionally-recognised minorities are officially used in some local government units. Croatian is the native language identified by 96% of the population. A 2009 survey revealed that 78% of Croatians claim knowledge of at least one foreign language—most often English. The largest religions of Croatia are Roman Catholicism (86.3%), Orthodox Christianity (4.4%) and Islam (1.5%). Literacy in Croatia stands at 98.1%. The proportion of the population aged 15 and over attaining academic degrees has grown rapidly since 2001, doubling and reaching 16.7% by 2008. An estimated 4.5% of GDP is spent for education. Primary and secondary education are available in Croatian and in the languages of recognised minorities. Croatia has a universal health care system and in 2010, the nation spent 6.9% of its GDP on healthcare. The net monthly income in September 2011 averaged 5,397 kuna (c. €729). The most significant sources of employment in 2008 were wholesale and retail trade, the manufacturing industry and construction. In October 2011, the unemployment rate was 17.4%. Croatia's median equivalent household income tops the average Purchasing Power Standard of the ten countries which joined the EU in 2004, while trailing the EU average. The 2011 census recorded a total of 1.5 million private households; most owned their own housing.

Political geography
Croatia was first subdivided into counties in the Middle Ages. The divisions changed over time to reflect losses of territory to Ottoman conquest and subsequent liberation of the same territory, in addition to changes in the political status of Dalmatia, Dubrovnik and Istria. The traditional division of the country into counties was abolished in the 1920s, when the Kingdom of Serbs, Croats and Slovenes and the subsequent Kingdom of Yugoslavia introduced oblasts and banovinas respectively. Communist-ruled Croatia, as a constituent part of post-WWII Yugoslavia, abolished earlier divisions and introduced (mostly rural) municipalities, subdividing Croatia into approximately one hundred municipalities. Counties were reintroduced in 1992 by legislation, significantly altered in terms of territory relative to the pre-1920s subdivisions—for instance, in 1918 the Transleithanian part of Croatia was divided into eight counties with their seats in Bjelovar, Gospić, Ogulin, Požega, Vukovar, Varaždin, Osijek and Zagreb, while the 1992 legislation established 14 counties in the same territory. Međimurje County was established in the eponymous region acquired through the 1920 Treaty of Trianon. (The 1990 Croatian Constitution provided for a Chamber of the Counties as part of the government, and for counties themselves without specifying their names or number. However, the counties were not actually re-established until 1992, and the first Chamber of the Counties was elected in 1993.)

Since the counties were re-established in 1992, Croatia has been divided into 20 counties and the capital city of Zagreb, the latter having the authority and legal status of a county and a city at the same time (Zagreb County outside the city is administratively separate as of 1997). The county borders have changed in some instances since (for reasons such as historical ties and requests by cities), with the latest revision taking place in 2006. The counties subdivide into 127 cities and 429 municipalities.

The EU Nomenclature of Territorial Units for Statistics (NUTS) division of Croatia is performed in several tiers. NUTS 1 level places the entire country in a single unit, while there are three NUTS 2 regions; these are Central and Eastern (Pannonian) Croatia, Northwest Croatia and Adriatic Croatia. The last encompasses all counties along the Adriatic coast. Northwest Croatia includes the city of Zagreb and Krapina-Zagorje, Varaždin, Koprivnica-Križevci, Međimurje and Zagreb counties, and the Central and Eastern (Pannonian) Croatia includes the remaining areas—Bjelovar-Bilogora, Virovitica-Podravina, Požega-Slavonia, Brod-Posavina, Osijek-Baranja, Vukovar-Syrmia, Karlovac and Sisak-Moslavina counties. Individual counties and the city of Zagreb represent NUTS 3 level subdivision units in Croatia. The NUTS Local administrative unit divisions are two-tiered. The LAU 1 divisions match the counties and the city of Zagreb—in effect making these the same as NUTS 3 units—while the LAU 2 subdivisions correspond to the cities and municipalities of Croatia.

Urbanisation
The average urbanisation rate in Croatia stands at 56%, with a growing urban population and shrinking rural population. The largest city and the nation's capital is Zagreb, with an urban population of 686,568 in the city itself. Zagreb's metropolitan area encompasses 341 additional settlements and, by the year 2001, the population of the area had reached 978,161; approximately 60% of Zagreb County's residents live in Zagreb's metropolitan area, as does about 41% of Croatia's urban population. The cities of Split and Rijeka are the largest settlements on the Croatian Adriatic coast, with each city's population being over 100,000. There are four other Croatian cities exceeding 50,000 people: Osijek, Zadar, Pula and Slavonski Brod; the Zagreb district of Sesvete, which has the status of a standalone settlement but not a city, also has such a large population. A further eleven cities are populated by more than 20,000.

Demographics of Croatia

The demographic characteristics of the population of Croatia are known through censuses, normally conducted in ten-year intervals and analysed by various statistical bureaus since the 1850s. The Croatian Bureau of Statistics has performed this task since the 1990s. The latest census in Croatia was performed in autumn of 2021. According to final results published on 22 September 2022 the permanent population of Croatia at the 2021 census (31st Aug) had reached 3.87 million. The population density is 68.7 inhabitants per square kilometre, and the overall life expectancy in Croatia at birth was 78,2 years in 2018. The population rose steadily (with the exception of censuses taken following the two world wars) from 2.1 million in 1857 until 1991, when it peaked at 4.7 million. Since 1991, Croatia's death rate has continuously exceeded its birth rate; the natural growth rate of the population is negative. Croatia is in the fourth (or fifth) stage of the demographic transition. In terms of age structure, the population is dominated by the 15 to 64 year‑old segment. The median age of the population is 43.4, and the gender ratio of the total population is 0.93 males per 1 female.

Croatia is inhabited mostly by Croats (91.63%), while minorities include Serbs (3.2%), and 21 other ethnicities (less than 1% each). The demographic history of Croatia is marked by significant migrations, including the arrival of the Croats in the area growth of Hungarian and German-speaking population since the union of Croatia and Hungary, and joining of the Habsburg Empire, migrations set off by Ottoman conquests and growth of Italian speaking population in Istria and in Dalmatia during Venetian rule there. After the collapse of Austria-Hungary, the Hungarian population declined, while the German-speaking population was forced or compelled to leave after World War II and similar fate was suffered by the Italian population. Late 19th century and the 20th century were marked by large scale economic migrations abroad. The 1940s and the 1950s in Yugoslavia were marked by internal migrations in Yugoslavia, as well as by urbanisation. Recently, significant migrations came as a result of the Croatian War of Independence when hundreds of thousands were displaced, while the 2010s brought a new wave of emigration which strengthened after Croatia's accession to the EU in 2013.

Croatian is the official language, but minority languages are officially used in some local government units. Croatian is declared as the native language by 95.60% of the population. A 2009 survey revealed that 78% of Croatians claim knowledge of at least one foreign language—most often English. The main religions of Croatia are Roman Catholic (86.28%), Eastern Orthodoxy (4.44%) and Islam (1.47%). Literacy in Croatia stands at 98.1%. The proportion of the population aged 15 and over attaining academic degrees grew rapidly since 2001, doubling and reaching 16.7% by 2008. An estimated 4.5% of the GDP is spent for education. Primary and secondary education are available in Croatian and in languages of recognised minorities. Croatia has a universal health care system and in 2010, the nation spent 6.9% of its GDP on healthcare. Net monthly income in August 2023 averaged 1,163 euro. The most significant sources of employment in 2023 were manufacturing industry, wholesale and retail trade and construction. In August 2023, the unemployment rate was 6.9%. Croatia's median equivalent household income tops average Purchasing Power Standard of the ten countries which joined the EU in 2004, while trailing the EU average. 2011 census recorded a total of 1.5 million private households, which predominantly owned their own housing. The average urbanisation rate in Croatia stands at 56%, with an augmentation of the urban population and a reduction of the rural population.

Population

With a population of 3,871,833 in 2021, Croatia ranks 128th in the world by population. Its population density is 75.8 inhabitants per square kilometre. The overall life expectancy in Croatia at birth is 78 years.

The total fertility rate of 1.50 children per mother is one of the lowest in the world. Since 1991, Croatia's death rate has nearly continuously exceeded its birth rate. The Croatian Bureau of Statistics forecast that the population may even shrink to 3.1 million by 2051, depending on the actual birth rate and the level of net migration. The population of Croatia rose steadily from 2.1 million in 1857 until 1991, when it peaked at 4.7 million, with the exception of censuses taken in 1921 and 1948, i.e. following two world wars. The natural growth rate of the population is negative. Croatia started advancing from the first stage of the demographic transition in the late 18th and early 19th centuries (depending on where in Croatia is being discussed). Croatia is in the fourth or fifth stage of the demographic transition.

An explanation for the population decrease in the 1990s is the Croatian War of Independence. During the war, large sections of the population were displaced and emigration increased. In 1991, in predominantly Serb areas, more than 400,000 Croats and other non-Serbs were either removed from their homes by the Croatian Serb forces or fled the violence. In 1995, during the final days of the war, more than 120,000 and perhaps as many as 200,000 Serbs fled the country before the arrival of Croatian forces during Operation Storm. Within a decade following the end of the war, only 117,000 Serb refugees returned out of the 300,000 displaced during the entire war. According to 2001 Croatian census there were 201,631 Serbs in Croatia, compared to the census from 1991 when the number was 581,663. Most of Croatia's remaining Serbs never lived in areas occupied in the Croatian War of Independence. Serbs have been only partially re-settled in the regions they previously inhabited, while some of the settlements previously inhabited by Serbs were settled by Croat refugees from Bosnia and Herzegovina, mostly from Republika Srpska.

In 2014, there were 39,566 live births in Croatia, comprising 20,374 male and 19,192 female children. Virtually all of those were performed in medical facilities; only 19 births occurred elsewhere. Out of the total number, 32,677 children were born in wedlock or within 300 days after the end of the marriage, and the average age of mothers at the birth of their first child was 28.4 years. General fertility rate, i.e. number of births per 1,000 women aged 15–49 is 42.9, with the age specific rate peaking at 101.0 per million for women aged 25–29. In 2009, 52,414 persons died in Croatia, 48.5% of whom died in medical facilities and 90.0% of whom were receiving medical treatment at the time. Cardiovascular disease and cancer were the primary causes of death in the country, with 26,235 and 13,280 deaths respectively. In the same year, there were 2,986 violent deaths, including 2,121 due to accidents. The latter figure includes 616 deaths in traffic accidents. In 2014, the birth rate was 9.3 per mille, exceeded by the mortality rate of 12.0 per mille. The infant mortality rate was 5.0 per mille in 2014. In terms of age structure, the population of Croatia is dominated by the 15–64 year older segment (68.1%), while the size of the population younger than 15 and older than 64 is relatively small (15.1% and 16.9% respectively). The median age of the population is 41.4. The sex ratio of the population is 1.06 males per 1 female at birth and up to 14 years of age, and 0.99 males per 1 female between the ages of 15 and 64. But at ages over 64 the ratio is 0.64 males per 1 female. The ratio for the total population is 0.93 males per 1 female.

In contrast to the shrinking native population, since the late 1990s there has been a positive net migration into Croatia, reaching a level of more than 7,000 net immigrants in 2006. In accordance with its immigration policy, Croatia is also trying to entice emigrants to return. Croatian citizenship is acquired in a multitude of ways, based on origin, place of birth, naturalization and international treaties. In recent years, the Croatian government has been pressured each year to add 40% to work permit quotas for foreign workers.

There were 8,468 immigrants to Croatia in 2009, more than half of them (57.5%) coming from Bosnia and Herzegovina, a sharp decline from the previous year's 14,541. In the same year, there were 9,940 emigrants from the country, 44.8% of them leaving to Serbia. The number of emigrants represents a substantial increase compared to the figure of 7,488 recorded in 2008. In 2009, the net migration to and from abroad peaked in the Sisak-Moslavina County (−1,093 persons) and the city of Zagreb (+830 persons).

In 2009, a total of 22,382 marriages were performed in Croatia as well as 5,076 divorces. The 2001 census recorded 1.47 million households in the country.

Census data
The first modern population census in the country was conducted in 1857, and 15 more have been performed since then. Since 1961 the censuses are conducted in regular ten-year intervals, with the latest one in 2011. The first institution set up in the country specifically for the purposes of maintaining population statistics was the State Statistical Office, founded in 1875. Since its founding, the office changed its name and structure several times and was alternately subordinated to other institutions and independent, until the most recent changes in 1992, when the institution became the Croatian Bureau of Statistics. The 2011 census was performed on 1–28 April 2011, recording situation as of 31 March 2011. The first census results, containing the number of the population by settlement, were published on 29 June 2011, and the final comprehensive set of data was published in December 2012. The 2011 census and processing of the data gathered by the census was expected to cost 171.9 million kuna (23.3 million euro). The 2011 census was performed using new methodology: the permanent population was determined as the enumerated population who lived in the census area for at least 12 months prior to the census, or plans to live in the same area for at least 12 months after the census. This method was also retroactively applied to the 2001 census data.

Ethnic groups
Croatia is inhabited mostly by Croats (91.63%), while minority groups include: Serbs (3.2%), Bosniaks, Hungarians, Italians, Albanians, Slovenes, Germans, Czechs, Roma and others (less than 1% each). The Constitution of the Republic of Croatia explicitly identifies 22 minorities. Those are Serbs, Czechs, Slovaks, Italians, Istro-Romanians ("Vlachs"), Hungarians, Jews, Germans, Austrians, Ukrainians, Romanians, Ruthenians, Macedonians, Bosniaks, Slovenes, Montenegrins, Russians, Bulgarians, Poles, Roma, Turks and Albanians.

Significant migrations
The demographic history of Croatia is characterised by significant migrations, starting with the arrival of the Croats in the area. According to the work De Administrando Imperio written by the 10th-century Byzantine Emperor Constantine VII, the Croats arrived in the area of modern-day Croatia in the early 7th century. However, that claim is disputed, and competing hypotheses date the event between the 6th and the 9th centuries. Following the establishment of a personal union of Croatia and Hungary in 1102, and the joining of the Habsburg Empire in 1527, the Hungarian and German-speaking population of Croatia began gradually increasing in number. The processes of Magyarization and Germanization varied in intensity but persisted to the 20th century. The Ottoman conquests initiated a westward migration of parts of the Croatian population; the Burgenland Croats are direct descendants of some of those settlers. To replace the fleeing Croats the Habsburgs called on the Orthodox populations of Bosnia and Serbia to provide military service in the Croatian Military Frontier. Serb migration into this region peaked during the Great Serb Migrations of 1690 and 1737–39. Similarly, Venetian Republic rule in Istria and in Dalmatia, following the Fifth and the Seventh Ottoman–Venetian Wars ushered gradual growth of Italian speaking population in those areas. Following the collapse of Austria-Hungary in 1918, the Hungarian population declined, especially in the areas north of the Drava river, where they represented the majority before World War I.

The period between 1890 and World War I was marked by large economic emigration from Croatia to the United States, and particularly to the areas of Pittsburgh, Pennsylvania, Cleveland, Ohio, and Chicago, Illinois. Besides the United States, the main destination of the migrants was South America, especially Argentina, Chile, Bolivia and Peru. It is estimated that 500,000 people left Croatia during this period. After World War I, the main focus of emigration shifted to Canada, where about 15,000 people settled before the onset of World War II. During World War II and in the period immediately following the war, there were further significant demographic changes as the German-speaking population, the Volksdeutsche, were either forced or otherwise compelled to leave—reducing their number from the prewar German population of Yugoslavia of 500,000, living in parts of present-day Croatia and Serbia, to the figure of 62,000 recorded in the 1953 census. A similar fate was suffered by the Italian population in Yugoslavia populating parts of present-day Croatia and Slovenia, as 350,000 left for Italy. The 1940s and the 1950s in Yugoslavia were marked by colonisation of settlements where the displaced Germans used to live by people from the mountainous parts of Bosnia and Herzegovina, Serbia and Montenegro, and migrations to larger cities spurred on by the development of industry. In the 1960s and 1970s, another wave of economic migrants left Croatia. They largely moved to Canada, Australia, New Zealand and Western Europe. During this period, 65,000 people left for Canada, and by the mid-1970s there were 150,000 Croats who moved to Australia. Particularly large European emigrant communities of Croats exist in Germany, Austria and Switzerland, which largely stem from the 1960s and 1970s migrations.

A series of significant migrations came as a result of the 1991–1995 Croatian War of Independence. In 1991, more than 400,000 Croats and other non-Serbs were displaced by the Croatian Serb forces or fled the violence in areas with significant Serb populations. During the final days of the war, in 1995, between 120,000 and 200,000 Serbs fled the country following the Operation Storm. Ten years after the war, only a small portion of Serb refugees returned out of the 400,000 displaced during the entire war. Most of the Serbs in Croatia who remained never lived in areas occupied during the Croatian War of Independence. Serbs have been only partially re-settled in the regions they previously inhabited; some of these areas were later settled by Croat refugees from Bosnia and Herzegovina.

Significant migrations have been happening after the accession of Croatia to the European Union, with a persistent growth since 2013, and the population leaving is largely younger and more educated.

Demographic losses in the 20th century wars and pandemics
In addition to demographic losses through significant migrations, the population of Croatia suffered significant losses due to wars and epidemics. In the 20th century alone, there were several such events. The first was World War I, when the loss of the population of Croatia amounted to an estimated 190,000 persons, or about 5.5% of the total population recorded by the 1910 census. The 1918 flu pandemic started to take its toll in Croatia in July 1918, with peaks of the disease occurring in October and November. Available data is scarce, but it is estimated that the pandemic caused at least 15,000–20,000 deaths. Around 295,000 people were killed on the territory of present-day Croatia during World War II, according to the demographer Bogoljub Kočović. The demise of the armed forces of the Independent State of Croatia and of the civilians accompanying the troops at the end of World War II was followed by the Yugoslav death march of Nazi collaborators. A substantial number of people were executed, but the exact number is disputed. The claims range from 12,000–15,000 to as many as 80,000 killed in May 1945. Finally, approximately 20,000 were killed or went missing during the 1991–1995 Croatian War of Independence. The figure pertains only to those persons who would have been recorded by the 1991 census as living in Croatia.

Languages

Croatian is the official language of Croatia, and one of 24 official languages of the European Union since 2013. Minority languages are in official use in local government units where more than a third of the population consists of national minorities or where local legislation mandates their use. These languages are Czech, German, Hungarian, Italian, Ruthenian, Serbian, Slovene, and Slovak. Besides these, the following languages are also recognised: Albanian, Bosnian, Bulgarian, German, Hebrew, Macedonian, Montenegrin, Polish, Romanian, Romani, Russian, Rusyn, Slovenian, Turkish and Ukrainian. According to the 2021 Census, 95.25% of citizens of Croatia declared Croatian as their native language, 1.16% declared Serbian as their native language, while no other language is represented in Croatia by more than 0.5% of native speakers among the population of Croatia.

In the region of Dalmatia, each city historically spoke a variant of the Dalmatian language. It developed from Latin like all Romance languages, but became heavily influenced by Venetian and Croatian. The language fell out of use in the region by the 16th century and went extinct when the last speaker died in 1898.

Croatian replaced Latin as the official language of the Croatian government in 1847. The Croatian lect is generally viewed as one of the four standard varieties of the Shtokavian dialect of Serbo-Croatian, a South Slavic language. Croatian is written using the Latin alphabet and there are three major dialects spoken on the territory of Croatia, with the Shtokavian idiom used as the literary standard. The Chakavian and Kajkavian dialects are distinguished by their lexicon, phonology, and syntax.

From 1961 to 1991, the official language was formally designated as Serbo-Croatian or Croato-Serbian. Even during socialist rule, Croats often referred to their language as Croato-Serbian (instead of Serbo-Croatian) or as Croatian. Croatian and Serbian variants of the language were not officially recognised as separate at the time, but referred to as the "West" and "East" versions, and preferred different alphabets: the Gaj's Latin alphabet and Karadžić's Cyrillic alphabet. Croats are protective of their language from foreign influences, as the language was under constant change and threats imposed by previous rulers (i.e. Austrian German, Hungarian, Italian and Turkish words were changed and altered to "Slavic" looking/sounding ones).

A 2009 survey revealed that 78% of Croats claim knowledge of at least one foreign language. According to a survey ordered by the European commission in 2005, 49% of Croats speak English as their second language, 34% speak German, and 14% speak Italian. French and Russian are spoken by 4% each, and 2% of Croats speak Spanish. A substantial proportion of Slovenes (59%) have a certain level of knowledge of Croatian.

Religions

The main religions of Croatia are Roman Catholicism 78.97%, no religion 6.39%, other Christianity 4.84%, undeclared 3.86%, Eastern Orthodoxy 3.32%, Islam 1.32%, Protestantism 0.26%, others 1.87%. In the Eurostat Eurobarometer Poll of 2005, 67% of the population of Croatia responded that "they believe there is a God" and 7% said they do not believe "there is any sort of spirit, God, or life force", while 25% expressed a belief in "some sort of spirit or life force". In a 2009 Gallup poll, 70% answered affirmatively when asked "Is religion an important part of your daily life?" Significantly, a 2008 Gallup survey of the Balkans indicated church and religious organisations as the most trusted institutions in the country. The survey revealed that 62% of the respondents assigned "a lot" or "some" trust to those institutions, ranking them ahead of all types of governmental, international or non-governmental institutions.

Public schools allow religious education, in cooperation with religious communities that have agreements with the government, but attendance is not mandatory. The classes are organized widely in public elementary and secondary schools. In 2009, 92% of elementary school pupils and 87% of secondary school students attended the religious education classes. Public holidays in Croatia also include the religious festivals of Epiphany, Easter Monday, Feast of Corpus Christi, Assumption Day, All Saints' Day, Christmas, and St. Stephen's or Boxing Day. The religious festival public holidays are based on the Catholic liturgical year, but citizens of the Republic of Croatia who celebrate different religious holidays have the right not to work on those dates. This includes Christians who celebrate Christmas on 7 January per the Julian calendar, Muslims on the days of Eid al-Fitr and Eid al-Adha, and Jews on the days of Rosh Hashanah and Yom Kippur. Marriages performed by the religious communities having agreements with the state are officially recognized, eliminating the need to register the marriages in a registrar office.

The legal position of religious communities is defined by special legislation, specifically regarding government funding, tax benefits, and religious education in schools. Other matters are left to each religious community to negotiate separately with the government. Registration of the communities is not mandatory, but registered communities become legal persons and enjoy tax and other benefits. The law stipulates that to be eligible for registration, a religious group must have at least 500 believers and be registered as a civil association for 5 years. Religious groups based abroad must submit written permission for registration from their country of origin.

Education
Literacy in Croatia is 98.1 percent. The 2001 census reported that 15.7% of the population over the age of 14 has an incomplete elementary education, and 21.9% has only an elementary school education. 42.8% of the population over the age of 14 has a vocational education and 4.9% completed gymnasium. 4.2% of the same population received an undergraduate degree, while 7.5% received an academic degree, and 0.5% received a postgraduate or a doctoral degree. Croatia recorded a substantial growth of the population attaining academic degrees and by 2008, this population segment was estimated to encompass 16.7% of the total population of Croatians 15 and over. A worldwide study about the quality of living in different countries published by Newsweek in August 2010 ranked the Croatian education system at 22nd, a position shared with Austria. In 2004, it was estimated that 4.5% of the GDP is spent for education, while schooling expectancy was estimated to 14 years on average. Primary education in Croatia starts at the age of six or seven and consists of eight grades. In 2007 a law was passed to increase free, noncompulsory education until 18 years of age. Compulsory education consists of eight grades of elementary school. Secondary education is provided by gymnasiums and vocational schools. As of 2010, there are 2,131 elementary schools and 713 schools providing various forms of secondary education. Primary and secondary education are also available in languages of recognised minorities in Croatia, where classes are held in Czech, Hungarian, Italian, Serbian and German languages.

There are 84 elementary level and 47 secondary level music and art schools, as well as 92 schools for disabled children and youth and 74 schools for adults. Nationwide leaving exams (državna matura) were introduced for secondary education students in the 2009–2010 school year. It comprises three compulsory subjects (Croatian language, mathematics, and a foreign language) and optional subjects and is a prerequisite for a university education.

Croatia has eight public universities, the University of Zagreb, University of Split, University of Rijeka, University of Osijek, University of Zadar, University of Dubrovnik, University of Pula and Dubrovnik International University. The University of Zadar, the first university in Croatia, was founded in 1396 and remained active until 1807, when other institutions of higher education took over. It was reopened in 2002. The University of Zagreb, founded in 1669, is the oldest continuously operating university in Southeast Europe. There are also 11 polytechnics and 23 higher education institutions, of which 19 are private. In total, there are 132 institutions of higher education in Croatia, attended by more than 145 thousand students.

There are 205 companies, government or education system institutions and non-profit organizations in Croatia pursuing scientific research and the development of technology. Combined, they spent more than 3 billion kuna (400 million euro) and employed 10,191 full-time research staff in 2008. Among the scientific institutes operating in Croatia, the largest is the Ruđer Bošković Institute in Zagreb. The Croatian Academy of Sciences and Arts in Zagreb is a learned society promoting language, culture, arts and science since its inception in 1866. Scientists from Croatia include inventors and Nobel Prize winners.

Health
Croatia has a universal health care system, the roots of which can be traced back to the Hungarian-Croatian Parliament Act of 1891, providing a form of mandatory insurance for all factory workers and craftsmen. The population is covered by a basic health insurance plan provided by statute and optional insurance. In 2014, the annual compulsory healthcare related expenditures reached 21.8 billion kuna (2.9 billion euro). Healthcare expenditures comprise only 0.6% of private health insurance and public spending. In 2010, Croatia spent 6.9% of its GDP on healthcare, representing a decline from approximately 8% estimated in 2008, when 84% of healthcare spending came from public sources. According to the World Health Organization (WHO), Croatia ranks around the 50th in the world in terms of life expectancy.

There are hundreds of healthcare institutions in Croatia, including 79 hospitals and clinics with 23,967 beds. The hospitals and clinics care for more than 700 thousand patients per year and employ 5,205 medical doctors, including 3,929 specialists. There are 6,379 private practice offices, and a total of 41,271 health workers in the country. There are 63 emergency medical service units, responding to more than a million calls. The principal cause of death in 2008 was cardiovascular disease at 43.5% for men and 57.2% for women, followed by tumours, at 29.4% for men and 21.4% for women. Other significant causes of death are injuries, poisonings and other external causes (7.7% men/3.9% women), digestive system diseases (5.7% men/3.6% women), respiratory system diseases (5.1% men/3.5% women) and endocrine, nutritional and metabolic diseases (2.1% men/3.0% women). There is no other cause of disease affecting more than 3% of the population. In 2014 only 22 Croatians had been infected with HIV/AIDS and 4 had died from the disease. In 2008 it was estimated by the WHO that 27.4% of Croatians over age of 15 were smokers. According to 2003 WHO data, 22% of the Croatian adult population is obese.

Personal income, jobs and unemployment
Net monthly income in September 2011 averaged 5,397 kuna (c. 729 euro), dropping 2.1% relative to the previous month. In the same month, gross monthly income averaged 7,740 kuna (c. 1,046 euro), and it includes the net salary along with income tax, retirement pension insurance, healthcare insurance, occupational safety and health insurance and employment promotion tax. The average net monthly income grew compared to 5,311 kuna (c. 717 euro) in 2009 or 3,326 kuna (c.  449 euro) in 2000. The highest net salaries were paid in financial services sector, and in April 2011 those averaged 10,041 kuna (c. 1,356 euro), while the lowest ones, paid in the same month, were in the manufacturing and leather processing industries, averaging at 2,811 kuna (c.  380 euro). Since January 2016, the minimum wage in Croatia is 3,120 kuna before tax (c. 400 euro).

Number of employed persons recorded steady growth between 2000 and 2008 when it peaked, followed by 4% decline in 2009. That year, there were 1.499 million employed persons, with 45% of that number pertaining to women. The total number of employed persons includes 252,000 employed in crafts and freelance professionals and 35,000 employed in agriculture. The most significant sources of employment in 2008 were manufacturing industry and wholesale and retail trade (including motor vehicle repair services) employing 278,640 and 243,640 respectively. Further significant employment sector was construction industry comprising 143,336 jobs that year. In the same year, more than 100,000 were employed in public administration, defence and compulsory social insurance sector as well as in education. Since 2009, negative trends persisted in Croatia with jobs in the industry declined further by 3.5%. Number of unemployed and retired persons combined exceeded number of employed in August 2010, as it fell to 1.474 million. In 2009, labour force consisted of 1.765 million persons out of 3.7 million working age population—aged 15 and over. In October 2011, unemployment rate stood at 17.4%. 7.2% of employed persons hold a second job.

In comparison with the member states of the European Union (EU), Croatia's median equivalent household income in terms of the Purchasing Power Standard (PPS) stands at 470, topping average PPS of the ten countries which joined the EU in 2004 (EU10), as well as Romania and Bulgaria, while significantly lagging behind the EU average. Within Croatia, the highest PPS is recorded in Istria County (769), the City of Zagreb (640) and the Primorje-Gorski Kotar County (576). The lowest PPS is observed in the Bjelovar-Bilogora County and the Virovitica-Podravina County (267).

Urbanisation and housing
2011 census recorded a total of 1,534,148 private households in Croatia as well as 1,487 other residential communities such as retirement homes, convents etc. At the same time, there were 1,923,522 permanent housing units—houses and apartments. 2001 census recorded 1.66 million permanent housing units, including 196 thousand intermittently occupied and 42 thousand abandoned ones. Average size of a permanently used housing unit is 74.4 m2. The intermittently used housing units include 182 thousand vacation houses and 8 thousand houses used during agricultural works. The same census also recorded 25 thousand housing units used for business purposes only. As of 2007, 71% of the households owned their own housing and had no mortgage or other loans to repay related to the housing, while further 9% were repaying loans for their housing. The households vary by type and include single households (13%), couples (15%), single parent households (4%), couples with children (27%) and extended family households (20%). There are approximately 500 homeless persons in Croatia, largely living in Zagreb.

Average urbanisation rate in Croatia stands at 56%, with the maximum rate recorded within the territory of the City of Zagreb, where it reached 94.5% and Zagreb metropolitan area comprising the City of Zagreb and the Zagreb County, where it stands at 76.4%. Very significant rate of urbanisation was observed in the second half of the 20th century. 1953 census recorded 57% of population which was active in agriculture, while a census performed in 1991 noted only 9.1% of population active in that field. This points to augmentation of urban population and reduction of rural population.

Politics of Croatia

The politics of Croatia are defined by a parliamentary, representative democratic republic framework, where the Prime Minister of Croatia is the head of government in a multi-party system. Executive power is exercised by the Government and the President of Croatia. Legislative power is vested in the Croatian Parliament (Sabor). The Judiciary is independent of the executive and the legislature. The parliament adopted the current Constitution of Croatia on 22 December 1990 and decided to declare independence from Yugoslavia on 25 May 1991. The Constitutional Decision on the Sovereignty and Independence of the Republic of Croatia came into effect on 8 October 1991. The constitution has since been amended several times. The first modern parties in the country developed in the middle of the 19th century, and their agenda and appeal changed, reflecting major social changes, such as the breakup of Austria-Hungary, the Kingdom of Serbs, Croats and Slovenes, dictatorship and social upheavals in the kingdom, World War II, the establishment of Communist rule and the breakup of the SFR Yugoslavia.

The President of the Republic (Predsjednik/ica Republike) is the head of state and the commander in chief of the Croatian Armed Forces and is directly elected to serve a five-year term. The government (Vlada), the main executive power of Croatia, is headed by the prime minister, who has four deputy prime ministers who serve also as government ministers. Twenty ministers are in charge of particular activities. The executive branch is responsible for proposing legislation and a budget, executing the laws, and guiding the foreign and internal policies. The parliament is a unicameral legislative body. The number of Sabor representatives (MPs) ranges from 100 to 160; they are elected by popular vote to serve four-year terms. The powers of the legislature include enactment and amendment of the constitution and laws; adoption of the government budget, declarations of war and peace, defining national boundaries, calling referendums and elections, appointments and relief of officers, supervising the Government of Croatia and other holders of public powers responsible to the Sabor, and granting of amnesties. The Croatian constitution and legislation provides for regular presidential and parliamentary elections, and the election of county prefects (county presidents) and assemblies, and city and municipal mayors and councils.

Croatia has a three-tiered, independent judicial system governed by the Constitution of Croatia and national legislation enacted by the Sabor. The Supreme Court (Vrhovni sud) is the highest court of appeal in Croatia, while municipal and county courts are courts of general jurisdiction. Specialised courts in Croatia and the Superior Commercial Court, misdemeanour courts and the Superior Misdemeanour Court, administrative courts and the Superior Administrative Court. Croatian Constitutional Court (Ustavni sud) is a court that deals primarily with constitutional law. Its main authority is to rule on whether laws that are challenged are in fact unconstitutional, i.e., whether they conflict with constitutionally established rights and freedoms. The State Attorney's Office represents the state in legal proceedings.

Legal framework
Croatia is a unitary democratic parliamentary republic. Following the collapse of the ruling Communist League, Croatia adopted a new constitution in 1990 – which replaced the 1974 constitution adopted by the Socialist Republic of Croatia – and organised its first multi-party elections. While the 1990 constitution remains in force, it has been amended four times since its adoption—in 1997, 2000, 2001 and 2010. Croatia declared independence from Yugoslavia on 8 October 1991, which led to the breakup of Yugoslavia. Croatia's status as a country was internationally recognised by the United Nations in 1992. Under its 1990 constitution, Croatia operated a semi-presidential system until 2000 when it switched to a parliamentary system. Government powers in Croatia are divided into legislative, executive and judiciary powers. The legal system of Croatia is civil law and, along with the institutional framework, is strongly influenced by the legal heritage of Austria-Hungary. By the time EU accession negotiations were completed on 30 June 2010, Croatian legislation was fully harmonised with the Community acquis. Croatia became a member state of the European Union on 1 July 2013.

Executive
The President of the Republic (Predsjednik/ica Republike) is the head of state. The president is directly elected and serves a five-year term. The president is the commander in chief of the armed forces, has the procedural duty of appointing the prime minister with the consent of the Sabor (Parliament) through a majority vote (majority of all MPs), and has some influence on foreign policy. The most recent presidential election was held on 11 January 2015 and was won by Zoran Milanović. He took the oath of office on ?. The constitution limits holders of the presidential office to a maximum of two terms and prevents the president from being a member of any political party. Consequently, the president-elect withdraws from party membership before inauguration.

The government (Vlada), the main executive power of Croatia, is headed by the prime minister who has four deputies, who also serve as government ministers. There are 16 other ministers who are appointed by the prime minister with the consent of the Sabor (majority of all MPs); these are in charge of particular sectors of activity. As of 19 October 2016, the Deputy Prime Ministers are Martina Dalić, Davor Ivo Stier, Ivan Kovačić, and Damir Krstičević. Government ministers are from the Croatian Democratic Union (HDZ), and the Bridge of Independent Lists (MOST) with five independent ministers. The executive branch is responsible for proposing legislation and a budget, executing the laws, and guiding the country's foreign and domestic policies. The government's official residence is at Banski dvori. As of 19 October 2016, the prime minister is Andrej Plenković.

Legislature
The Parliament of Croatia (Sabor) is a unicameral legislative body. A second chamber, the Chamber of Counties (Županijski dom), was set up in 1993 pursuant to the 1990 Constitution. The Chamber of Counties was originally composed of three deputies from each of the twenty counties and the city of Zagreb. However, as it had no practical power over the Chamber of Representatives, it was abolished in 2001 and its powers were transferred to the county governments. The number of Sabor representatives can vary from 100 to 160; they are all elected by popular vote and serve four-year terms. 140 members are elected in multi-seat constituencies, up to six members are chosen by proportional representation to represent Croatians living abroad and five members represent ethnic and national communities or minorities. The two largest political parties in Croatia are the Croatian Democratic Union (HDZ) and the Social Democratic Party of Croatia (SDP). The last parliamentary election was held on 11 September 2016 in Croatia and on 10 and 11 September 2016 abroad.

The Sabor meets in public sessions in two periods; the first from 15 January to 30 June, and the second from 15 September to 15 December. Extra sessions can be called by the President of the Republic, by the president of the parliament or by the government. The powers of the legislature include enactment and amendment of the constitution, enactment of laws, adoption of the state budget, declarations of war and peace, alteration of the country's boundaries, calling and conducting referendums and elections, appointments and relief of office, supervising the work of the Government of Croatia and other holders of public powers responsible to the Sabor, and granting amnesty. Decisions are made based on a majority vote if more than half of the Chamber is present, except in cases of constitutional issues.

Elections
The Croatian constitution and legislation provides for regular elections for the office of the President of the Republic, parliamentary, county prefects, county assemblies, city and municipal mayors and city and municipal councils. The President of the Republic is elected to a five-year term by a direct vote of all citizens of Croatia. A majority vote is required to win. A runoff election round is held in cases where no candidate secures the majority in the first round of voting. The presidential elections are regulated by the constitution and dedicated legislation; the latter defines technical details, appeals and similar issues.

140 members of parliament are elected to a four-year term in ten multi-seat constituencies, which are defined on the basis of the existing county borders, with amendments to achieve a uniform number of eligible voters in each constituency to within 5%. Citizens of Croatia living abroad are counted in an eleventh constituency; however, its number of seats was not fixed for the last parliamentary election. It was instead calculated based on numbers of votes cast in the ten constituencies in Croatia and the votes cast in the eleventh constituency. In the 2007 parliamentary election the eleventh constituency elected five MPs. Constitutional changes first applied in the 2011 parliamentary election have abolished this scheme and permanently assigned three MPs to the eleventh constituency. Additionally, eight members of parliament are elected by voters belonging to twenty-two recognised minorities in Croatia: the Serb minority elects three MPs, Hungarians and Italians elect one MP each, Czech and Slovak minorities elect one MP jointly, while all other minorities elect two more MPs to the parliament. The Standard D'Hondt formula is applied to the vote, with a 5% election threshold. The last parliamentary election, held in 2016, elected 151 MPs.

The county prefects and city and municipal mayors are elected to four-year terms by majority of votes cast within applicable local government units. A runoff election is held if no candidate achieves a majority in the first round of voting. Members of county, city, and municipal councils are elected to four-year terms through proportional representation; the entire local government unit forms a single constituency. The number of council members is defined by the councils themselves based on applicable legislation. Electoral committees are then tasked with determining whether the national minorities are represented in the council as required by the constitution. If the minorities are not represented, further members, who belong to the minorities and who have not been elected through the proportional representation system, are selected from electoral candidate lists and added to the council.

Judiciary
Croatia has a three-tiered, independent judicial system governed by the constitution and national legislation enacted by the Sabor. The Supreme Court (Vrhovni sud) is the highest court of appeal in Croatia; its hearings are open and judgments are made publicly, except in cases where the privacy of the accused is to be protected. Judges are appointed by the National Judicial Council and judicial office is permanent until seventy years of age. The president of the Supreme Court is elected for a four-year term by the Croatian Parliament at the proposal of the President of the Republic. As of 2017, the president of the Supreme Court is Đuro Sessa. The Supreme Court has civil and criminal departments. The lower two levels of the three-tiered judiciary consist of county courts and municipal courts. There are fifteen county courts and sixty-seven municipal courts in the country.

There are other specialised courts in Croatia; commercial courts and the Superior Commercial Court, misdemeanour courts that try trivial offences such as traffic violations, the Superior Misdemeanour Court, the Administrative Court and the Croatian Constitutional Court (Ustavni sud). The Constitutional Court rules on matters regarding compliance of legislation with the constitution, repeals unconstitutional legislation, reports any breaches of provisions of the constitution to the government and the parliament, declares the speaker of the parliament acting president upon petition from the government in the event the country's president becomes incapacitated, issues consent for commencement of criminal procedures against or arrest of the president, and hears appeals against decisions of the National Judicial Council. The court consists of thirteen judges elected by members of the parliament for an eight-year term. The president of the Constitutional Court is elected by the court judges for a four-year term. As of June 2012, the president of the Constitutional Court is Jasna Omejec. The National Judicial Council (Državno Sudbeno Vijeće) consists of eleven members, specifically seven judges, two university professors of law and two parliament members, nominated and elected by the Parliament for four-year terms, and may serve no more than two terms. It appoints all judges and court presidents, except in case of the Supreme Court. As of January 2015, the president of the National Judicial Council is Ranko Marijan, who is also a Supreme Court judge.

The State Attorney's Office represents the state in legal procedures. As of April 2018, Dražen Jelenić is the General State Attorney, and there are twenty-three deputies in the central office and lower-ranking State Attorneys at fifteen county and thirty-three municipal State Attorney's Offices. The General State Attorney is appointed by the parliament. A special State Attorney's Office dedicated to combatting corruption and organised crime, USKOK, was set up in late 2001.

Local government
Croatia was first subdivided into counties (županija) in the Middle Ages. The divisions changed over time to reflect losses of territory to Ottoman conquest and the subsequent recapture of the same territory, and changes to the political status of Dalmatia, Dubrovnik and Istria. The traditional division of the country into counties was abolished in the 1920s, when the Kingdom of Serbs, Croats and Slovenes and the subsequent Kingdom of Yugoslavia introduced oblasts and banovinas respectively. After 1945 under Communist rule, Croatia, as a constituent part of Yugoslavia, abolished these earlier divisions and introduced municipalities, subdividing Croatia into approximately one hundred municipalities. Counties, significantly altered in terms of territory relative to the pre-1920s subdivisions, were reintroduced in 1992 legislation. In 1918, the Transleithanian part of Croatia was divided into eight counties with their seats in Bjelovar, Gospić, Ogulin, Požega, Vukovar, Varaždin, Osijek and Zagreb; the 1992 legislation established fifteen counties in the same territory. Since the counties were re-established in 1992, Croatia is divided into twenty counties and the capital city of Zagreb, the latter having the authority and legal status of a county and a city at the same time. In some instances, the boundaries of the counties have been changed, with the latest revision taking place in 2006. The counties subdivide into 128 cities and 428 municipalities.

The county prefects, city and municipal mayors are elected to four-year terms by a majority of votes cast within applicable local government units. If no candidate achieves a majority in the first round, a runoff election is held. Members of county, city and municipal councils are elected to four-year terms, through proportional representation with the entire local government unit as a single constituency.

The number of members of the councils is defined by the councils themselves, based on applicable legislation. Electoral committees are then tasked with determining whether the national ethnic minorities are represented on the council as required by the constitution. Further members who belong to the minorities may be added to the council if no candidate of that minority has been elected through the proportional representation system. Election silence, as in all other types of elections in Croatia, when campaigning is forbidden, is enforced the day before the election and continues until 19:00 hours on the election day when the polling stations close and exit polls may be announced. Eight nationwide local elections have been held in Croatia since 1990, the most recent being the 2017 local elections to elect county prefects and councils, and city and municipal councils and mayors. In 2017, the HDZ-led coalitions won a majority or plurality in fifteen county councils and thirteen county prefect elections. SDP-led coalitions won a majority or plurality in five county councils, including the city of Zagreb council, and the remaining county council election was won by IDS-SDP coalition. The SDP won two county prefect elections, the city of Zagreb mayoral election, the HSS and the HNS won a single county prefect election each.

Within Austria-Hungary

Events of 1848 in Europe and the Austrian Empire brought dramatic changes to Croatian society and politics, provoking the Croatian national revival that strongly influenced and significantly shaped political and social events in Croatia. At the time, the Sabor and Ban Josip Jelačić advocated the severance of ties with the Kingdom of Hungary, emphasising links to other South Slavic lands within the empire. Several prominent Croatian political figures emerged, such as Ante Starčević, Eugen Kvaternik, Franjo Rački and Josip Juraj Strossmayer. A period of neo-absolutism was followed by the Austro-Hungarian Compromise of 1867 and the Croatian–Hungarian Settlement, which granted limited independence to Croatia. This was compounded by Croatian claims of uninterrupted statehood since the early Middle Ages as a basis for a modern state. Two political parties that evolved in the 1860s and contributed significantly to the sentiment were the Party of Rights, led by Starčević and Kvaternik, and the People's Party, led by Janko Drašković, Ivan Kukuljević Sakcinski, Josip Juraj Strossmayer and Ivan Mažuranić. They were opposed by the National Constitutional Party, which was in power for most of the period between the 1860s and the 1918, and advocated closer ties between Croatia and Hungary.

Other significant parties formed in the era were the Serb People's Independent Party, which later formed the Croat-Serb Coalition with the Party of Rights and other Croat and Serb parties. The Coalition ruled Croatia between 1903 and 1918. The leaders of the Coalition were Frano Supilo and Svetozar Pribićević. The Croatian Peasant Party (HSS), established in 1904 and led by Stjepan Radić, advocated Croatian autonomy but achieved only moderate gains by 1918. In Dalmatia, the two major parties were the People's Party – a branch of the People's Party active in Croatia-Slavonia – and the Autonomist Party, advocating maintaining autonomy of Dalmatia, opposite to the People's Party demands for unification of Croatia-Slavonia and Dalmatia. The Autonomist Party, most notably led by Antonio Bajamonti, was also linked to Italian irredentism. By 1900, the Party of Rights had made considerable gains in Dalmatia. The Autonomists won the first three elections, but all elections since 1870 were won by the People's Party. In the period 1861–1918 there were seventeen elections in the Kingdom of Croatia-Slavonia and ten in the Kingdom of Dalmatia.

First and Second Yugoslavia
After the establishment of the Kingdom of Serbs, Croats and Slovenes, the HSS established itself as the most popular Croatian political party and was very popular despite efforts to ban it. The 1921 constitution defined the kingdom as a unitary state and abolished the historical administrative divisions, which effectively ended Croatian autonomy; the constitution was opposed by HSS. The political situation deteriorated further as Stjepan Radić of the HSS was assassinated in the Yugoslav Parliament in 1928, leading to the dictatorship of King Alexander in January 1929. The HSS, now led by Vladko Maček, continued to advocate the federalisation of Yugoslavia, resulting in the Cvetković–Maček Agreement of August 1939 and the autonomous Banovina of Croatia. The Yugoslav government retained control of defence, internal security, foreign affairs, trade, and transport while other matters were left to the Croatian Sabor and a crown-appointed Ban. This arrangement was soon made obsolete with the beginning of World War II, when the Independent State of Croatia, which banned all political opposition, was established. Since then, the HSS continues to operate abroad.

In the 1945 election, the Communists were unopposed because the other parties abstained. Once in power, the Communists introduced a single-party political system, in which the Communist Party of Yugoslavia was the ruling party and the Communist Party of Croatia was its branch. In 1971, the Croatian national movement, which sought greater civil rights and the decentralisation of the Yugoslav economy, culminated in the Croatian Spring, which was suppressed by the Yugoslav leadership. In January 1990, the Communist Party fragmented along national lines; the Croatian faction demanded a looser federation.

Modern Croatia
In 1989, the government of the Socialist Republic of Croatia decided to tolerate political parties in response to growing demands to allow political activities outside the Communist party. The first political party founded in Croatia since the beginning of the Communist rule was the Croatian Social Liberal Party (HSLS), established on 20 May 1989, followed by the Croatian Democratic Union on 17 June 1989. In December 1989, Ivica Račan became the head of the reformed Communist party. At the same time, the party cancelled political trials, released political prisoners and endorsed a multi-party political system. The Civil Organisations Act was formally amended to allow political parties on 11 January 1990, legalising the parties that were already founded.

By the time of the first round of the first multi-party elections, held on 22 April 1990, there were 33 registered parties. The most relevant parties and coalitions were the League of Communists of Croatia – Party of Democratic Changes (the renamed Communist party), the Croatian Democratic Union (HDZ), and the Coalition of People's Accord (KNS), which included the HSLS led by Dražen Budiša, and the HSS, which resumed operating in Croatia in December 1989. The runoff election was held on 6 May 1990. The HDZ, led by Franjo Tuđman, won ahead of the reformed Communists and the KNS. The KNS, led by Savka Dabčević-Kučar and Miko Tripalo – who had led the Croatian Spring – soon splintered into individual parties. The HDZ maintained a parliamentary majority until the 2000 parliamentary election, when it was defeated by the Social Democratic Party of Croatia (SDP), led by Račan. Franjo Gregurić, of the HDZ, was appointed prime minister to head a national unity government in July 1991 as the Croatian War of Independence escalated in intensity. His appointment lasted until August 1992. During his term, Croatia's declaration of independence from Yugoslavia took effect on 8 October 1991. The HDZ returned to power in the 2003 parliamentary election, while the SDP remained the largest opposition party.

Franjo Tuđman won the presidential elections in 1992 and 1997. During his terms, the Constitution of Croatia, adopted in 1990, provided for a semi-presidential system. After Tuđman's death in 1999, the constitution was amended and much of the presidential powers were transferred to the parliament and the government. Stjepan Mesić won two consecutive terms in 2000 and 2005 on a Croatian People's Party (HNS) ticket. Ivo Josipović, an SDP candidate, won the presidential elections in December 2009 and January 2010. Kolinda Grabar-Kitarović defeated Josipović in the January 2015 election run-off, becoming the first female president of Croatia.

In January 2020, former prime minister Zoran Milanovic of the Social Democrats (SDP) won the presidential election. He defeated center-right incumbent Kolinda Grabar-Kitarovic of the ruling Croatian Democratic Union (HDZ) in the second round of the election. In July 2020, the ruling right-wing HDZ won the parliamentary election. Since 2016 ruled HDZ-led coalition of prime minister Andrej Plenković continued to govern.
