The Croatian economy is significantly centralized, as the bulk of its GDP (31.4%) is generated within the nation's capital and the most populous city—Zagreb.[3] The city administered area covers 1.1% of territory,[4] and encompasses 18.4% of Croatia's population.[5]
According to 2009 data, by far the largest GDP is generated in the city of Zagreb, which is constituted as a county and a city at the same time.[4] GDP of the city of Zagreb amounts to 14,079 billion Euro, surpassing the second ranked county in terms of GDP—Split-Dalmatia County—by more than 10 billion Euro. The Split-Dalmatia is closely followed by Primorje-Gorski Kotar County, the two counties centering on the second and third largest cities in Croatia—Split and Rijeka—and benefiting from considerable trade, processing industry, and tourism.[6][7]
The two counties contribute 8.6% and 8.4% of Croatia's GDP respectively. Three following counties, ranked by the GDP, are Istria, Osijek-Baranja and Zagreb counties—the latter encompassing territory surrounding the capital. The lowest GDP is achieved by Lika-Senj, Požega-Slavonia and Virovitica-Podravina counties. The low figures, ranging from 435 to 561 million Euro are consequence of not only low level of economic development, but also of low populations of the counties.
All the counties recorded steady growth of their GDP until 2008, when the values peaked. Between 2000 and 2008 Croatian GDP grew by 105%, but growth of economy in the individual counties was not uniform—the growth in the period ranged from 60% recorded in the Sisak-Moslavina County to as much as 154% in the Zadar County. The greatest growth rate in the period, besides the Zadar County, was achieved by Dubrovnik-Neretva (135%) and Šibenik-Knin counties as well as the city of Zagreb (120%). In 2009, Croatian GDP fell by 5.5%, with similarly uneven variation of the county GDP figures. The largest drops were recorded in Virovitica-Podravina (−15.1%), Lika-Senj (−11.6%), Šibenik-Knin (−11.4%) and Krapina-Zagorje (−11.3%) counties. The lowest rate of economic decline was observed in Istria (−2.5%), Zagreb (−2.6%) and Sisak-Moslavina (−2.6%) counties.[8]
The highest nominal GDP per capita is recorded in the City of Zagreb at 22,695 Euro in 2018. The second, third and fourth ranked counties in terms of the GDP per capita are Istria, Primorje-Gorski Kotar and Dubrovnik-Neretva, at 15,570 Euro, 14,797 Euro and 13,277 Euro respectively. The four are the only counties of Croatia enjoying GDP per capita exceeding national average of 12,270 Euro. The lowest GDP per capita is recorded in the Virovitica-Podravina (6,525 Euro), Brod-Posavina (6,607 Euro) and Požega-Slavonia (6,620 Euro) counties.[10]
The city of Zagreb ranks first among and the counties of Croatia in terms of the GDP per capita continuously since 2000. The Istria County or the Primorje-Gorski Kotar County rank the second and third throughout the period except in 2004, when the Lika-Senj County takes third place. The largest net change of the ranking was achieved by the Šibenik-Knin County, improving its ranking by 11 places since 2000 when its GDP per capita was the 19th largest in Croatia. The Brod-Posavina, Požega-Slavonia, Virovitica-Podravina and Vukovar-Syrmia counties occupy the last four rankings continuously since 2000.[11]
