Croatia's application to become an EU member state was initially suspended pending resolution of its border disputes with Slovenia.

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

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.

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.
