Croatia contains the administrative territorial entity Vukovar-Syrmia County
Communist-ruled Croatia, as a constituent part of post-World War II Yugoslavia, abolished earlier divisions and introduced municipalities, subdividing Croatia into approximately one hundred municipalities. Counties were reintroduced in 1992 legislation, significantly altered in terms of territory relative to the pre-1920s subdivisions. In 1918, the Transleithanian part was divided into eight counties with their seats in Bjelovar, Gospić, Ogulin, Osijek, Požega, Varaždin, Vukovar, and Zagreb.As of 1992, Croatia is divided into 20 counties and the capital city of Zagreb, the latter having the dual authority and legal status of a county and a city. County borders changed in some instances, last revised in 2006. The counties subdivide into 127 cities and 429 municipalities. Nomenclature of Territorial Units for Statistics (NUTS) division is performed in several tiers. NUTS 1 level considers the entire country in a single unit; three NUTS 2 regions come below that. Those are Northwest Croatia, Central and Eastern (Pannonian) Croatia, and Adriatic Croatia. The latter encompasses the counties along the Adriatic coast. Northwest Croatia includes Koprivnica-Križevci, Krapina-Zagorje, Međimurje, Varaždin, the city of Zagreb, and Zagreb counties and the Central and Eastern (Pannonian) Croatia includes the remaining areas—Bjelovar-Bilogora, Brod-Posavina, Karlovac, Osijek-Baranja, Požega-Slavonia, Sisak-Moslavina, Virovitica-Podravina, and Vukovar-Syrmia counties. Individual counties and the city of Zagreb also represent NUTS 3 level subdivision units in Croatia. The NUTS local administrative unit divisions are two-tiered. LAU 1 divisions match the counties and the city of Zagreb in effect making those the same as NUTS 3 units, while LAU 2 subdivisions correspond to cities and municipalities.
