Since the counties were re-established in 1992, Croatia is 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. Borders of the counties changed in some instances since, with the latest revision taking place in 2006. The counties subdivide into 127 cities and 429 municipalities. 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. Those are Northwest Croatia, Central and Eastern (Pannonian) Croatia, and Adriatic Croatia. The latter encompasses all 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 the cities and municipalities of Croatia.
