Latvia is a unitary state, currently divided into 42 local government units consisting of 35 municipalities () and 7 state cities () with their own city council and administration: Daugavpils, Jelgava, Jūrmala, Liepāja, Rēzekne, Riga, and Ventspils. There are four historical and cultural regions in Latvia – Courland, Latgale, Vidzeme, Zemgale, which are recognised in Constitution of Latvia. Selonia, a part of Zemgale, is sometimes considered culturally distinct region, but it is not part of any formal division. The borders of historical and cultural regions usually are not explicitly defined and in several sources may vary. In formal divisions, Riga region, which includes the capital and parts of other regions that have a strong relationship with the capital, is also often included in regional divisions; e.g., there are five planning regions of Latvia (), which were created in 2009 to promote balanced development of all regions. Under this division Riga region includes large parts of what traditionally is considered Vidzeme, Courland, and Zemgale. Statistical regions of Latvia, established in accordance with the EU Nomenclature of Territorial Units for Statistics, duplicate this division, but divides Riga region into two parts with the capital alone being a separate region.
