The conurbation of Copenhagen consists of several municipalities. The central and largest is Copenhagen municipality, the second largest is Frederiksberg municipality which is an enclave inside Copenhagen municipality. Both are contained in the larger Copenhagen Capital Region, which contains most of the Copenhagen metropolitan area.
Previously, the areas of Frederiksberg, Gentofte and Copenhagen municipalities have been used to define the city of Copenhagen. This definition is now obsolete. To meet statistical needs after the latest municipal reform, which took place in the beginning of 2007, an effort has been made to work out definitions of lands (landsdele) in Denmark. A land is basically a geographical and statistical definition, and the area is not considered to be an administrative unit. The land of Copenhagen City includes the municipalities of Copenhagen, Dragør, Frederiksberg and Tårnby, with a total population of 656,582 in the beginning of 2008.
Copenhagen and Frederiksberg were two of the three last Danish municipalities not belonging to a county. On 1 January 2007, the municipalities lost their county privileges and became part of Copenhagen Capital Region.
