The area doesn't follow the recommendations of the United Nations regarding urban definitions (i.e. 200 meters between buildings as the required minimum) and is used for statistic issues only. The main difference between "Hovedstadsområdet" and common urban area definition (or city limits) involves the islands of Amager, Saltholm and Peberholm, and primarily the municipality of Tårnby. Copenhagen Municipality, Tårnby Municipality and Dragør Municipality is the three Municipality’s on The Island of Amager. "Hovedstadsområdet" contains the entire Copenhagen and Tårnby municipalities, although the latter contains large areas without buildings and inhabitants. This also applies to a smaller part of Copenhagen on Amager island. The western part of Amager is an enlargement from a shallow part of the Øresund sea, gained from the sea during the 1930s to 1950s. This extended part of Amager is split between Copenhagen and Tårnby municipalities,
