and is only built-up on two minor areas. It also includes along the harbour and around Bella Center (which hosted the climate meeting COP 15 in December 2009). Apart from these smaller areas and an allotment-garden cottage area, the vast majority of western Amager is unplanned, with few buildings (like a shooting range). The cause for this creation was mainly to give shelter to the southern part of Copenhagen harbour. Since the area is now filled out with big stones, sand from the sea, plaster, wastes and unknown items, building in the area is expensive. Not even agriculture is possible due to bad soil. (However the southern part of Amager has agricultural areas and even a small forest, "Kongelunden" ("King Grove"). These areas belong to a third municipality of Amager island, Dragør.) Some of the unused area belongs to Copenhagen Municipality, but the Dragør Municipality and Tårnby Municipality part is far larger. Also the almost unpopulated islands of "Saltholm" (3 inhabitants in 2010) and "Peberholm" (unpopulated) belongs to Tårnby, and so does the taxi and runway system of Copenhagen Airport (with three long runways). In all, most of Tårnby and a minor part of Copenhagen municipalities on Amager island cannot be regarded as an urban area. Consequently, "Hovedstadsområdet" does not equal an urban area of Copenhagen. Neither the Danish statistic authority "Danmarks Statistik" (which presents information regarding "Hovedstadsområdet") or the Danish geographical institute "Kort og Matrikelstyrelsen" (which determines the borders of "Hovedstadsområdet") states that "Hovedstadsområdet" is an urban area of Copenhagen. For internal Danish matters this is of no importance. But when comparing Copenhagen with other cities, the unpopulated non-urban areas of Amager, Saltholm and Peberholm do make a difference in f.i. terms of population density. , Copenhagen lacks official urban borders for comparison with other cities. "Hovedstadsområdet" is an area invented primarily for statistical matters. It's rarely used in conversation (as a defined area). Sometimes in media the word "Hovedstadsområdet" represents a metropolitan area from Køge in the south to Elsinore in the north and Roskilde in the west. For instance, a regional television channel called "Hovedstads-TV", "Kanal Hovedstaden", "Kanal København" and "TV2 Lorry" and other "Local-TV Channels" covers this larger area and so on. But even in nationwide public service television news, the word "Hovedstadsområdet" may refer to either what the Danish statistic institute defines as "Hovedstadsområdet" or the metropolitan area. Another similar area is "Storkøbenhavn" (eng. "Greater
