A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories which share industries , commercial areas , transport network , infrastructures and housing . A metropolitan area usually comprises multiple principal cities , jurisdictions and municipalities : neighborhoods , townships , boroughs , cities , towns , exurbs , suburbs , counties , districts and even states and nations in areas like the eurodistricts . As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.

According to Urbanization by sovereign state article, the world as a whole is 56.2% urbanized, with roughly one-quarter of the countries reported as greater than 80% urbanized. Data is taken from the U.S. Central Intelligence Agency World Factbook estimates from 2020. According to Demographia, these are the 202 largest urban areas in the world by population (as of 2023): The UN publishes data on cities, urban areas and rural areas, but relies almost entirely on national definitions of these areas.

Urban areas are created and further developed by the process of urbanization. They are measured for various purposes, including analyzing population density and urban sprawl . Urban areas are also mostly found in

European countries define urbanized areas on the basis of urban-type land use , not allowing any gaps of typically more than 200 metres (220 yd), and use satellite imagery instead of census blocks to determine the boundaries of the urban area. In less-developed countries , in addition to land use and density requirements, a requirement that
