Network and the Hierarchy of the Cities in the Global World: Challenge to Nation-States and Limits of the Expansion

Abstract

Some other urban agglomeration lists mix metropolitan areas, municipalities (parts of metropolitan areas) and urban areas (built up urban areas or agglomerations). None of these lists include urban land area data. The United Nations list is unique in providing notes that clarify the nature of its each of its listings (core cities, metropolitan areas, urban areas and others). 2 Calculated using United Nations data.
