Demographia defines an urban area (urbanized area agglomeration or urban centre) as a continuously built up landmass of urban development containing a high population density, without regard for administrative boundaries (i.e. municipality, city or commune) or a labor market (i.e. metropolitan area). Demographia uses maps, satellite photographs to estimate continuous urbanization. Demographia also uses small area population data, where available, to match population estimates to urbanized land area
