Demographia World Urban Areas (Built-up Urban Areas or Urban Agglomerations) is the only annually published inventory of population, corresponding land area and population density for urban areas with more than 500,000 population. Unlike some other regularly produced lists, Demographia World Urban Areas applies a generally consistent definition to built-up urban areas.Urban footprint data is reported without regard to political boundaries that are generally associated with metropolitan areas or sub-national jurisdictions. As used in this report, all instances of the term “urban area” are defined as “built-up urban
area.An urban area (“built-up urban area,”5 urbanized area or urban agglomeration)6 is a continuously built up land mass of urban development that is within a labor market (metropolitan area or metropolitan region). An urban area contains no rural land (all land in the world is either urban or rural). In some nations, the term “urban area” is used, but does not denote a built-up urban area.Demographia World Urban Areas is in its 15th year of publication. It was established for the purpose of bringing consistency to the subject of urban density, in hopes of replacing anecdotal comparisons between cities that are often grossly invalid. The built-up urban area is the only level at which there is sufficient data to estimate the densities of the urban organism at anything approximating international standards. Even with this data, the science of urban area density is in its infancy.MethodologyDemographia uses maps, satellite photographs to estimate continuous urbanization. Demographia also uses small area population data, where available, to match population estimates to urban land area.The current year population estimate is modeled from the base year population, adjusted by population projections between the base year and the current year. Most population projections are from the United Nations.
