This preserves the relative population totals across administrative units while matching the UN total. The resulting adjustment factor is multiplied by each administrative unit census value for the target year. The UN estimate for a given country (or state/territory) is divided by the total census estimate of population for the given country. For more information about the methodology used to create our high resolution population density maps and the demographic distributions, please visit: įor information about how to use HDX to access these datasets, please visit: Īdjustments to match the census population with the UN estimates are applied at the national level. The resulting maps are the most detailed and actionable tools available for aid and research organizations. Density rankings 1 to 52 include the District of Columbia and Puerto Rico. Note: Population density is a measure of the average population per square mile of land. Then we work with our partners at Columbia University to overlay general population estimates based on publicly available census data and other population statistics. 1 Includes the resident population of the 50 states and the District of Columbia, as ascertained by the Decennial Census. To create our high-resolution maps, we use machine learning techniques to identify buildings from commercially available satellite images.
