(New Map Viewer Only) This map is designed to work in the new ArcGIS Online Map Viewer. The pattern is shown using American Community Survey (ACS) data by states, counties, and tracts. This is shown by dot density, where each dot represents multiple people. The population density in the United States saw no significant changes in 2021 in comparison to the previous year 2020 and remained at around 36.3 inhabitants per square kilometer.

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. Then we work with our partners at Columbia University to overlay general population estimates based on publicly available census data and other population statistics. To create our high-resolution maps, we use machine learning techniques to identify buildings from commercially available satellite images. and World Population Clock United States main page World main page.
