Zoom in and out to see the variations and patterns of population distribution. These high-resolution maps estimate not only the number of people living within 30-meter grid tiles, but also provide insights on demographics at unprecedentedly high resolutions. Source imagery for HRSL © 2016 DigitalGlobe. How crowded is the USA Explore this interactive map that shows the population density of every county in the country, based on the latest census data. United States: High Resolution Population Density Maps + Demographic Estimates.

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. Identify global megacity regions and the growth and diversity of urban forms. The UN estimate for a given country (or state/territory) is divided by the total census estimate of population for the given country. Explore the detailed geography of population across the globe with interactive mapping and statistics. 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. United States: High Resolution Population Density Maps + Demographic Estimates. To create our high-resolution maps, we use machine learning techniques to identify buildings from commercially available satellite images. Maps were created by Alasdair Rae, using Aerialod software and population density data. Creative Commons Attribution International
