Gridded Population of the World, Version 4 (GPWv4): Administrative Unit Center Points with Population Estimates

The Gridded Population of the World, Version 4 (GPWv4) Administrative Unit Center Points with Population Estimates consists of UN-adjusted estimates of human population counts and densities for the years 2000, 2005, 2010, 2015 and 2020 by administrative unit center point (centroid) location. Specifically, the population data were adjusted to the 2015 Revision of UN World Population Prospects. The center points are based on approximately 12.5 million input administrative units used in GPWv4. Additionally, the administrative unit names, unit areas, and data context of the units are included.
