Description: Gridded Population of the World, Version 4 (GPWv4) Population Density Adjusted to Match 2015 Revision of UN WPP Country Totals, Revision 11 consists of estimates of human population density based on counts consistent with national censuses and population registers with respect to relative spatial distribution, but adjusted to match the 2015 Revision of UN World Population Prospects country totals for the years 2000, 2005, 2010, 2015, and 2020. A proportional allocation gridding algorithm, utilizing approximately 13.5 million national and sub-national administrative units, is used to assign adjusted population counts to 30 arc-second (approximately 1 km at the equator) pixels. The adjusted population count rasters are divided by the land area raster to produce adjusted population density rasters with pixel values representing persons per square kilometer.
