Gridded Population of the World, Version 3 (GPWv3): CentroidsEntry ID: CIESIN_SEDAC_GPWv3_CENTROIDS
Abstract: Gridded Population of the World, Version 3 (GPWv3) Centroids consists of estimates of human population counts and densities for the years 1990, 1995, 2000, 2005, 2010, and 2015 by administrative unit centroid location. The centroids are based on the 399,781 input administrative units used in GPWv3. In addition to population counts and variables, the centroids have associated administrative unit ... names and the land area of contained within the administrative unit. GPWv3 is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with Centro Internacional de Agricultura Tropical (CIAT).
The data in Comma Separated Version (CSV) and ESRI Shapefile (SHP) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
Purpose: To provide a vector (point) version of the input administrative units used in GPWv3 for use in data integration.
