Gridded Population of the World, Version 3 (GPWv3): National Administrative Boundaries

The Gridded Population of the World, Version 3 (GPWv3): National Administrative Boundaries are derived from the land area grid to show the outlines of pixels (cells) that contain administrative units in GPWv3 on a per-country/territory basis. The National Boundaries data are derived from the pixels as polygons and thus have rectilinear boundaries at large scale. Note that the polygons that outline the countries and territories are not official representations; rather, they represent the area covered by the statistical data as provided. The national/territorial boundaries are designed for cartographic use with the GPWv3 population raster data sets. GPWv3 is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with Centro Internacional de Agricultura Tropical (CIAT).
To provide a quantitative measure of the input resolution of administrative units used for GPWv3.
