description:

Gridded Population of the World, Version 4 (GPWv4) National Identifier Grid, Revision 11 is a polygon representation of nation-states in GPWv4 for use in aggregating population data. This data set is produced from the input census units and is used to create a raster surface where pixels that cover the same census data source (most often a country or territory) have the same value. The raster was converted to polygon features. Note that these data are not official representations of country boundaries; rather, they represent the area covered by the input data. The files for this data set were produced as global grids at 30 arc-seconds horizontal resolution (approximately 1km at the equator). To enable faster global processing, and in support of research communities, the 30 arc-second data was aggregated to 2.5 arc-minutes, 15 arc-minutes, 30 arc-minutes and 1 degree resolutions.
