Summary
Abstract: Gridded Population of the World, Version 3 (GPWv3) Land and Geographic Unit Area Grids measure land areas in square kilometers and the mean unit size (population-weighted) in square kilometers. The land area grid permits the summation of areas (net of permanent ice and water) at the same resolution as the population density, count, and urban-rural grids. The mean unit size grids provides a ... View entire text

Purpose: To provide a quantitative measure of the input resolution of administrative units used for GPWv3.
