The pes-v2 service accepts polygons that define areas of interest, and a string which selects a year from the set of 2000, 2005, 2010, 2015 or 2020 then returns population totals, land area, quality measures, and basic parametric statistics for the requested polygons based on data from SEDAC’s Gridded Population of the World version 4 (GPWv4) dataset.
