In view of possible influences of geographical factors, this study analyzes the differences in accuracy of population estimation of four mainstream spatialized population datasets: the History Database of the Global Environment version 3.2.000 (HYDE), Gridded Population of the World version 4 (GPWv4), Global Human Settlement Layer (GHSL), and WorldPop. The analysis is done by computing relative errors and population spatial distribution consistency in different regions by comparing datasets pixel by pixel.
