Spatial distribution consistency of four datasets in each case area (completely consistent: four datasets are consistent; highly consistent: three datasets are consistent; lowly consistent: two datasets are consistent; completely inconsistent: each dataset is inconsistent with the others)

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.
