AB  - This dataset comprises three periods (2000, 2010, and 2020) of county-level population census spatial distribution raster data for the Yellow River Basin. Based on the fifth, sixth, and seventh national population censuses at the county level, the Excel-formatted population data were first vectorized. These vector data were then combined with land use information to perform rasterization processing through a zonal density mapping model. Population density values were allocated to 1 km resolution cells, ultimately generating continuous population distribution rasters. All datasets were projected into the CGCS2000 Albers coordinate system. The data include population density rasters from three distinct time periods, covering the entire Yellow River Basin with a temporal interval of 10 years and a spatial resolution of 1 km.
