A calibrated annual gridded population dataset for mainland China from 2010 to 2020 integrates township-level census data and county-level statistical yearbooks. The 18.7 GB dataset, created by lanhui li and last updated in May 2026, uses a two-stage method to correct and scale original WorldPop, GlobPop, and LandScan raster products. Evaluation indicates its spatiotemporal consistency and spatial accuracy exceed those of the original source products.
Data is provided in TIF format, requiring GIS software for analysis. The 18.7 GB size necessitates significant storage and processing capacity.
