Calibrated Annual Population Grids for China from 2010 to 2020

18.1 GB of calibrated gridded population data for mainland China from 2010 to 2020. The dataset was created by lanhui li using a two-stage method that integrates township-level census data with county-level statistical yearbook figures to correct and scale original WorldPop, GlobPop, and LandScan rasters. Evaluation indicates its spatiotemporal consistency and spatial accuracy are higher than the original source products.

Use Cases

• Modeling population distribution changes based on calibrated annual grids from 2010 to 2020.
• Validating other population estimation products using the dataset's reported higher spatial accuracy.
• Analyzing demographic trends at sub-county levels using township-scale interpolated data.
• Informing infrastructure and resource allocation planning with population data consistent with official statistics.

Strengths

• Dataset size of 18.1 GB indicates detailed spatial coverage.
• Covers an 11-year time range from 2010 to 2020.
• Integrates multiple data sources: census data, statistical yearbooks, and three global population grid products.
• Reported higher spatiotemporal consistency and spatial accuracy than original GlobPop, LandScan, and WorldPop products.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data for Hong Kong, Macao, and Taiwan is excluded, limiting geographic completeness.
• The dataset is split across multiple files (Part 1, Part 2, Part 3), which may complicate access.
