Annual Population Grids for China (2010–2020) Calibrated with Census and Yearbook Data

Yearly gridded population data for mainland China from 2010 to 2020, calibrated using a two-stage method. The dataset integrates township-level census data and county-level statistical yearbooks to correct and scale original GlobPop, LandScan, and WorldPop rasters. Created by lanhui li and released under CC-BY-4.0, the 13.5 GB dataset is provided as TIF files.

Use Cases

• Modeling population density changes over time based on the calibrated annual grids.
• Validating and comparing global population products using the described higher spatial accuracy.
• Analyzing regional demographic trends by integrating the township-scale interpolated data.
• Supporting infrastructure and resource allocation planning with population data consistent with official statistics.

Strengths

• 13.5 GB of high-resolution geospatial data, indicating a large-scale resource.
• Evaluation shows higher spatiotemporal consistency and spatial accuracy than original GlobPop, LandScan, and WorldPop products.
• Calibrated year-by-year with official county-level (and some municipal and provincial) statistical yearbook data from 2011–2019.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset excludes Hong Kong, Macao, and Taiwan, limiting geographic coverage.
• Row count is unknown, which may limit suitability assessment for some analytical tasks.
