China County Geography and Population Data for 1990

County-level data for China in 1990 includes area in hectares, centroid latitude and longitude, and population counts. This dataset was compiled by SCIOPS from multiple Chinese sources as an input for the DNDC agricultural ecosystem model. It represents one of seven thematic collections for that year.

Use Cases

• Calculate population density per county using the population and area_hectares columns.
• Georeference other county-level agricultural data using the centroid_latitude and centroid_longitude fields.
• Analyze correlations between population size and other modeled variables like crop yields or livestock counts.
• Serve as a spatial join key for integrating the seven datasets in the China County Data collection.

Strengths

• Data is compiled at a consistent county scale for the entire country of China.
• Provides three core geographic and demographic variables: area, centroid coordinates, and population.

Limitations

• Data is temporally stale, representing a single snapshot from 1990.
• The small number of variables (3) limits standalone analytical depth.
• Unknown row count and sample size prevent assessment of completeness.
