GEO2_CN identifies the household's prefecture or city within China in all sample years. Prefectures or cities are the second level administrative units of the country, after provinces. GEO2_CN is spatially harmonized to account for political boundary changes across census years. Some detail is lost in harmonization; see the comparability discussion. A GIS map (in shapefile format), corresponding to GEO2_CN can be downloaded from the GIS Boundary files page in the IPUMS International web site.

The full set of geography variables for China can be found in the IPUMS International Geography variables list. For cross-national geographic analysis on the first and second major administrative level refer to GEOLEV1, and GEOLEV2. More information on IPUMS-International geography can be found here.

Comparability — General

Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time.

Boundary changes for GEO2_CN are too numerous to list here, but users should be aware that there were changes over time.

The 2000 sample is missing 4 prefectures/cities that were originally coded as "Hubei Province direct administrative area." These prefectures/cities are not contiguous and are given unique identifiers in shapefiles.
These prefectures/cities are:

  • Xiantao city
  • Qianjiang city
  • Shennongjia district
  • Tianmen city
