Codes and Frequencies
Most IPUMS data transformations are performed using variable harmonization tables that specify how each value in the source data is recoded. Some variables also require programming logic in addition to the harmonization table. The harmonization documents for this variable are:
GEO2_ TH1970 identifies the household's district within Thailand in 1970. Districts are the second level administrative units of the country, after provinces. A GIS map (in shapefile format), corresponding to GEO2_ TH1970 can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for Thailand can be found in the IPUMS International Geography variables list. For cross-national geographic analysis on the first and second major administrative level of any country refer to GEOLEV1, and GEOLEV2. More information on IPUMS-International geography can be found here.
Comparability — General
Districts with populations less than 20,000 (based on the most recent sample year) were regionalized (combined) with neighboring districts within the same province to create units with populations greater than 20,000.
There are several unknown districts in the 1970 census microdata. In GEO2_TH1970, several districts are available with their respective codes and all unknown districts are grouped within its province (first administrative level unit) as a separate category.
