Definition
GEO1_THX identifies the household's province (Changwat) within Thailand in all sample years. Provinces are the first level administrative units of the country. GEO1_THX is harmonized by name and does not account for boundary changes over time.
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 refer to GEOLEV1, and GEOLEV2. More information on IPUMS-International geography can be found here.
At the present moment, IPUMS International is only releasing integrated geography for the first level of geography for Thailand. Year specific geography and maps will become available in the near future.
