Definition
REGNTH indicates the region in Thailand in which the household was enumerated. It is the largest-scale geographic identifier available in the Thailand samples. REGNTH 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.
