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:
UPAZILABD identifies the household's upazila (sub-district) within Bangladesh in all sample years. Upazilas are the third level administrative units of the country, after zilas. UPAZILABD is harmonized by name and does not account for boundary changes over time.
The full set of geography variables for Bangladesh 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
UPAZILABD does not account for boundary changes, but users should be aware that there might have been changes over time.
Where officially-defined upazilas have populations less than 20,000, they have been regionalized (combined) with neighboring upazilas within the same zila to create units with populations greater than 20,000.
The following Upazila's are combined for confidentiality purposes:
- Upazila Uttara and Bimanbandar Thana
- All households
- Bangladesh: 1991, 2001, 2011
