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:
GEO1_BD identifies the household's division within Bangladesh in all sample years. Divisions are the first level administrative units of the country. GEO1_BD 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 GEO1_BD can be downloaded from the GIS Boundary files page in the IPUMS International web site.
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 of any country 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.
