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_PK identifies the household's province within Pakistan in all sample years. Provinces are the first level administrative units of the country. GEO1_PK 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_PK can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for Pakistan 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
All Pakistan samples exclude the Federally Administered Tribal Areas, Northern Areas (Gilgit-Baltistan) and Kashmir.
Around 1990, the spelling of Baluchistan changed to Balochistan and Sind changed to Sindh. However, the changes in the two names have been reflected in the 1981 sample.
Where officially-defined provinces have populations under 20,000, they have been regionalized (combined) with neighboring provinces.
