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:
GEO2_PK identifies the household's administrative division within Parkistan in all sample years. Administrative divisions are the second level administrative units of the country, after provinces. GEO2_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 GEO2_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 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. Where officially-defined departments have populations less than 20,000, they have been regionalized (combined) with neighboring departments.
Boundary changes for GEO2_PK are too numerous to list here, but users should be aware that there were changes over time.
All Pakistan samples exclude the Federally Administered Tribal Areas, Northern Areas (Gilgit-Baltistan) and Kashmir.
