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_IR2006 identifies the household's sub-province within Iran in 2006. Sub-provinces are the second level administrative units of the country, after divisions. A GIS map (in shapefile format), corresponding to GEO2_IR2006 can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for Iran 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

The following sub-provinces were combined for confidentiality purposes:
- Ashtian is combined with Tafresh.
- Abumusa is combined with Qeshm.
