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:
GEO3_ZA2007 identifies the household's local municipality within South Africa in 2007. Local municipalities are the third level administrative units of the country, after province and district council (or district/metropolitan municipalities). A GIS map (in shapefile format), corresponding to GEO3_ZA2011 can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for South Africa 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
Local municipalities with populations less than 20,000 (based on the most recent sample year) were regionalized (combined) with neighboring local municipalities within the same district/metropolitan municipalities to create units with populations greater than 20,000.
A few local municipalities in 2007 South Africa are disjointed units and cannot not be regionalized to create a single polygon.
Below is a list of local municipalities that are disjointed:
- Matzikama and West Coast
- Umhlabuyalingana and Umkhanyakude
- All households
