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_PH1990 identifies the household's provinces within the Philippines in 1990. Provinces are the first level administrative units of the country. A GIS map (in shapefile format), corresponding to GEO1_PH1990 can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for the Philippines 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.
