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_PG identifies the household's district within Papua New Guinea in all sample years. Districts are the second level administrative units of the country, after provinces. GEO2_PG is spatially harmonized to account for political boundary changes across census years. Some detail is lost in harmonization. A GIS map (in shapefile format), corresponding to GEO2_PG can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for Papua New Guinea 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 municipalities have populations less than 20,000, they have been regionalized (combined) with neighboring municipalities.
Boundary changes for GEO2_PG are too numerous to list here, but users should be aware that there were changes over time.
There is no data for North Solomons province in the 1990 sample.
