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:
GEO2ALT_CL identifies the household's department within Chile in 1960 and 1970. Departments are the second level administrative units of the country, after provinces. GEO2ALT_CL 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 GEO2ALT_CL can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for Chile 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
Chile reorganized administrative divisions between 1970 and 1982, GEO2_CL reflects municipalities in Chile from 1982 to 2002 samples.
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 GEO2ALT_CL are too numerous to list, but users should be aware that there were changes over time.
