Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
GEO2_IDX indicates the regency (kapupaten) within Indonesia in all sample years. It is also known as municipality (kotamadya). The difference between regency and a municipality is dependent on the population density of the geographical unit. A primarily rural area would be known as regency and a primarily urban area would be known as a municipality. Regencies/municipalities are the second level administrative units of the country, after provinces. GEO2_IDX is harmonized by name and does not account for boundary changes over time.
The full set of geography variables for Indonesia 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.
At the present moment, IPUMS International is only releasing integrated geography for the first level of geography for Indonesia. Year specific geography and maps along with variables that are spatially harmonized at the second level of geography and account for political boundary changes across census years will become available in the near future.
