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_ID indicates the household's 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. GEOG2_ID is spatially harmonized accounting 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 GEOG2_ID can be downloaded from the GIS Boundary files page in the IPUMS International web site.
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.
Comparability — General
Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time. Where officially-defined regencies have populations less than 20,000, they have been regionalized (combined) with neighboring regencies.
Boundary changes for GEO2_ID are too numerous to list here, but users should be aware that there were changes over time.
Some provinces and their associated regencies are missing altogether from the data in specific years:
- The province of Aceh in 2005
- All provinces of Kalimantan, Sulawesi, Maluku and Papua in 1995
- East Timor was a province of Indonesia between December 1975 and October 1999. It became independent and separated from East Nusa Tenggara in 1999. Census microdata for East Timor are included in the 1985, 1990, and 1995 samples and coded as "360626000" - the middle 3 digits denoting the ISO country code for present day Timor-Leste.
- All households
- Indonesia: 1971, 1976, 1980, 1985, 1990, 1995, 2000, 2005, 2010
