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_ID identifies the household's province within Indonesia in all sample years. Provinces are the first level administrative units of the country. GEO1_ID 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 GEO1_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.
Boundary changes and confidentiality issues:
- East Timor was a province of Indonesia between December 1975 and October 1999. It became independent and separated from East Nusa Tenggara in 1999.
- In 1999, North Maluku split from Maluku.
- In 2000, Bangka Belitung split from South Sumatra; Banten split from West Java; and Gorontalo split from North Sulawesi.
- Kepulauan Riau was created from Rieu in 2002 though it does not appear in the samples until 2005.
- Papua Barat was created from Papua in 2003, though it does not appear in the samples until 2010.
- In 2004, Sulawesi Barat was created from Sulawesi Selatan although changes do not appear on maps until 2010.
Missing provinces: Some provinces are missing altogether in specific sample 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 "360626" - the last 3 digits denoting the ISO country code for present day Timor-Leste.
- All households
- Indonesia: 1971, 1976, 1980, 1985, 1990, 1995, 2000, 2005, 2010
