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:
MIG1_5_ID indicates the person's province of residence five years prior to the census within Indonesia.
Click on the Source Variables tab for information on place of residence for each sample year. Source variables may contain more geographic unit detail but are not suitable for cross-temporal comparison.
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.
Some samples lack full geographic coverage of the country. The 1995 census did not enumerate persons from Kalimantan, Sulawesi, Maluku, or Papua (codes 360061-360094). Therefore, the cases counted represent persons who moved to an enumerated province. The 2005 census did not enumerate persons from Aceh and the interpretation is the same.
It is possible to get the migration information without the merging mentioned above (i.e., the data are not recoded for comparability over time). The unharmonized source variables for each sample retain the original full geographic detail in that year for both province of residence and province 5 years ago.
Some samples also provide information on regency/municipality of residence 5 years ago: see the unharmonized source variables for 1976, 1985, and 1995-2010. Regencies are smaller geographic units than provinces.
For previous province of residence, see MIG1_P_ID.
