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_CL indicates the person's province of residence in Chile five years prior to the census. The data, 1982 to 2002, are coded into the modern geographic classification of provinces.
See MIG1ALT_5_CL for a comparable variable that codes the 1970 sample into the pre-1974 geographic classification of provinces. See also MIG1ALT_P_CL for a similar variable on province of prior residence for 1960, which also uses the pre-174 geography.
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 officially-defined provinces have populations under 20,000, they have been regionalized (combined) with neighboring provinces.
The following units are combined for confidentiality reasons:
- Parinacota is combined with Arica for confidentiality reasons.
- Isla de Pascua is combined with Valparaíso for confidentiality reasons.
- Palena is combined with Aisén for confidentiality reasons.
- Capitan Prat and General Carrera are combined with Ultima Esperanza for confidentiality reasons.
- Antartica Chilena and Tierra del Fuego are combined with Magallanes for confidentiality reasons.
MIG1_5_CL is comparable for 1982-2002.
In 1974, the Chilean government decentralized the administrative regions of its country, and many province boundary and names were changed. It was not possible to recode the less-detailed pre-1970 system into the more-detailed modern system.
