Explore how IPUMS created this variable
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:
- Harmonization table
- Supplemental programming
- Instructions for interpreting harmonization documents

Description
MIG2_5_BR indicates the person's municipality of residence 5 years ago within Brazil. Migration municipality codes from MIG2_5_BR are compatible with codes from GEO2_BR.
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
See also MIG2_P_BR for municipality of previous residence in 1980, 1991, and 2010. For the country of residence 5 years ago of international migrants, see MIGCTRY5 (Country of residence 5 years ago).
Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time. Where officially-defined municipalities have populations less than 20,000, they have been regionalized (combined) with neighboring municipalities.
Boundary changes for MIG2_P_BR are too numerous to list here, but users should be aware that there were changes over time.
