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_P_SV indicates the person's municipality of previous residence within El Salvador. Migration municipality codes from MIG2_P_SV are compatible with codes from GEO2_SV.The migration could have occurred at any time in the past.
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. Where officially-defined municipalities have populations less than 20,000, they have been regionalized (combined) with neighboring municipalities.
Boundary changes for MIG2_P_SV are too numerous to list here, but users should be aware that there were changes over time.
