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:
MIG2_1_ZM indicates the person's district of residence in Zambia 1 year ago. Migration district codes for MIG2_1_ZM are compatible with codes for GEO2_ZM.
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 for MIG2_1_ZM
are too numerous to list here, but users should be aware that there were changes over time.
The 2010 census did not address the migration question to absent household members.
