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
- No supplemental programming
- Instructions for interpreting harmonization documents

Comparability — General
Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time. Where officially defined districts have populations below 20,000 (based on the most recent sample year), they have been regionalized (combined) with neighboring districts.
Boundary changes and confidentiality issues:
- Likoma is combined with Nkhata Bay in all sample years for confidentiality reasons.
- Neno was created from Mwanza after 1998.
- The following districts and cities were listed as one district in 1998, but are identified as separate districts in 2008 and 2018:
- Mzimba and Mzuzu City
- Lilongwe and Lilongwe City
- Zomba and Zomba City
- Blantyre and Blantyre City
