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
class Mig2_1_mw : public Editor {
public:
Mig2_1_mw(VarPointer varInfo) : Editor(varInfo) {}
void edit() {
long a = getRecoded();
switch (dataSet) {
case dataset_id::mw1987a: {
if (MW1987A_0411() == 98000)
a = GEO2_MW(0);
} break;
}
setData(a);
}
};
Description
MIG2_1_MW indicates the person's traditional authority (TA) of residence 1 year ago within Malawi. Migration traditional authority codes from MIG2_1_MW are compatible with codes from GEO2_MW.
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_MW are too numerous to list here, but users should be aware that there were changes over time.
To match geography from earlier time periods, several district's traditional authorities are coded together:
- Machinga and Balaka
- Mulanje and Phalombe

- Persons age 1+
Availability
