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 Mig1_p_za : public Editor {
public:
Mig1_p_za(VarPointer varInfo) : Editor(varInfo) {}
void edit() {

Description
MIG1_P_ZA indicates the person's province of previous residence.
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.
- Between 2001 and 2007 - Parts of North West became Northern Cape.
- Between 2001 and 2007 - Parts of Gauteng became North West.
- Between 2001 and 2007 - Parts of Mpumalanga became Limpopo.
- Between 2001 and 2007 - Parts of Mpumalanga became Gauteng.
- Between 2001 and 2007 - Parts of KwaZulu-Natal became Eastern Cape.
- ~2005: Umzimkulu municipality moved from Eastern Cape to KwaZulu-Natal.
- Between 2007 and 2011, parts of North West became Gauteng
The universe differs significantly between samples. The 2007 census only asked the question of persons who moved since October 2001 and the 2011 census only asked the question of persons who moved after October 2001 -- slightly over 5 and 10 years prior, respectively.
This variable is similar to MIG1_5_ZA for 2001 South Africa, which gives province of residence 5 years prior to that census.
