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 Mig1_p_eg : public Editor {
public:
Mig1_p_eg(VarPointer varInfo) : Editor(varInfo) {}
void edit() {
long a = getRecoded();
switch (dataSet) {
case dataset_id::eg2006a: {
if (EG2006A_0425() == 99 && EG2006A_0401() == 11)
a = 818099;

setData(a);
}
};
Description
MIG1_P_EG indicates the person's governorate of previous residence in Egypt. Migration could have occurred at any time in the past.

Comparability — General
Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time.
Boundary changes:
- The boundary between Menoufia and Behera governorates changed between 1986 and 1996.
- The governorate of 6th October City received its own code in 2006. It subsequently split from Giza in 2008.
- The governorate of Helwan received its own code in 2006. It subsequently split from Cairo in 2008.
- Upon splitting Helwan and 6th October City, the boundary between Giza and Cairo changed.
- Luxor and Qena are combined in MIG1_P_EG. Luxor was created from Qena in 2009
.
Missing geography:
- The 1986 sample is missing Luxor governorate and its corresponding districts.
This question was asked of all persons in the 1986 and 1996 sample, but only of non-visitors in 2006.
In 1986 sample, a higher proportion of persons (relative to 1996 and 2006) declared as place of previous residence the same governorate where the household was located at the time of the census. In order to identify these cases, users could compare governorate of previous residence to the governorate where the household is located (refer to GEO1_EG).
