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_5_ec : public Editor {
public:
Mig1_5_ec(VarPointer varInfo) : Editor(varInfo) {}
void edit() {
long a = getRecoded();
switch (dataSet) {
case dataset_id::ec1990a: {
if (AGE() < 5)
a = 218099;
} break;
}
setData(a);
}
};
Description
MIG1_5_EC indicates the person's province of residence in Ecuador five years prior to the census.
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
MIG1_5_EC is only available for the 1990, 2001, and 2010 censuses.
Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time.
Boundary changes and confidentiality issues:
- Sucumbios was created in 1989 and Orellana was created in 1998; both units were formed from the province of Napa.
- In 2007 two new provinces were created: Santo Domingo de los Tsáchilas formed form Pichincha and Santa Elena from Guayas.
- Galapagos Islands are combined with Guayas for confidentiality reasons.
