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

Description
MIG1_10_ES indicates the person's Community or Autonomous City of residence ten years ago within Spain.
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
The variable is comparable across samples. See MIG1_P_ES, MIG1_1_ES, and MIG1_5_ES for province of previous residence at other time intervals in the past.
The data for 1981 are technically place of residence 10 years and 4 months ago (December 31, 1970).
Several provinces in 1981 are sampled at roughly 5 times the density of other provinces. The weight variables PERWT and WTHH adjust for the 1981 sample design. Statistics generated without using the weights will not be representative of the national population in that year.
Where officially-defined communities and autonomous cities have populations less than 20,000, they have been regionalized (combined) with neighboring communities and autonomous cities.
