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
MIGRATE0 indicates the person's place of residence 10 years ago. The first digit records movement across major administrative divisions and countries. The second digit reports movement across minor administrative divisions, for samples in which that detail is available.

Comparability — General
This variable is conceptually similar across samples. The data are largely comparable at the first digit: movement between major administrative units or countries. Some samples provide further detail at the second digit, recording movement between minor administrative units.
The major administrative units are provinces in the Philippines, Laos, and Spain and governorates in Iraq. The minor administrative units are municipalities.
The coding for MIGRATE0 corresponds to migration status variables available in other samples: MIGRATE5, MIGRATE1, MIGRATEP, and MIGRATEC. Those variables are conceptually similar to MIGRATE0, but differ in terms of their reference periods.
Comparability — Iran [top]
The major administrative units in this country are province and the minor units are sub province.
Comparability — Laos [top]
The variable records movement between provinces within Laos.
Comparability — Lesotho [top]
The major and minor administrative levels for Lesotho are district and village. If district of residence 10 years ago is identical to district of enumeration, but the response is not "same village" or "same district, different village", then it is classified as "same major administrative unit."
Comparability — Senegal [top]
The major and minor administrative levels for Senegal are region and department.
Comparability — Spain [top]
The major and minor administrative levels for Spain are province and municipality.
The universe for 2001 differs from 1991. The 2001 sample excludes persons who did not reside in the household at the time of the census.
Comparability — Tanzania [top]
The variable records movement between regions within Tanzania.
Comparability — Trinidad and Tobago [top]
The variable records movement between regions in all years and between communities within regions in 2011. Persons who were abroad 10 years ago are likely coded to "unknown" in 1990 and 2000.
Comparability — Zimbabwe [top]
The major and minor administrative levels for Zimbabwe are province and district.
