GIS Boundary Files
World map. A world map with national boundaries that match Large Scale International Boundaries (LSIB). LSIB is in WGS84 datum and boundaries reflect U.S. government (USG) policy and not necessarily de facto control. The attribute data in this world map apply to the variables for country of residence (COUNTRY) and country of birth (BPLCOUNTRY). National maps of first and second administrative units nest within the world map.
Spatially harmonized first-level geography. A single world shapefile including the major subnational administrative unit in which the household was enumerated, spanning all IPUMS samples. The attribute data correspond to the codes that are found in the GEOLEV1 variable and enable cross-national and intra-national geographic analysis over time.
Spatially harmonized second-level geography. A single world shapefile including the second level administrative unit in which the household was enumerated, across most IPUMS samples. The attribute data correspond to the codes that are found in the GEOLEV2 variable and enable cross-national and intra-national geographic analysis over time.
Year-specific first-level geography. Individual country shapefiles for the major subnational administrative unit in which the household was enumerated across most IPUMS samples. The IPUMS code in the attribute table matches the corresponding year-specific geography variable.
Year-specific second-level geography. Individual country shapefiles for the second-level administrative unit in which the household was enumerated across most IPUMS samples. The IPUMS code in the attribute table matches the corresponding year-specific geography variable.
Year-specific third-level geography (NEW!). Individual country shapefiles for the third-level administrative unit in which the household was enumerated across selected IPUMS samples. The IPUMS code in the attribute table matches the corresponding year-specific geography variable.
European NUTS geography. The European Union's Nomenclature of Territorial Units for Statistics (NUTS) provides a single uniform breakdown for territorial regions for the European Union countries. The shapefile applies to first (ENUTS1), second (ENUTS2), and third (ENUTS3) NUTS regions.
For additional data tables from population and housing censuses as well as agricultural censuses from around the world refer to the IPUMS IHGIS page.
NOTE: Shapefiles distributed by IPUMS-International provide generalized boundaries and are not intended for precise geographical calculations.
