GEO1_MX identifies the household's state within Mexico in all sample years. States are the first level administrative units of the country. GEO1_MX is spatially harmonized accounting for political boundary changes across census years. Some detail is lost in harmonization; see the comparability discussion. A GIS map (in shapefile format), corresponding to GEO1_MX can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for Mexico can be found in the IPUMS International Geography variables list. For cross-national geographic analysis on the first and second major administrative level of any country refer to GEOLEV1, and GEOLEV2.
