| Sample design | Representative sample of individuals. | Systematic sample of every hundredth dwelling, after a random start. | Systematic sample of private dwellings. Geographically sorted by population size (municipality and locality) to increase precision. Samples executed independently for each federal entity. | Stratified cluster design; stratified geographically by similar socio-economic characteristics. Clusters are defined as enumeration areas (AGEB). About fifty dwellings within a cluster are included in the sample. Sample fraction depends upon demographic heterogeneity of municipalities. The sample was designed to yield representative statistics for all dwellings. | Stratified cluster design; stratified geographically by municipality and urban area. Clusters are defined as enumeration areas (AGEB), blocks of dwellings or localities. All dwellings within a cluster are included in sample. Sample fraction depends upon demographic heterogeneity of municipalities. The sample was designed to yield representative statistics for all localities with 50,000 inhabitants or more. | Systematic sample of every tenth private dwelling after a random start. Selection was accomplished by a register of private dwellings maintained by INEGI. Where the field worker encountered a building that was no longer occupied, the immediately following occupied dwelling was substituted. | One stage stratified cluster sample by municipality. Enumeration areas (blocks of dwellings within a locality) selected by simple random sampling within strata. |
