The National Household Sample Survey (PNAD), established in 1967, collects socioeconomic and demographic information about the Brazilian population. Household and individual questionnaires collect information on housing characteristics, migration, education, employment, and fertility. 

In 2011, the survey removed the food security module and added questions on Internet access, cell phone possession, and marital status. The nationally representative sample covered 146,207 households and 358,919 individuals across 27 federal units and nine metropolitan regions.
