Censuses provide population numbers, household or family size and composition, and information on sex and age distribution. They often include other demographic, economic and health-related topics as well. The 1980 Brazil de jure census collected data through face-to-face interviews and self-enumeration on housing conditions, family composition, income, educational attainment, employment for those 10 and older, migration, and fertility for women 15 and older. The census day was September 1, 1980 and fieldwork continued until December 1. A differentially weighted sample of 5% of households from the census (5,870,467 individuals) is available through IPUMS International at the University of Minnesota.
