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 1990 Ecuador de facto census collected data through face-to-face interviews on housing, household demographics, employment for individuals 8 and older, education, migration, and fertility for women 15 and older. The census day was November 25, 1990. A 10% sample of dwellings from the census (966,234 individuals) is available through IPUMS International at the University of Minnesota. Refer to the IPUMS website for guidelines on citing database versions.
