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 1991 Greece de facto census collected data through face-to-face interviews on the subjects of housing, household demographics, education, fertility, family businesses, and employment. The census day was March 17, 1991. A 10% sample of households from the census (969,407 individuals) is available through IPUMS International at the University of Minnesota. Refer to the IPUMS website for guidelines on citing database versions.
