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 2001 United Kingdom de jure census collected data through self-enumeration on the subjects of housing, household demographics, education, and employment. The census day was April 29, 2001.

A 3% sample of dwellings from the census (1,843,525 individuals) is available through IPUMS International at the University of Minnesota. Dwellings, households, and vacant units are not identified in the sample. Refer to the IPUMS website for guidelines on citing database versions.
