The UK Data Service Census Support service is responsible for online registration (via EASE) for access to the UK Census datasets by the academic community. The site is a one-stop registration site for contemporary decennial Census datasets (1971-2011):

  • UKBORDERS - contemporary and historical digital boundary map data (EDINA)
  • Travel to work and Migration (origin/destination) statistics (Centre for Interaction Data Estimation and Research)
  • Samples of Anonymised Records (i.e. microdata) - Each file is a sample of anonymised individual person- or household level records drawn from the census database, containing a range of socio-demographic characteristics for respondents, with a particular emphasis on either individual, household, or geographical detail. Each file contains data from one census only. Sample sizes range from 1% to 10%, and determine the variable and geographic detail available. Registration with the UK Data Service is required. The Teaching Files are unrestricted 1% samples of microdata containing limited detail and are available for England and Wales, Northern Ireland, and Scotland from the 2011 census; these three files may be downloaded without registration.
