We provide access to cross-sectional census microdata, these are anonymised individual level records sampled from a single census. They are large individual level files which resemble the sort of data that might be collected directly from a questionnaire. Because individual records contain a wide range of individual and household characteristics, the data enable multivariate analyses for a wide range or purposes.
The UK Data Service holds contemporary data from the 1991 to 2011 Censuses and microdata samples from 1961 onwards are planned.
SAR files are available at four levels, two of which can currently be accessed through the UK Data Service in the same manner as survey data.
