We provide access to census microdata, which are individual level data. Large samples of census records have been drawn and anonymised and are known as the Samples of Anonymised Records (SARs).
We hold data from the 1991 and 2001 Censuses and SARs from the 2011 Census are anticipated. SARs are very large multivariate datasets that contain a wealth of flexible information for social scientists and policy makers.
Access census microdata
SAR files are available at three levels, two of which can be accessed through the UK Data Service in the same manner as survey data.
End User Licence data are available to registered users who have agreed to the licence conditions. Overseas applications must be approved by the data depositors.
The key analysis datasets are;
Additionally, specialist datasets for users interested in imputation are available for 2001. These are larger files as they contain an imputation flag variable for each original variable. As they are otherwise identical, general users are advised to user the smaller standard files.
The 2001 household file is available under Special Licence; users must be approved researchers in order to access this file.
Users should also be aware that there are also more detailed versions of the data available only within an Office for National Statistics safe setting. Applications to use these data as an approved researcher should be made directly to the Office for National Statistics.
