Census 2001 Output Area Classification

The 2001 Area Classification of output areas is used to group together geographic areas according to key characteristics common to the population in that grouping. These groupings are called clusters, and are derived using 2001 population census data. This is a new classification produced using the same principles but a different statistical methodology from that used to produce the other area classifications.

This data package presents the data for the 24,140 Census Output Areas in Greater London but data for the UK is also available (see Download URL below).

For further guidance, advice and to see case studies using the 2001 OAC data, visit the OAC User Groups website: http://areaclassification.org.uk/

If you have any queries about or problems accessing any of the data please let Leeds University know: E-mail comments or queries to d.vickers@sheffield.ac.uk or visit their website.

*Please note that the Output Area cluster names (e.g. 'City Living') are not a national statistic and endorsed by ONS, these have been created and added by the University of Leeds to add further meaning to the classification.
