An external partner, University College London is currently working on producing an updated 2011 Census Output Area Classification for the UK using 2011 Census data. It is currently planned that the 2011 Output Area Classification will be published in late 2013.
When the methodology used for producing the 2011 Output Area Classification has been finalised, ONS will then look to update the current 2001 Census based UK area classifications for Super Output Areas/Data zones, local authorities, and health areas using 2011 Census data. These updates are planned to be published in 2014. Consideration will also be given to updating the previous ward area classification.
As part of the methodology review for a new Output Area Classification, thought will be given to periodically updating the 2011 Census based area classifications in the future using non-census data sources.
