2011 London Output Area Classification

Census Information Scheme

The 2021 London Output Area Classification (LOAC) has been created by the CDRC and published on 2 October 2023. Data and supporting information are on the datastore here.

This page gives access to the OLD 2011 London Output Area Classification (LOAC), an open source geospatial classification, using a combination of over 60 variables from the 2011 Census to classify every small area in London within a hierarchical structure.

The 2011 London classification used the same variables and methodology as the UK 2011 Area Classifications, but provided a finer level of classification for London.

Users can download the LOAC reports and data from this page.

An interactive map of the 2011 LOAC can be found on the CDRC mapmaker website.
