2011 Output Area Classifications (OAC)

OAC is a geodemographic that provides a summary of the built and population characteristics of areas. These groupings are called clusters are derived from 2011 census data. The area classifications are hierarchical classifications, consisting of three tiers: supergroups, groups and subgroups. (Office For National Statistics); and have an open methodology: Gale, C, A. Singleton and P. Longley (2016). “Creating the 2011 area classification for output areas (2011 OAC)”. In: Journal of Spatial Information Science, pp. 1-27.

2011 Output Area Classification by Population Percentage compare to National Distribution

This dashboard presents a comparison of OAC group distribution among regions. For each region, the percentage of population for each OAC group is calculated and then compare with national average to retrieve a score. A score lower than 100 for a region means that the particular group within that region is less than the national average. A score higher than 100 for a region means that the particular group within that region is higher than the national average. For example, a score of 200 for an G group within region R means that the percentage of population within region R classified as group G is 2 times higher than the percentage of population classified as group G across England.

There are 26 groups presented in this dashboard. For more details about each group, see ONS's documentation.
