Output Area Classification (OAC) is a geodemographic tool offering socio-demographic data for local neighbourhoods.
2001 Output Area Classification
OAC uses key results from the 2001 census to develop the classifications at an output area level. There are three levels to the classification, which includes seven supergroups, 21 groups and 52 subgroups.
The Cambridgeshire Atlas | Output Area Classification (OAC) 2001 displays the seven supergroups and the 21 groups. The 52 subgroups are not displayed in the atlas but the data is available in this download. Using the groups classification adds greater distinction to the atlas.
2011 Output Area Classification
The Cambridgeshire Atlas | Output Area Classification 2011 displays the supergroups, groups and subgroup profiles across the county of Cambridgeshire, which can be filtered to a district, ward and output area level.
It uses key variables taken from the 2011 Census to develop the classifications at an output area level. This 2011 OAC replaces the previous version from 2001. There are now 8 SuperGroups and 26 Groups.
