Why Open?

There are many geodemographic classifications available from providers in both the public and private sectors. We do not prescribe any particular classification and always advise user testing and comparison. However, open geodemographics have a number of advantages.

Advantages of Open Geodemographics...

  • Free - to download and use, even for commercial sector applications.
  • Transparent - and reproducible, providing a more defensible position for research and public sector applications.
  • Supported - by an active and helpful user community at no cost.
  • Flexible - and available to modify, augment or replace.

Open Classifications

The following geodemographic products were created with open methods, data and tools by researchers from the University of Liverpool and University College London. Click on a classification to find out more, download the data, view maps or search for you postcode assignment.

OAC

The Output Area Classification (OAC) is a UK geodemographic built partnership with the ONS and is created entirely from the 2011 census data.

LOAC

The London Output Area Classification (LOAC) is a bespoke geodemographic for London following OAC methodology, and developed in partnership with the GLA.

TOAC

The Temporal Output Area Classification (TOAC) is the output from a research project looking at geodemographic change between 2001 and 2011.

Output Area Classification

The Output Area Classification (OAC) is a UK geodemographic built partnership with the ONS and is created entirely from the 2011 census data.

OAC

The OAC geodemographic was created as part of a PhD project at UCL sponsored by the Office for National Statistics. The classification is built at the level of the Output Area / Small Area and is created entirely from 2011 Census data. This work builds on the success of the 2001 version of this classification, and is supported by the OAC User Group.

London Output Area Classification

The London Output Area Classification (LOAC) is a bespoke geodemographic and was developed in partnership with the Greater London Authority.

LOAC

Within a UK context, Greater London has unique built and population structures that are not necessarily described fully by national geodemographic classifications. The LOAC classification methods mirror those used to created OAC, however, is constrained to Greater London. We argue that in the context of London, the results provide additional granularity and insight over UK OAC.

Temporal Output Area Classification

The Temporal Output Area Classification (TOAC) is an output of an ESRC research project looking at geodemographic change between 2001 and 2011.

TOAC

A common criticism of census based geodemographic classifications is that become increasingly out of date during the intercensal period. The Temporal Output Area Classification was created as part of an ESRC research project to explore this issue, and offer mechanisms that enable change can be monitored over time.

TOAC is not meant as a production ready geodemographic and is presented for general interest.

OACUG

The Output Area Classification User Group is a virtual community of users of open geodemographic products. OACUG have previously organised a range of events, training and tools to help support the use of open geodemographics. OACUG is unfunded, and relies on the kind support of volunteers. You can access the OACUG website here.
