#About This is the repository for the Temporal Output Area Classification (TOAC) that was created as part of an ESRC grant looking at geodemographic change between 2001 and 2011.
The code used to develop the classification and the final lookup for 2011 Output Areas and a 2001 - 2011 classification are available to download above.
