More information about this dataset is available here.

Townsend Index#

The Townsend index (1989) is a relative indicator of material deprivation, which has been widely used to identify socio‐economic confounding in crime, education, and health research in England. This dataset is a 2021 version of the Townsend Index Jephcote and Gulliver (2025).
