Access to Healthy Assets & Hazards (AHAH)

AHAH (the index of ‘Access to Health Assets and Hazards’) is a multi-dimensional index developed by the CDRC for Great Britain measuring how ‘healthy’ neighbourhoods are. Version 3 is updated including the most up-to-date data for 2022. The AHAH index combines indicators under four different domains of accessibility:

  • Retail environment (access to fast food outlets, pubs, off-licences, tobacconists, gambling outlets),
  • Health services (access to GPs, hospitals, pharmacies, dentists, leisure services),
  • Physical environment (Blue Space, Green Space - Passive), and
  • Air quality (Nitrogen Dioxide, Particulate Matter 10, Sulphur Dioxide).

Measurement data and deciles for the overall index, 4 domains and 15 inputs are produced for Lower Level Super Output Areas (LSOAs) for England and Wales, and Data Zones (DZ) for Scotland.

An online map of AHAH domains and the overall index for the whole of Great Britain is available through the CDRC interactive web mapping tool - see link below.

AHAH Version 2 which covers 2017 is also included in the data downloads.
AHAH Inputs/Components (v3) are included in the main download file
