AHAH Version 2 (Access to Healthy Assets and Hazards)

AHAH (the index of ‘Access to Health Assets and Hazards’) Version 2 is a multi-dimensional index developed by the CDRC for Great Britain measuring how ‘healthy’ neighbourhoods are. It is an updated version of AHAH Version 1 and combines together 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 - Active, Green Space - Passive), and
• Air quality (Nitrogen Dioxide, Particulate Matter 10, Sulphur Dioxide).

Measurement data and deciles for the overall index, 4 domains and 16 inputs are produced for Lower Super Output Areas for England and Wales, and Data Zones for Scotland. All the output datasets are publicly available through the CDRC website under the UK Open Government Licence (OGL).

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