    dct:description """This page contains older versions of the AHAH data product. The most recent version can be viewed at a link below.\r
\r
AHAH (the index of ‘Access to Health Assets and Hazards’) is a multi-dimensional index developed by GeoDS for Great Britain measuring how ‘healthy’ neighbourhoods are. \r
\r
The AHAH index combines indicators under four different domains of accessibility:\r
\r
* Retail environment (access to fast food outlets, pubs, tobacconists, gambling outlets),\r
* Health services (access to GPs, hospitals, pharmacies, dentists, leisure services),\r
* Physical environment (Blue Space, Green Space - Passive, Green space - active), and\r
* Air quality (Nitrogen Dioxide, Particulate Matter 10, Sulphur Dioxide) (domain added\r
\r
## Content\r
\r
Measurement data and deciles for the overall index, 3 or 4 domains and 14 or 15 inputs are produced for Lower Level Super Output Areas (LSOAs) for England and Wales, and Data Zones (DZ) for Scotland. Column headings have been standardised across all versions. As a result there is some variation between the column headings defined in the source code and in the datasets. Please consult the relevant Variable Dictionary for full details.\r
\r
## Quality, Representation and Bias\r
\r
The data are from multiple data sources. Each were selected following review since they presented the best quality or low bias data sources. We checked individual data sources for bias using local checks, however we did not find any issues. All external datasets are validated by their data producer as well.\r
\r
## Version History\r
\r
Version 5 (on a different record) was updated including the most up-to-date data (released ealy 2026). AHAH Version 4 (released 2024), Version 3 (released 2022), Version 2 (released 2017) and Version 1 (released 2016) are here.""" ;
