- Abstract
- The Clean Air and Health Matrix collates data from a range of health sources including those with a specific clean air focus. The data from each indicator is scored individually at
Lower Social Output Area (LSOA) scale before a weighting is applied and the scores combined The combined scores are then ranked by quintile to provide a list of LSOA's which are deemed
highest priority through to low priority. The indicators include:
- Proximity to Air Quality Management Areas (AQMA's), the closer to an AQMA the higher the score. AQMA's are areas where national legal polution levels are exceeded.
- PM2.5 Concentration - the higher the concentration the higher the score
- Index of Multiple Deprivation 2019 - an indiex taking factors which enable the identification of the most and least deprived LSOA's in the county. The more deprived an area the higher the score.
- ACORN Health "Wellbeing" data - a national dataset where health characteristics of communities is analysed. The more health deprived the lower the score.
- Population number - the larger the population the higher the score
- Number of sensitive receptors to poor air quality - the more receptors (placed in health and educational settings) the higher the score.
- Congestion Hotspots - identified congestion points based on 2015/2016 Traffic Master Teletrac data. The more congested points in an area the higher the score
- Canopy Cover - the lower the canopy cover the higher the score.

- The above indicators used to create the matrix come from a range of sources:
- Proximity to Air Quality Management Areas -DEFRA UK AIR. This is an air information resource (2022).
- PM 2.5 Concentration -DEFRA UK AIR. This is an air information resource which maps data for local Authorities (2018).
- Index of Multiple Deprivation - English Indices of Deprivation 2019. Created by the Ministry of Housing, Communities and Local Government (2019).
- ACORN health "Wellbeing" data -Please see metadata information here. Data created by CACI (2021)
- Population number -Population Mid Year Estimates 2020. Data owned by the Office for National Statistics.
- Number of sensitive receptors to poor air quality - taken from internal GIS datasets and includes HCC owned schools, GP Surgeries, Hospital Sites and pharmacies
- Congestion points -Please see metadata information here.Used data from December 2020, and included Trunk, Primary & Secondary roads and compares average speeds against registered speed limits on approaches to junctions
- Canopy Cover - Tree Canopy Data based on mapped tree data via the Biodiversity Baseline and uses an indicator for lower canopy cover of 15%
