What is the annual mean PM2.5 concentration in North Devon?

The population-weighted annual mean PM2.5 concentration in North Devon is 4.66 µg/m3 (DEFRA Pollution Climate Mapping model, 2024). This is below the WHO 2021 annual guideline of 5 µg/m3 and below the UK 2028 interim target of 10 µg/m3.

How is the Gera Air Health Index calculated for North Devon?

For lower-tier local authorities where UKHSA does not publish a separate mortality fraction, GAH equals the PM2.5_score alone (min-max normalised, 4.20 µg/m3 = 10, 10.96 µg/m3 = 0). Full methodology at /methodology/gera-air-health-index.

Where does the air quality data for North Devon come from?

PM2.5 data: DEFRA Pollution Climate Mapping (PCM) model, population-weighted annual mean for 2024, published at uk-air.defra.gov.uk. Both datasets are Open Government Licence v3.0 and reusable with attribution. The Gera Air Health Index is computed by GeraRent from these figures; the inputs are official government data.

Is the air quality in North Devon getting better or worse?

The 2024 figures reflect the most recent DEFRA PCM modelled annual mean. UK PM2.5 concentrations have fallen substantially since 2010 due to emission reductions, but remain above the WHO 2021 annual guideline of 5 µg/m3 in most English local authorities. North Devon (4.66 µg/m3) is one of the few areas that meets the WHO guideline. Gera updates GAH annually when DEFRA publishes new PCM data.
