Methodology

All data was taken from IQ Air’s 2019 World Air Quality Report, for England, Wales and Scotland. The data from IQ air was provided per town, city, and village in England, Wales and Scotland. We focused on the areas that were ranked as meeting the WHO target, or as ‘good’ by WHO. We then filtered each of the best towns/cities/villages by region and submitted this data into the tool.

The air pollution level is ranked by PM2.5 (fine particulate matter) data as acquired from ground-based air quality monitoring stations with high data availability, and is in units of µg. The official ranking is as follows:
   • 0-10 µg: WHO target
   • 10-12 µg: Good
   • 12.1 – 35.4 µg: Moderate
   • 35.5 – 55.4 µg: Unhealthy for sensitive groups
   • 55.5 – 150.4 µg: Unhealthy
   • 150.5 to 250.4 µg: Very unhealthy
   • 250.5 µg +: Hazardous
