Step 1: Investigate the problem

Find out who is most at risk in your city

In every city, some individuals and neighborhoods face greater health risks from air pollution than others due to differences in exposure and susceptibility. This section provides resources to help identify which neighborhoods in your city are most exposed to high levels of air pollution and who in your city is most at risk of negative health consequences driven by poor air quality. This information can help your city or town design targeted actions that reduce disparities, support sensitive populations and get the most health and economic benefits out of clean air policies.
