Where is the best place in the United States to live to avoid air
pollution? The best place to live may depend on whether you or your
family have specific health concerns. People at greater risk from ground-level
ozone are people with lung diseases, such as asthma, and children and adults
who are active outdoors. At greatest risk from particle pollution are people
with heart or lung disease, older adults (possibly because they may have undiagnosed
heart or lung disease), and children. Learn more about how specific health
concerns can affect the comparison. The links above provide health-specific air quality information in terms of the number of unhealthy days based on the Air Quality Index.
