Select on a city name to view the rankings for your city, a chart of the trends for ozone and year-round particle levels over time, and infomration about how many residents are in each of the groups most at risk from air pollution. Note that some cities rank high on one list and don’t show up on other lists because of the differences in their pollution problems. Each city includes all the counties that form the economic and transportation network that makes up the metropolitan area as defined by the federal government.
