The State of the Air 2014 shows that the nation’s air quality worsened in 2010-2012, but remains overall much cleaner than just a decade ago.
More than 147.6 million people—47 percent of the nation—live where pollution levels are too often dangerous to breathe, an increase from last year’s report.
Despite that risk, some seek to weaken the Clean Air Act, the public health law that has driven the cuts in pollution since 1970.

• Health Effects of Ozone and Particle Pollution
• Key Findings
  • Ozone Pollution — More than 4 in 10 people lived in areas with unhealthful levels of ozone in 2010-2012. See which cities with the worst ozone had even more unhealthy air days.
  • Year-round Particle Pollution — More than 46.2 million people live in an area burdened year-round by unhealthful levels of deadly particle pollution. See which cities saw continued progress in cleaning up sources and which suffered even more pollution.
  • Short-term Particle Pollution — Many cities endured more days where particle pollution spiked during this period. Fourteen percent (14%) of people in the United States live where they suffered too many days with unhealthful levels of particle pollution.
  • Cleanest Cities — Only four cities made the cleanest list in all three categories, but several were among the cleanest in two.
  • People at Risk — Nearly half of the people in the U.S. live in counties that have unhealthful levels of either ozone or particle pollution. Learn more about people who face the greatest risk—probably someone you know is one of them.
