2024 American Lung Association State of the Air Report
Nearly 263 million people live in the 885 counties with enough monitoring data to be assigned a grade for at least one pollutant in this year’s report. The majority of U.S. counties actually don’t have monitors—which means that many communities, especially rural ones, don’t have official monitored information on their air quality. It is important to note that the population numbers included in this section are only for those places that collect air pollution data, and do not reflect the entire population of these groups in the U.S. The availability of data, and hence the population that is included in this report, differs for each pollutant.
What's the State of Your Air?
For 25 years, the American Lung Association has analyzed data from official air quality monitors to compile the State of the Air report. The more you learn about the air you breathe, the more you can protect your health and take steps to make the air cleaner and healthier.
