The Environmental Protection Agency's forthcoming designation of more than 300 counties as "non-attainment" areas for the new ozone air-quality standard is bound to raise public concern that air pollution is getting worse and that it presents a significant health threat. In addition, spring is a time when advocacy groups release "report cards" that give much of the nation a failing grade for air quality. This panel will offer a preview of a forthcoming AEI study "Air Quality in America," which analyzes air quality conditions and trends at the level of individual pollution monitors throughout the nation, offering one of the most detailed pictures of air quality ever produced.
