Annual Particle Pollution

This indicator gives a grade to each county in the U.S. based on the average annual number of days that exceed U.S. particle pollution standards (PM2.5). The American Lung Association (ALA) assigns grades A-F to counties (A=1; B=2; C=3; D=4; F=5), based on number of days that particle pollution exceeded US standards during the three year measurement period. The five-point grading scale was used for the distribution (Green = <2; Yellow = 2 - 3; Red = >3). The air quality data is collected by the EPA and summarized by the ALA.
