Air Quality


Description: Air quality can serve as a proxy for environmental quality in general. While there are many aspects of environmental quality to consider, air quality has been shown to be highly correlated with other environmental measures such as water quality, tree canopy, and health issues related to environmental problems.

Performance Measure: Percent of Days with Good or Moderate Air Quality Index – measures the percent of days within a calendar year when the air quality was reported as being either moderate or good. Learn more about outdoor air quality data.

Data: Air Quality Index Report

Interpretation: The air quality index in Fairfax County has remained at or above 98% over the past five years indicating good environmental quality thereby supporting the health of county residents.
