* Refer to Design Value notes for further details about area design values and/or monitoring periods.

No. of Counties reflects the number of counties in an area, while the total count only counts a county once and doesn't double count the county if it is in more than area.

Multi-state areas are counted in the nonattainment report until all state areas have been redesignated.
