**( 2)** The Summary Population Exposure Report is a summary of the population living in an area that is in nonattainment for at least one of the NAAQS. **Area Name:** The "State(s) Area Name" column contains a common or general name for the nonattainment areas on th e row, but may not reflect the exact name of any area on the row. This column cannot be exact since the nonattainment area for one pollutant may not contain the same counties, cities, or states as the nonattainment area for another pollutant on the same row. The abbreviations listed in the "State(s)" column reflect all states identified in row. However, some states on a row may be nonattainment for some pollutants and not for others in the general area. A multi -state area with states that have not all been redesignated to maintenance is counted as a nonattainment area until all of the states in the area are redesignated, with the whole area population displayed.
