The Atlanta Regional Commission (ARC) is the regional planning and intergovernmental coordination agency for the 10-county Atlanta area, including Cherokee, Clayton, Cobb, DeKalb, Douglas, Fayette, Fulton, Gwinnett, Henry and Rockdale counties, as well as the City of Atlanta.
ARC also produces and collects data for a larger, 20-county area for air quality purposes. These include the 10 counties above, plus Barrow, Bartow, Carroll, Coweta, Forsyth, Hall, Newton, Paulding, Spalding and Walton counties.
So, the Atlanta region is defined in many different ways. This map (PDF) may help clear things up.
