Mableton is the county’s newest and largest city. It incorporated on May 11, 2023, absorbing a much bigger footprint than the old Mableton census-designated place, whose 2020 count was 40,834; measured against Mableton’s new city limits, the 2020 population within that boundary works out to 77,077, ahead of Marietta. Two of the older cities straddle county lines: Acworth extends slightly into Bartow and Cherokee counties, and Austell reaches a short distance into Douglas County, so the figures above are each city’s full population, not just its Cobb County share.<\/p>\n
