Do 69% of Georgians really live in the Atlanta metro area? I think it’s just slightly over 50%.
It would probably depend on how the Metro area is defined and which counties are included, it seems to vary from source to source.
2019 population estimates:
State of Georgia - 10.6 million
ARC (Atlanta Regional Commission) 10-county region (Cherokee, Clayton, Cobb, DeKalb, Douglas, Fayette, Fulton, Gwinnett, Henry, Rockdale) - 4.6 million
Atlanta-Sandy Springs-Alpharetta MSA (29 counties) - 6.0 million
Atlanta–Athens/Clarke–Sandy Springs CSA (39 counties) - 6.9 million
IMO the MSA feels like the "best" definition of metro Atlanta.
