North of the metro Atlanta area is north Georgia. Then there’s Metro Atlanta, with east and west Georgia on either side. Central Georgia from just below Griffin to just below Perry, or maybe a little further down. Everything below that is South, except for but the coastal areas are distinguished from the rest of southern Georgia.
