Atlanta is only #5? I bet if they broke Atlanta down by area, many neighborhoods (West End, Adair Park, Techwood, etc.) would rank higher than that. Mixing the gentrified ones in with the rest is presenting a false sense of safety.
Several of the high crime areas, such as East Point, Hapeville, etc., are Inside the Perimeter - i.e. Atlanta.
Most of the rest of them seem to be in south Georgia. We drive through Cordelle and Albany on a regular basis. Need to keep an eye out, I guess.
