Gwinnett
Gwinnett County is not Atlanta. It's not far, and depending on traffic, the trip isn't too long, but it's not in Atlanta, it's not the same neighborhood. Memphis, TN is certainly not Atlanta. So nobody from Memphis or Gwinnett county would say they were an Atlanta native because it would be false. Most people from Memphis or Gwinnett would say they were from Memphis or Gwinnett, and they would be happy enough with where they were from and who they were that they wouldn't feel a need to say they were an Atlanta native.
Example:
A poser is someone who is not who they say they are, and most people don't want to be known as a poser, so they tell people where they're really from when someone asks, since it's hard to trust somebody who would think of lying about something as seemingly harmless as where you were from or what your favorite color was as something everybody does all the time. Most people don't look to benefit from saying their favorite color or where they are from or who they are is something different than what it really is. Gwinnett is different than Atlanta, just like green is different than blue. People who want/choose to live in Gwinnett have their reasons, just like people who want/choose to live in Atlanta have theirs, but to try and say you live in Atlanta when you live in Gwinnett to gain something is no good. It would be like a business based in Atlanta having a Gwinnett address that didn't exist while people were sending money there, thinking it was a legitimate business.
