I would suggest using Google or Bing to gather information about the 30314 zip code and specify which area of that zip code you are interested in. The zip code covers a large area and a solution to your inquiry would require additional details.
You might start with a Google search. Enter the service you want followed by the zip code, and you will get pretty good results. For employment, go to your favorite employment website and search by zip code. For transit, check out itsmarta.com. Good luck!
