A lot of times they do this to isolate voters in one district. You make 1-2 compact districts like GA-5, that contains a large number of Democratic voters (and black people), like 90% margin. Then you surround it with gerrymandered districts and make them nearly but not quite competitive, like 55% Republican white suburban. Thus the same population of Republicans can have 4 or 5 districts while the Democrats get 1 or 2.
