Forsyth County is 10% Asian as of 2015, up from 6% in 2010. Non-hispanic White has dropped from 80% to 75% over this time frame. It's not Gwinnett and it's not as diverse as DeKalb, but it's a surprising change with growth considering its history.
And the demographic change in Forsyth is not evenly distributed through the county. The southern part (which is in CD-7) is diversifying faster than the northern part. This is not to say I expect a D win in 2018, unless there's a huge wave. 2020 may be a decent shot, though.
