Though it’s now home to copious ethnic businesses peppered with flyers in languages from Spanish to Korean, Gwinnett was a predominantly white, Republican stronghold a couple of decades ago, where Democrats ran unsuccessfully, if at all. But the county stunned the rest of the state in 2016 when Democratic presidential nominee Hillary Clinton won the [county], early evidence of Georgia’s swing-state ascendancy.

Census data shows why. Gwinnett’s white-only residents declined by over 30 percent from 2000 to 2020, while its Black, Hispanic and Asian populations saw substantial increases. Many were transplants that came for affordable housing and jobs. Democrats capitalized on that transition by promoting voter registration and translating information into other languages.[Link]
