Explosive growth makes Gwinnett among nation’s fastest-growing counties

Gwinnett remains one of the fastest-growing counties in the nation, adding 90,499 residents in five years, new population estimates by the U.S. Census Bureau show.

That’s an 11.2 percent increase – enough to land Gwinnett at No. 83 on the bureau’s list of the 100 fastest-growing counties in the country from 2010 to 2015. The list includes only counties with at least 10,000 residents.

Four other Georgia counties also made the list: Long County, which grew 22.7 percent, was the nation’s seventh-fastest growing county. Forsyth County grew 21 percent and finished at No. 11. Bryan County (16.2 percent, No. 27) and Columbia County (16.1 percent, No. 28) also made the list.

The fastest-growing county in the country this decade: Williams County, N.D., which grew a whopping 57.6 percent, but which has only 35,294 residents. Here's the complete list.

Gwinnett has long been one of the nation’s fastest-growing counties. It began to transform from a rural enclave to a suburban juggernaut in the 1970s.

As The Atlanta Journal-Constitution reports, the new population estimates show the metro area now is home to more than 5.7 million residents. Fulton County passed the one-million mark and remains Georgia's largest county.

Gwinnett is the state’s second-largest county, reaching 895,823 residents in 2015, according to the Census Bureau.
