The fact that Georgia's fastest growing city is in Gwinnett County isn't all that surprising — but which one took the crown may be.

According to new population estimates released Thursday by the United States Census Bureau, the city of Grayson gained 346 residents between 2014 and 2015. While it doesn't sound like much, the growth represents a 13.1 percent change — the largest year-over-year increase seen by any Georgia city.

Grayson's current population is estimated at 3,147.
