Metro Atlanta's population will jump 25 percent over the next 15 years, according to a new analysis of the region's growth.

Overall, the population of the Atlanta metro area will jump by 25 percent from 2015 to 2030, according to a LawnStarter analysis of projections from the Governor's Office of Planning and Budget. During that period, the region is anticipated to gain 1.4 million residents. That's equivalent to the number of people who live in the entire Jacksonville, FL, metro area.

From 2014 to 2015, Forsyth County, GA, ranked as the fastest-growing county in the Peach State and the 11th fastest-growing county in the U.S. Based on figures from the U.S. Census Bureau and the Georgia Governor's Office of Planning and Budget, the population of Forsyth County is projected to climb 58 percent from 2015 to 2030. That growth rate would be the highest during that period for any of the 29 counties in the federally designated Atlanta metro area.
