The populations of all of Cobb’s cities grew from 2016 to 2017, but with the exception of Kennesaw, they grew at a slower rate than previous years.
Kennesaw saw the largest percent increase from 2016 to 2017, jumping 1.1 percent from 33,967 to 34,344, followed by Acworth, which grew 0.7 percent from 22,530 to 22,698.
No other city grew by more 0.4 percent from 2016 to 2017, according to the census data.
From 2015 to 2016, Acworth, Marietta, Powder Springs and Smyrna all grew by more than 1.1 percent, while Ausell grew by about 0.8 percent and Kennesaw by about 0.7 percent.
With a 2017 population of 61,048, Marietta remains Cobb’s most populous city. Smyrna is close behind with a 2017 population of 56,685, followed by Kennesaw, Acworth, Powder Springs (15,052) and Austell (7,215), according to the new data.
The new population figures were released by the Census Bureau on Thursday and use a variety of data — housing unit growth, birth rates, death rates, migration data and more — to attempt to estimate the size of cities and counties as of July 1, 2017.
In March, the Census Bureau released estimates for counties that pegged Cobb County’s population at 755,754, up about 0.7 percent from the 2016 estimate of 750,477. The estimate marked the first time since 2010 that Cobb’s growth rate was less than 1 percent.
Over that same period, DeKalb County grew by 0.9, Fulton by 1.7, Gwinnett by 1.5, Paulding by 2.6 and Cherokee by 2.5, according to the Census Bureau.
