Census: Hays and Comal County tied for fourth fastest-growing counties in U.S.

Populations of cities, towns, and counties in the South and West regions of the United States still experienced the most growth from July 2020 to July 2021, with the top 15 fastest-growing cities or towns located in these regions, according to new population estimates for cities and towns, released by the U.S. Census Bureau today.

The fastest-growing county was Rockwall County, Texas, which increased by 6.5% between July 1, 2020, and July 1, 2021, followed by Chambers County, Texas (5.7%); Jasper County, South Carolina (5.4%); Hays and Comal counties in Texas, and Morgan County, Georgia (5.2%) were tied for fourth fastest growing, followed by Fort Bend County (5.1%); and Long County, Georgia (5.0%).

Eight of the 15 fastest-growing large cities or towns by percent change were in the West — with five in Arizona — and seven in the South. The South and West also contained the top 15 cities with the largest numeric gains — 11 in the South and four in the West.

“While only 4% of all cities and towns had a population of 50,000 or more in 2021, collectively they contained 129.3 million people — nearly 39% of the U.S. population,” said Crystal Delbé, a statistician in the Population Division at the Census Bureau. “On the other hand, of the 19,494 incorporated places in the United States, more than 75% had fewer than 5,000 people.”

Top Places for Population Growth

Arizona, Texas, Florida, and Idaho all had several places among the 15 fastest-growing cities or towns:

• Georgetown, Texas, had the largest growth from July 2020 to July 2021, increasing by 10.5%, a rate of growth that would double the population in less than seven years.
• Georgetown was followed by Leander, Texas (10.1%); Queen Creek Town, Arizona (8.9%); Buckeye, Arizona (8.6%); and New Braunfels, Texas (8.3%).
