Roanoke, Trophy Club and Westlake also saw slight gains while Keller declined in population, according to the data.
The latest Census estimates offer a look at how populations have changed across the country since the start of the pandemic in March 2020.
Fort Worth saw a 1.87% increase in population and was ranked as the nation's 13th most populous city, data showed. Estimates from June 2021 had ranked Fort Worth as the 12th most populous ahead of Jacksonville, Florida. But the estimates released May 26 show Jacksonville with more residents in the 2020 census as well as in the July 2021 estimate.
Westlake added about 51 residents, for a gain of 3.13%, data showed. Roanoke added about 231 residents, for a 2.39% increase in estimated population. And Trophy Club added about 83 residents, for a 0.61% gain, according to population estimates.
The estimates showed Keller lost about 395 residents, which was a 0.86% decline, the data showed.
Across the nation, cities in the south and in the west saw more population gains than other regions of the U.S., according to the bureau.
The central Texas cities of Leander and Georgetown saw the largest percentage gains in the nation between the April 1, 2020, census and estimates from July 1, 2021, according to the Census data. Leander grew 13.1%, and Georgetown grew 12.6%, data showed.
“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, in a news release. “On the other hand, of the 19,494 incorporated places in the United States, more than 75% had fewer than 5,000 people.”
