Dallas-Fort Worth population still booming

Texas — and specifically North Texas — saw some of the biggest population increases nationwide last year.

The big picture: The Lone Star State has six of the country's top 10 fastest-growing counties by percentage and eight of the top 10 counties with the largest numeric growth, per a new U.S. Census Bureau report .

• Denton has become the seventh Texas county to have a population over 1 million, after adding nearly 30,000 residents last year.

Why it matters: Dallas-Fort Worth continues to see a massive influx of new residents , with many people moving to the suburbs and exurbs.

• Kaufman was again the fastest-growing county in the country, followed by Rockwall County.

The latest: Collin, Denton and Tarrant counties were among the top 10 counties nationwide to add the most people between July 2022 and July 2023 — adding nearly 94,000 residents total.

• Collin and Denton were the top two, with Collin adding 36,364 people and Denton adding 29,943.

Of note: This data is the most recent release of the annual Population Estimates Program , which estimates the population between censuses.

• The program uses administrative records and other sources to calculate annual changes in population and housing.

Reality check: People are still moving out of Dallas proper .

• More than 34,000 Dallas County residents moved away in 2023, up from the nearly 19,000 departures in 2022, per the Census report.

The bottom line: Despite that trend, Dallas County remains one of the most populous counties in the country, ranking eighth with more than 2.6 million residents.

• And, it was third in the country for natural population increases, adding 19,550 babies. Tarrant County ranked fifth with 13,010 babies.
