Topic summary
Texas Triangle
The Texas Triangle is one of eleven megaregions of the United States, located entirely within Texas, containing the state's five largest cities (Dallas–Fort Worth, Greater Houston, San Antonio–Austin), and home to about two-thirds of the state's population, being connected by Interstate 45, Interstate 10, and Interstate 35.
In 2004, the Texas Triangle contained five of the 20 largest cities in the U.S. and was home to over 70% of all Texans, with a population of 13.8 million. In 2025, its population reached nearly 23 million, following rapid growth across much of Texas. In 2009, Kent Butler and Fritz Steiner projected that, by the mid-21st century, its population was expected to increase by around two-thirds, or 10 million people, comprising nearly 80% of all Texans.
Additional metropolitan areas in the region include Bryan–College Station, Killeen–Temple–Fort Hood, and Waco. Twelve micropolitan statistical areas are within the Triangle, which includes 66 counties. Beaumont, located east of Houston, has been considered part of the Texas Triangle by numerous studies dating from 2000. Burleson County is the center of the Texas Triangle.
