The Texas Triangle is a region of Texas that contains the state's five largest cities and is home to the majority of the state's population. The Texas Triangle is formed by the state's four main urban centers, Austin, Dallas-Fort Worth, Houston, and San Antonio, connected by Interstate 45, Interstate 10, and Interstate 35. In 2020, the population of the Texas Triangle reached nearly 21 million following rapid growth across much of Texas.[1] The Texas Triangle is one of eleven megaregions in the United States, clusters of urban areas that share economic and cultural ties.
In 2004, the Texas Triangle contained five of the 20 largest cities in the U.S. and was home to more than 70% of all Texans, with a population of 13.8 million.[3] In the next 40 years, the population of the Texas Triangle is projected to increase by more than 65%,[4] or 10 million people, and comprise 78% of all Texans.
