As Texas' population surged by 1.8 million people from 2010 to 2014, the state's suburban population growth outpaced growth in major metropolitan areas, census figures show.

New estimates released Thursday by the U.S. Census Bureau spotlighted the fastest-growing areas of Texas that are supporting projections that the state's population will double by 2050.

Among Texas cities with a population larger than 50,000, San Marcos ranked as the fastest-growing. Its population grew by 31 percent from 44,894 in 2010 to 58,892 in 2014, making up almost a third of the population of Hays County, which is among the fastest-growing U.S. counties.

Nationally, San Marcos was ranked as the fastest-growing city in the nation for the third consecutive year.

Houston, San Antonio and Dallas maintained the same spots on the list of 10 largest cities in the U.S.

But Texas is also home to the fastest-growing large cities in the country. Austin was the fastest-growing city among those with a population larger than 500,000, growing by 15.5 percent from 790,390 in 2010 to 912,791 in 2014.

California tied with Texas for the greatest representation on the list of 10 U.S. cities with a population exceeding 1 million, with Los Angeles, San Diego and San Jose joining Houston, San Antonio and Dallas.
