AUSTIN, Texas (AP) — The U.S. Census Bureau says five Texas cities are among the country's top 10 in population gain, and San Marcos is the fastest-growing in the nation for the third consecutive year.

Houston, Austin, San Antonio, Dallas and Fort Worth each added 18,000 to 36,000 people between July 1, 2013, and July 1, 2014. San Marcos saw its population grow 7.9 percent between 2013 and 2014 to almost 59,000 people.

The Census Bureau reports that until this year, Texas was the only state with three cities — Houston, San Antonio and Dallas— with 1 million or more people. California has now joined Texas with that distinction.
