For the third year in a row, San Marcos has been named the fastest-growing city in the U.S. According to new data released by the U.S. Census Bureau, the city's population grew 7.9 percent between 2013 and 2014, to 58,892.
San Marcos isn't the only Austin suburb whose population is booming. Georgetown ranked No. 2, with a population growth of 7.6 percent (54,934 total residents). And New Braunfels ranked No. 13, with a population growth of 4.8 percent. Three other Texas cities were among the fastest-growing by percentage: Frisco (No. 4), Conroe (No. 6) and McKinney (No. 7).
The Lone Star State's big cities saw tons of growth as well. "Half of the 10 cities with the largest population gains between 2013 and 2014 were in Texas," notes the Census Bureau.
