Latest Census data showed that the population in these four metros increased by more than 400,000 from July 1, 2014, to July 1, 2015. Houston-The Woodlands-Sugar Land and Dallas-Fort Worth-Arlington added about 159,000 and 145,000 residents, respectively—the largest gains of any metro areas in the nation. Austin-Round Rock and San Antonio-New Braunfels were each also among the 16 nationwide to gain 50,000 or more people over the period. These four Texas metro areas collectively added about 412,000 people. Texas as a whole gained about 490,000. No surprise, then, that eight Texas counties were among the 20 counties nationwide that saw the most growth. Those counties were Tarrant, Dallas, Collin, Denton, Harris, Fort Bend, Bexar and Travis.
Five Texas metros—Midland, Odessa, Austin, College Station-Bryan and Houston—were also among the 20 fastest growing between 2014 and 2015.
