Texas has the highest rate of uninsured residents in the nation, according to the U.S. Census Bureau. More than 26 percent of people younger than 65 — 5.8 million Texans — were uninsured in 2010. More than half of those people, 3.8 million, had an annual income less than or equal to 200 percent of the federal poverty line, which was $22,050 for a family of four in 2010.
Counties along the Texas-Mexico border have some of the highest uninsured rates. But nearly half of the uninsured population in 2010 — 2.7 million people — lived in the five most populous Texas counties, which contain Houston, Dallas, Fort Worth, San Antonio and Austin. In Harris County, the most populous county in the state, one of every three residents younger than 65 didn’t have health insurance in 2010.
