Relying significantly on lower-wage jobs to fuel growth, Texas has drawn from a large, relatively cheap labor pool that’s included large numbers of legal and illegal immigrants. Illegal immigrants have taken jobs in many of the industries central to Texas’ economic boom, such as home construction, agriculture and the service industry. Illegal and legal immigrants make up about 20 percent of the state’s total workforce, according to the U.S. Census Bureau. And the Pew Hispanic Center estimates that 8 percent of Texas’ total workforce was made up of illegal immigrants as of 2008.
