According to Steve H. Murdock, a demographer with the Hobby Center for the Study of Texas at Rice University and a former director of the U.S. Census Bureau, the White American population is aging, while minority populations remain relatively young. As of 2011, according to Murdock, two out of three children in Texas are not non-Hispanic Whites. Murdock also predicted that, between 2000 and 2040 (assuming that the net migration rate will equal half that of 1990-2000), Hispanic public school enrollment will increase by 213 percent, while non-Hispanic white enrollment will decrease by 15 percent.
