In the 2010 census, Texas was 70 white. I don’t think it could have dropped 25 points in eight years.
The 70% includes hispanic, which have traditionally been considered white, and only are now considered a separate group because it benefits democrats. But if you go by that split, Texas is 45% white, 37% hispanic, 11% Black, 4% Asian, and some misc and rounding error make up the last few points.
As of the 2010 US Census, the racial distribution in Texas was as follows: 70.4% of the population of Texas was White American; 11.8% African American; 3.8% Asian American; 0.7% American Indian; 0.1% native Hawaiian or Pacific islander only; 10.5% of the population were of some other race only; and 2.7% were of two or more races. Hispanics (of any race) were 37.6% of the population of the state, while Non-Hispanic Whites composed 45.3%.
