Answer: 25%
Step-by-step explanation:
For much of the history of Texas, the largest ethnic group were the Anglo Americans who claimed descent from the original 13 colonies. They were mainly drawn there by relatively inexpensive land offered to them by the then Mexican government.
Even though Hispanics are now the largest group in Texas, the Anglo Americans still make up a significant 25% of the population though this has dropped from a 1980 proportion of 27%.
