Final answer:
The percentage of Hispanics in the U.S. population is expected to increase, while the percentage of non-Hispanic whites is expected to decrease.
Step-by-step explanation:
The U.S. Census Bureau projects that by mid-century, the percentage of Hispanics (of any race) in the U.S. population will increase, while the percentage of non-Hispanic whites will decrease. According to the Bureau, whites comprised 78% of the population in 2012, but this is projected to decline to 69% by 2060. In contrast, the proportion of U.S. citizens who are of Hispanic background is expected to rise substantially.
