Final answer:
The racial or ethnic groups expected to increase as a percentage of the U.S. population are Hispanics and Asians, while non-Hispanic whites are projected to decrease. Hispanics, in particular, are predicted to see a substantial rise.
Step-by-step explanation:
The racial or ethnic groups in the United States expected to increase in terms of percentage of the population over the next few decades are Asians and Hispanics. The U.S. Bureau of the Census projects that non-Hispanic whites will decrease from 78% of the population in 2012 to 69% by 2060. Meanwhile, the proportions of Hispanics and Asians are predicted to rise substantially. This increase is also reflected in the changing composition of the workforce, as greater diversity is seen with the rise of not only racial and ethnic minorities but also with women who entered the workforce in the 1970s and 1980s now advancing in their careers.
