Final answer:
Racial and ethnic diversity in the U.S. has increased over time, with the proportion of white Americans projected to decrease and the proportion of Hispanic Americans predicted to rise substantially. Workforce diversity has also increased as more women move up the promotion ladder within their organizations.
Step-by-step explanation:
Racial and ethnic diversity in the United States has increased over time. According to data from the U.S. Bureau of the Census, the proportion of white Americans in the population is projected to decrease from 78% in 2012 to 69% by 2060. On the other hand, the proportion of U.S. citizens who are of Hispanic background is predicted to rise substantially. Additionally, workforce diversity has increased as more women, who entered the workforce in the 1970s and 1980s, are now moving up the promotion ladders within their organizations.
