Final answer:
The share of U.S adults over the age of twenty-four who are college graduates is about 30 percent, specifically 36% as reported by the BLS in 2019.
Step-by-step explanation:
About what share of U.S adults over the age of twenty-four are college graduates? The correct answer is 30 percent, which corresponds to option b. According to the Bureau of Labor Statistics (BLS), in 2019, it was reported that approximately 36% of the U.S population aged 25 and over had a bachelor's or higher degree. While this percentage has grown from 33.6% as noted in 2014 statistics, it still represents less than half of the adult population. Thus, even though going to college can provide greater opportunities to consume goods and services, not everyone chooses or is able to pursue higher education due to various factors that impact such decisions.
