What general change has occurred since 1940 in the percent of the American population age 25 and older that has completed a high school or higher level of education?

• A. It has increased.
• B. It has decreased.
• C. It has remained about the same.
• D. It fluctuated but with no clear trend.

Answer: (A)

The general change is that it has increased. Over the decades since 1940, a larger share of Americans aged 25 and older has completed high school or higher education. This rise comes from greater access to schooling and policy-supported expansion of both secondary and postsecondary opportunities. After World War II, programs like the GI Bill, the growth of community colleges, and broader high school enrollment opened paths to higher education for many Americans. As more people completed high school and pursued college or other postsecondary credentials, the overall proportion with at least a high school diploma or higher grew substantially. The other options don’t fit the long-term pattern, which shows a clear upward trend rather than a decrease, no change, or random fluctuation.
