Explanation:

The median age of a population is related to life expectancy. As life expectancy increases, more people live longer, which can raise the median age. The chart shows an increase in the median age of the U.S. population over time. Options A (population increasing) is not directly indicated by median age data. Options B (poverty level decreasing) and C (average income decreasing) are not related to median age.

Answer:

D. Life expectancy is increasing.
