A city's total population grows by 20 percent, but the number of children grows by only 5 percent. What is the most appropriate conclusion?

Answer and explanation

Correct answer: Growth likely came more from other age groups or migration

The total population and the age composition do not have to change at the same rate. In this case, total population rises by 20 percent, but the number of children rises by only 5 percent. This means the larger increase must mainly be found among adults, older people, or migrants who are not children. The data do not identify one exact cause, but they support a cautious comparison of age groups.

Therefore, option A is the most appropriate conclusion. A higher total population does not prove that the birth rate doubled, because births are only one influence and the time period and age definitions matter. The number of children did not decline; it increased by 5 percent. Nor is the total figure necessarily wrong. The conclusion should remain probabilistic rather than absolute.
