If infant mortality declines, what may be the initial effect on population change?

Answer and explanation

Correct answer: Population growth may rise as more children survive

Answer: A, population growth may rise because more children survive. Infant mortality is the death of infants during the early stage of life. When health care, nutrition, sanitation, or protection improve and infant deaths decline, a larger share of born children remains alive. In the initial period, this can increase the number of survivors and support population growth, especially if births remain at a similar level. A is carefully worded with “may,” because the final population trend also depends on births, deaths at other ages, and migration. B is false because lower infant mortality does not make the birth rate zero. C is false because migration continues to operate independently. D is the opposite of the likely initial effect. Memory cue: lower infant mortality means more newborns survive.
