If infant mortality rate falls, what effect can it have on population growth?

Answer and explanation

Correct answer: More children survive and growth may be affected

Correct answer: A. Infant mortality rate is the proportion or rate of infants who die during infancy. When it falls, more babies survive than before, so the number of surviving children can increase. This can influence population growth, especially when the birth rate remains high. The exact long-term effect also depends on future birth rates, general mortality, and migration; therefore the option correctly says growth “may be affected,” not that a particular increase is guaranteed. B is wrong because fewer infant deaths do not stop births. C is wrong because mortality remains an important population component even when infant mortality falls. D is wrong because infant survival does not necessarily make migration decrease. Memory cue: lower infant mortality means more infants survive; it does not mean fewer babies are born.
