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

Answer and explanation

Correct answer: More children will survive and growth may be affected

Direct answer: A. Infant mortality rate is the proportion or number of infants who die during infancy, according to the stated measure. When this rate falls, more born children survive. That increases the surviving population and can affect population growth, although the final effect also depends on fertility, deaths at other ages, and migration. Option A is correctly worded as a possible effect. B is wrong because fewer infant deaths do not stop births. C is wrong because survival and migration are different demographic processes. D is wrong because mortality changes do not reduce the physical area of a region. Memory cue: lower infant mortality means more infants survive, not fewer births automatically.
