What happens to population growth if death rate falls while birth rate remains the same?

Answer and explanation

Correct answer: Population growth increases

Answer: A, population growth increases, assuming other conditions such as migration do not offset the change. Natural increase is determined by births minus deaths. If the birth rate stays unchanged and the death rate falls, the difference between births and deaths becomes larger. More people survive, so the population grows more rapidly through natural increase. B reverses the relationship and is therefore wrong; a lower death rate does not always reduce growth. C is impossible because a fall in deaths does not remove the population. D is unrelated: migration can still occur whether the death rate rises or falls. For example, if births are 25 per 1,000 and deaths fall from 15 to 10 per 1,000, natural increase rises from 10 to 15 per 1,000. Memory cue: same births minus fewer deaths equals greater natural increase.
