What can be the general effect of a falling death rate on population growth if the birth rate remains unchanged?

Answer and explanation

Correct answer: Natural increase may rise

Natural increase is the difference between the number of births and the number of deaths in a population. If the birth rate remains unchanged but the death rate falls, fewer people are removed from the population through death. The gap between births and deaths can therefore become larger, causing natural increase to rise. This is a general demographic relationship, not an absolute prediction for every unusual situation.

Thus option A is correct: natural increase may rise. For instance, if births stay at 100 while deaths fall from 20 to 10, the difference rises from 80 to 90. A falling death rate does not automatically stop migration, make growth zero, or cause immediate population decline. The word “may” appropriately allows for other demographic circumstances.
