If the death rate falls rapidly while the birth rate remains high for several years, how will the gap between births and deaths change?

Answer and explanation

Correct answer: The gap will widen and natural increase will accelerate

Natural increase is determined by the gap between the birth rate and the death rate. If the death rate falls rapidly while the birth rate stays high, fewer people are being lost and many people continue to be added. Consequently, the difference between births and deaths becomes larger, so natural increase accelerates. Therefore, option A is correct.

For example, if the birth rate remains 30 per thousand and the death rate falls from 20 to 10 per thousand, the gap increases from 10 to 20 per thousand. The birth rate has not risen, but the lower death rate still makes the net natural increase greater. The gap does not have to become zero; it widens as long as births remain substantially above deaths. Thus, option A best describes the change.
