If the birth rate is falling but the death rate is falling faster, what may happen to the growth rate?

Answer and explanation

Correct answer: The growth rate may increase

The direct answer is A: the growth rate may increase. Natural increase depends mainly on the difference between the birth rate and the death rate. If both rates fall but the death rate falls faster, the gap between births and deaths can become wider. For example, if the birth rate falls from 30 to 24 while the death rate falls from 20 to 10, the gap changes from 10 to 14, so natural growth rises. Migration can also affect total population growth, so the word “may” is important rather than “must.” Option B is wrong because falling death rates do not make the population automatically zero. Option C is wrong because area alone does not determine growth. Option D is wrong because migration continues to influence total change. Memory cue: compare the gap between birth and death rates, not one rate alone.
