If the birth rate is falling but the death rate is falling faster, what is the correct conclusion about population growth?

Answer and explanation

Correct answer: Population growth may still continue

The direct answer is A. Natural increase depends on the difference between the birth rate and the death rate, not on the birth rate alone. Suppose births fall from 20 to 15 per 1,000 people, while deaths fall from 10 to 5. The birth rate is lower than before, but the difference remains 10 per 1,000, so natural increase is still positive. Even if the difference becomes smaller, growth can continue as long as births exceed deaths. A is correct because it allows this positive gap to remain. B is wrong because falling rates do not make the existing population disappear. C is not supported: migration may contribute, but the information already allows natural increase to explain growth. D ignores demographic rates. Memory cue: compare birth rate minus death rate, not birth rate by itself.
