If the birth rate is slightly higher than the death rate but out-migration is very high, what may happen to the total population?

Answer and explanation

Correct answer: The total population may decline

Answer: B. A birth rate slightly above the death rate means natural increase is positive, but it may be small. Total change depends on both natural increase and net migration. If out-migration is very large, the negative migration balance can be greater than the small gain from births over deaths. The combined result can therefore be a decline in total population. A is wrong because rapid growth is not guaranteed when many people leave. C is wrong because births being higher than deaths means natural increase is positive, not zero. D is wrong because no automatic response in in-migration follows from the information. B correctly says “may decline,” because the exact result depends on the sizes of both components. Memory cue: a small natural gain can be outweighed by a large migration loss.
