If births and deaths are equal in an area but in-migration is high, what will total population growth be like?

Answer and explanation

Correct answer: Positive

Correct answer: A, positive. Natural increase is calculated as births minus deaths. Since births and deaths are equal, natural increase is zero. However, total or actual growth also includes migration. In-migration means people enter the area, so it adds to the population. Therefore, zero natural increase plus a large number of incoming people produces positive total growth. Option A is correct because the population increases through in-migration. Option B is wrong because people are entering rather than leaving. Option C is wrong because natural growth is zero, but total growth is not zero when in-migration occurs. Option D is wrong because the change can be measured if the numbers of births, deaths and migrants are known. Memory cue: births − deaths gives natural change; add in-migration and subtract out-migration for actual change.
