If births and deaths are equal but people are leaving the area, what will the actual population change be?

Answer and explanation

Correct answer: Negative

Answer: B, negative. First calculate natural change: if births and deaths are equal, births minus deaths is zero. Next consider migration. People leaving the area are out-migrants, and out-migration reduces the number of residents. Thus, actual population change is zero natural change plus a negative migration effect, giving a decline in population. Option A is wrong because no positive inflow is stated. Option C is wrong because natural change is zero, but the total change is not zero after people leave. Option D is wrong because the information does not tell us that the change is rapid; it only tells us its direction. Option B is correct because departures make the final population smaller. Memory cue: equal births and deaths cancel each other, but out-migration still subtracts people.
