If 300 people enter an area and 500 people leave, what will be the net migration?

Answer and explanation

Correct answer: Negative 200

Direct answer: D, negative 200. Net migration is found by subtracting the number leaving from the number entering: net migration = in-migration − out-migration. Here, 300 − 500 = −200. The minus sign is important because 200 more people left than entered. Option A is wrong because it gives the correct difference without the correct direction; the result is not positive. Option B is wrong because adding 300 and 500 gives the total movement, not net migration. Option C is wrong because the numbers entering and leaving are not equal. Option D is correct because the area lost a net total of 200 people through migration. Memory cue: subtract “out” from “in”; if out is larger, the answer is negative.
