If in-migration and out-migration are equal, what will net migration be?

Answer and explanation

Correct answer: Zero

Answer: C, zero. Net migration is calculated by subtracting out-migration from in-migration: net migration = people entering − people leaving. If the two numbers are equal, the additions and losses balance exactly, so the net migration is zero. This does not necessarily mean that nobody moved; it means that the number entering equals the number leaving. Option A is wrong because a positive result requires more people to enter than to leave. Option B is wrong because a negative result requires more people to leave than to enter. Option D is wrong because equal flows do not double the population through net migration. Natural change from births and deaths may still change the total population, but net migration itself is zero. Memory cue: equal inflow and outflow cancel each other.
