What does positive net migration mean?

Answer and explanation

Correct answer: More people enter than leave

Direct answer: Option C is correct. Net migration is calculated by comparing the number of people entering an area with the number leaving it. In simple form, net migration equals in-migration minus out-migration. If more people enter than leave, the result is positive. For example, if 800 people move into a town and 500 move out, net migration is +300. This positive value can add to the town’s population, although the final population also depends on births and deaths. Option A describes negative net migration because departures are greater than arrivals. Option B gives zero net migration: movement may occur, but the numbers balance. Option D is too extreme and is not required for net migration to be positive or zero. A useful memory cue is “in minus out”: a larger in-flow gives a positive result.
