If in-migration and out-migration are equal in a region, what will be the net effect of migration?

Answer and explanation

Correct answer: The net effect of migration will be zero

Correct answer: B, the net effect of migration will be zero. Migration changes population when people enter or leave a region. In-migration means people arrive, while out-migration means people leave. Net migration is calculated as in-migration minus out-migration. For example, if 500 people enter and 500 people leave, the calculation is 500 − 500 = 0. Therefore, migration alone causes no increase or decrease in the region's population, although the people and families involved have certainly moved. A is wrong because the number entering is exactly balanced by the number leaving. C is wrong for the same reason: there are not more departures than arrivals. D is unrelated because migration does not make births stop. Remember: equal inflow and outflow means zero net migration.
