In which condition will actual change and natural change be equal?

Answer and explanation

Correct answer: When net migration is zero

Direct answer: A. Natural change is the difference between births and deaths. Actual or total population change includes natural change plus net migration. Net migration is in-migration minus out-migration. Therefore, if the number entering equals the number leaving, net migration is zero, and actual change is equal to natural change. For example, births may exceed deaths, producing natural increase; if arrivals and departures balance each other, migration adds nothing to the final change. A is correct because it removes the migration component from the population-change equation. B is wrong because high in-migration makes actual change larger than natural change unless it is balanced by out-migration. C is wrong for the same reason in the opposite direction: high out-migration reduces actual change. D is not the required condition; if there are no births and deaths, natural change is zero, but equality depends on net migration also being zero. Memory cue: actual change = natural change + net migration.
