In which condition will actual growth be less than natural increase?

Answer and explanation

Correct answer: Out-migration is high

Direct answer: B, when out-migration is high. Natural increase means births minus deaths. Actual population growth also includes people entering and leaving: actual growth = births − deaths + in-migration − out-migration. If many people leave an area, the out-migration term is subtracted, so actual growth becomes smaller than natural increase. For example, if births exceed deaths by 100 people but 30 people leave, actual growth is only 70. A is wrong because in-migration adds people and makes actual growth larger. B is correct because out-migration removes people from the population. C describes natural increase with no outward movement, so actual growth equals natural increase. D gives zero natural increase but positive in-migration, so actual growth is positive and greater than natural increase. Memory cue: people entering add; people leaving subtract.
