Natural change in population is related to what?

Answer and explanation

Correct answer: Births and deaths

Direct answer: Option A, births and deaths. Natural population change is calculated from vital events that occur through births and deaths. Natural increase is births minus deaths; if births are greater, the population has natural increase, and if deaths are greater, it has natural decrease. Migration is not included in this narrow definition, although it is included when we discuss total population change. Option B is wrong because migration concerns people moving between places, while area is a physical measurement. Options C and D are wrong because rainfall, wind, minerals and soil may influence settlement or living conditions, but they are not the direct components used to calculate natural change. A learner should not confuse “natural change” with “all population change.” Total change includes natural change plus migration. Memory cue: natural change asks what happens through life events—births and deaths; migration asks who enters or leaves.
