If the birth rate is low but outsiders are coming for jobs, why can the total population increase?

Answer and explanation

Correct answer: In-migration adds people to the population

The direct answer is A: in-migration adds people to the population. Population change depends on three major components: births, deaths, and migration. A low birth rate means that fewer newborns are being added than before; it does not mean that no people can enter the area. When workers come from another place for employment, they are migrants entering the receiving area. Their arrival can be greater than the reduction caused by low births, so the total population may rise. A is correct because it identifies the effect of in-migration. B is wrong because a low birth rate does not remove people already living there and cannot make the population automatically zero. C is wrong because employment is a common reason for people to migrate. D is wrong because a death rate does not automatically increase merely because outsiders arrive. Memory cue: population change = births − deaths + in-migration − out-migration.
