Which option correctly gives the processes that reduce population?

Answer and explanation

Correct answer: Deaths and out-migration

Answer: B, deaths and out-migration. Deaths reduce the number of people living in a region. Out-migration also reduces that region’s population because residents leave for another place. Thus both processes in B have a subtracting effect. A is incorrect because births and in-migration add people to the receiving population. C is not correct because births add people, and the word migration by itself does not specify whether people are entering or leaving; only out-migration is clearly reducing for the origin region. D is incorrect because in-migration adds people, while health is not a population-reducing process in this classification. Memory cue: deaths and departures take people away from the population count.
