In which condition is the population of an area most likely to decrease?

Answer and explanation

Correct answer: Deaths are high and out-migration is high

Direct answer: B, when deaths are high and out-migration is high. A population decreases when people are removed faster than they are added. High deaths reduce the number of living residents, while out-migration means residents leave the area for another place. In option B, both processes reduce the population, so decline is most likely. A would increase population because births add people and in-migration brings people in. C would also generally increase population because many births add people while few deaths remove them. D describes in-migration, which adds residents rather than taking them away. The word “out” can help: out-migration means people go out of the area. Memory cue: deaths and out-migration are population-reducing processes.
