When does population decrease due to migration?

Answer and explanation

Correct answer: When people go out of the area

Correct answer: B. When people leave an area for another place, the first area experiences out-migration. If more people leave than enter, its population can decrease because residents are being removed from its count. A is the opposite movement: people entering an area are in-migrants and generally add to the receiving population. C, an increase in births, normally adds people and supports population growth. D, an increase in services, is not itself a migration movement; it may influence people’s choices, but it does not directly mean that population decreases. The key is to identify the direction of movement from the viewpoint of the area being studied. Memory cue: out-migration goes out and can take population numbers down.
