What is the effect of out-migration on population change?
Answer and explanation
Correct answer: It decreases the population of that area
In out-migration, people leave an area to live elsewhere. Therefore, the total population of the area they leave decreases. Birth rate and death rate are separate components of population change; out-migration does not eliminate death rate or necessarily increase birth rate. Exam tip: people leaving an area means population decreases there, while people arriving means population increases.
