A country records 2000 births, 1500 deaths, 700 in-migrants, and 900 out-migrants. What is the total population change?

Answer and explanation

Correct answer: Increase of 300

Total population change has two parts: natural change and net migration. Natural change is births minus deaths. Net migration is in-migrants minus out-migrants. The final answer must combine both results, because a country can have natural growth while losing people through migration. Positive values indicate an increase and negative values indicate a decrease.

Natural increase is \(2000-1500=500\). Net migration is \(700-900=-200\), because 200 more people leave than enter. The total is \(500+(-200)=300\), so the population increases by 300. Therefore option A is correct. Choosing 500 would count only births and deaths and would ignore the larger number of out-migrants.
