A region records 10400 births, 7100 deaths, 2600 in-migrants, and 3400 out-migrants. What is the total population change?

Answer and explanation

Correct answer: Increase of 2500

Population change has two parts: natural change and net migration. Natural change is found by subtracting deaths from births. Net migration is found by subtracting out-migrants from in-migrants. A positive final value means growth, while a negative value means decline.

Here, natural increase is \(10400-7100=3300\). Net migration is \(2600-3400=-800\), because 800 more people left than entered. Therefore, total change is \(3300+(-800)=2500\). The region therefore records an increase of 2500, so option A is correct. The value 3300 alone ignores migration.
