If 50 people enter an area and 30 people leave what will be the net migration?
Answer and explanation
Correct answer: 20
Net migration is calculated by subtracting the number of people leaving an area from the number entering it: \(50-30=20\). Therefore, the net migration is 20, meaning migration increases the area’s population by 20 people. \(-20\) would apply if 20 more people left than entered. Exam tip: remember, net migration = in-migration − out-migration.
