If 50 people enter an area and 30 people leave, what will be the net migration?

Answer and explanation

Correct answer: 20

Direct answer: A, 20. Net migration measures the balance between people entering and people leaving an area. People entering are called in-migrants, while people leaving are called out-migrants. The formula is: net migration = in-migration − out-migration. Here, 50 people enter and 30 leave, so 50 − 30 = 20. Therefore, migration produces a net increase of 20 people in the area. A is correct because it uses the correct order and calculation. B, −20, would be correct only if 30 people entered and 50 left, so that leaving exceeded entering. C, 30, is merely the number of people who left; it does not show the balance. D, 80, incorrectly adds the two numbers, although net migration requires subtraction. Memory cue: in minus out.
