If natural increase is +15 per thousand and total growth is +5 per thousand, what is the net migration rate?

Answer and explanation

Correct answer: -10 per thousand

Population change can be separated into natural increase and net migration. Natural increase is the difference between births and deaths, while net migration is the difference between immigrants and emigrants. Their rates combine to produce the total growth rate, so the relationship is \(\text{total growth} = \text{natural increase} + \text{net migration}\). Rearranging gives \(\text{net migration} = \text{total growth} - \text{natural increase}\).

Substituting the given values gives \(5-15=-10\) per thousand. The negative sign means that more people left than entered, by 10 people per thousand of population during the relevant period. This outflow partly offset the positive natural increase of 15 per thousand and left total growth at 5 per thousand. Therefore, option B, \(-10\) per thousand, is correct.
