If the birth rate is 14 per thousand, death rate is 20 per thousand, and net migration rate is +8 per thousand, what is the total growth rate?

Answer and explanation

Correct answer: +2 per thousand

Natural change is found by subtracting the death rate from the birth rate. Here it is \(14-20=-6\) per thousand, meaning there is a natural decrease of 6 per thousand. Net migration is positive at +8 per thousand, so it must be added to the natural change. Total growth is \(-6+8=+2\) per thousand. Therefore option C is correct.

The negative natural change alone would reduce the population, but the inflow of migrants is larger than that reduction. The excess of 2 people per thousand produces positive total growth. Rates must be kept in the same unit, per thousand, before adding them. The answer is not +8 because migration is only one component, and it is not −6 because natural change alone is not total growth.
