If the birth rate is 18 per thousand, death rate is 24 per thousand, and net migration is +9 per thousand, what is the total growth rate?

Answer and explanation

Correct answer: +3 per thousand

Total growth rate is obtained by combining natural change with net migration. Natural change equals the birth rate minus the death rate. Here it is \(18-24=-6\) per thousand, meaning a natural decrease of six people per thousand.

Net migration is positive nine per thousand, so it is added to the natural change: \(-6+9=+3\) per thousand. Therefore option C is correct. Although deaths exceed births, enough people enter through migration to produce a small overall increase. The answer is not +9 because that would ignore natural change.
