If the birth rate is 13 per thousand, death rate is 22 per thousand, and net migration rate is +12 per thousand, what is the total growth rate?

Answer and explanation

Correct answer: +3 per thousand

Total population growth combines natural change and net migration. Natural change is found by subtracting the death rate from the birth rate. A negative result means deaths exceed births, while a positive migration rate can offset that loss. Thus, the calculation must include all three components rather than using the birth rate alone.

Natural change is \(13-22=-9\) per thousand. Adding net migration gives \(-9+12=+3\) per thousand. Therefore, the total population still increases by 3 persons per thousand, so option C is correct. Option B represents only natural change and ignores migration.
