If a country has a birth rate of 16 per thousand, a death rate of 21 per thousand, and net migration of +7 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 \(16-21=-5\) per thousand, so deaths exceed births by 5 per thousand. Net migration is positive at +7 per thousand, meaning arrivals exceed departures by 7 per thousand. Total growth combines natural change and net migration: \(-5+7=+2\) per thousand.

Therefore, option C is correct. The positive migration balance more than offsets the natural decrease, so the country's total population still grows by 2 persons per thousand population during the stated period. Option B represents only natural change, while option D represents only migration and leaves out the birth–death balance. All rates use the same per-thousand unit.
