If a country has a birth rate of 12 per thousand, a death rate of 9 per thousand and net migration of 5 per thousand, what is the total growth rate?

Answer and explanation

Correct answer: 8 per thousand

Population growth from natural causes is found by subtracting the death rate from the birth rate. Net migration must then be added, because positive net migration means more people enter the country than leave it. All the given rates use the same unit, per thousand, so they can be combined directly without another conversion.

Natural increase is \(12-9=3\) per thousand. Adding net migration gives \(3+5=8\) per thousand. The total growth rate is therefore 8 per thousand, which represents the combined effect of births, deaths, immigration, and emigration. Option C is correct. Choosing 3 would ignore the positive contribution of migration.
