A country has a birth rate of 20 per thousand and a death rate of 6 per thousand, but its total growth rate is only 0.8 percent. What is the most likely explanation?

Answer and explanation

Correct answer: Negative net migration

Correct answer: B, negative net migration. Natural increase is calculated as the birth rate minus the death rate: 20 − 6 = 14 per thousand, which equals 1.4 percent. But the reported total growth is only 0.8 percent, which is 0.6 percentage points lower. Therefore, people leaving the country must be reducing the population growth; net migration is negative, approximately −0.6 percent or −6 per thousand. A is wrong because positive migration would add to 1.4 percent and make total growth higher. C contradicts the stated death rate and would make natural increase zero, not explain the given figures. D is wrong because births clearly contribute to natural increase. Memory cue: total growth = natural increase + net migration.
