A country has a birth rate of 9 per thousand, a death rate of 11 per thousand and a net migration rate of 4 per thousand. What is the total growth rate?

Answer and explanation

Correct answer: Positive 2 per thousand

Total population growth combines natural increase and net migration. Natural increase is calculated as births minus deaths. If deaths exceed births, natural increase is negative. Positive net migration can offset that loss, so it must be added with its sign rather than treated as a separate unrelated figure.

Natural increase is \(9-11=-2\) per thousand. Adding positive net migration gives \(-2+4=+2\) per thousand. Thus the population still grows overall, even though natural change alone would have reduced it. Option B, positive 2 per thousand, is correct. The result is not 4 because migration must be combined with the negative natural increase.
