If an area has 2000 births, 1300 deaths, 500 in-migrants, and 900 out-migrants, what will be the total growth?

Answer and explanation

Correct answer: 300

Correct answer: A, 300. Use two parts. First calculate natural increase: births − deaths = 2000 − 1300 = 700. Next calculate net migration: in-migrants − out-migrants = 500 − 900 = −400, meaning there is a net loss of 400 people through migration. Add the two components: total growth = natural increase + net migration = 700 + (−400) = 300. A is correct. B is wrong because it does not correctly combine natural increase and net migration. C is only the natural increase, so it ignores the net loss from migration. D is the number of deaths and is not a growth calculation. Formula: total population change = (births − deaths) + (in-migration − out-migration).
