If births are 1500, deaths are 900, in-migration is 400 and out-migration is 700, what is the actual growth?

Answer and explanation

Correct answer: 300

Direct answer: A, 300. Actual growth combines natural increase and net migration. First calculate natural increase: births − deaths = 1,500 − 900 = 600. Next calculate net migration: in-migration − out-migration = 400 − 700 = −300. The negative sign means 300 more people left than entered. Therefore, actual growth = 600 + (−300) = 300. The same result comes from the complete formula: actual growth = births − deaths + in-migration − out-migration = 1,500 − 900 + 400 − 700 = 300. B is only the natural increase and ignores migration. C adds figures incorrectly and does not subtract deaths and out-migration properly. D is not a growth calculation at all; it treats several flows as if all increased the population. Memory cue: births and arrivals add; deaths and departures subtract.
