If births are 700, deaths are 400, in-migration is 200 and out-migration is 100, what will be the actual growth?

Answer and explanation

Correct answer: 400

Correct answer: B, 400. Actual growth includes natural increase and net migration. First calculate natural increase: births − deaths = 700 − 400 = 300. Next calculate net migration: in-migration − out-migration = 200 − 100 = 100. Add these two effects: 300 + 100 = 400. In one expression, actual growth = 700 − 400 + 200 − 100 = 400. Option A ignores migration and gives only natural increase. Option C and option D do not follow from the required additions and subtractions. The safe rule is to add births and arrivals, then subtract deaths and departures.
