If births are 900, deaths are 500, in-migration is 200 and out-migration is 300, what will be the actual population growth?

Answer and explanation

Correct answer: 300

The direct answer is A: 300 people. Actual growth includes both natural change and migration. Natural increase is births minus deaths: 900 − 500 = 400. Net migration is in-migration minus out-migration: 200 − 300 = −100, meaning 100 more people left than entered. Add the two components: actual growth = 400 + (−100) = 300. The same result comes from the complete formula: births − deaths + in-migration − out-migration = 900 − 500 + 200 − 300 = 300. Option A is correct. Option B ignores migration and gives only natural increase. Option C uses an incorrect combination of the figures. Option D incorrectly treats the movement figures as if they increased the population together. Memory cue: add births and arrivals; subtract deaths and departures.
