If births are 1200, deaths are 800, in-migration is 500 and out-migration is 300, what is the actual change?

Answer and explanation

Correct answer: 600

The correct answer is B: the actual population change is 600 people. Use the complete balance equation: actual change = births − deaths + in-migration − out-migration. Substitute the values step by step: births minus deaths is 1200 − 800 = 400, which is the natural increase. The migration balance is 500 − 300 = 200. Add the two balances: 400 + 200 = 600. Therefore the population increases by 600, assuming all figures refer to the same area and time period. A is only the natural increase and ignores migration. C adds or handles one component incorrectly and is not the result of the complete equation. D also does not follow the signs of the four quantities. Remember that births and in-migration add people, while deaths and out-migration subtract people. Memory cue: add the two gains and subtract the two losses, or use the balance formula without changing signs.
