If births are 1,800, deaths are 2,200 and net migration is 700, what will be the total population change?

Answer and explanation

Correct answer: An increase of 300

The direct answer is A: an increase of 300. First calculate natural change by subtracting deaths from births: 1,800 − 2,200 = −400, so the population loses 400 people through natural change. Next include net migration, which adds 700 people: −400 + 700 = +300. Therefore, the final population increases by 300. B gives only the natural decrease and ignores migration. C counts migration but ignores the loss caused by more deaths than births. D incorrectly adds all figures without treating deaths as a subtraction. The useful formula is: total change = births − deaths + net migration. Memory cue: births and arrivals add; deaths and departures reduce the total.
