If there are 3200 births, 2300 deaths and net migration is negative 1100, what will the total change be?

Answer and explanation

Correct answer: A decrease of 200

Direct answer: Option A is correct. First calculate natural increase: births minus deaths equals 3,200 − 2,300 = 900. This means the population would increase by 900 through births and deaths alone. Next include net migration. A negative net migration of 1,100 means 1,100 more people left than entered, so it contributes −1,100. Total population change equals natural increase plus net migration: 900 + (−1,100) = −200. The negative sign means a decrease of 200 people. Option B reverses the sign and is incorrect. Option C gives only the natural increase and ignores migration. Option D incorrectly adds all figures, even though deaths and negative migration reduce population. Memory cue: total change = births − deaths + net migration; keep the sign of negative migration.
