If an area has 1500 births, 1000 deaths, and net migration of negative 300, what is total growth?

Answer and explanation

Correct answer: 200

The direct answer is A: 200. Use the population-growth relationship step by step. First calculate natural increase: births minus deaths equals 1,500 − 1,000 = 500. Next include net migration. A negative net migration of 300 means that 300 more people left than entered, so it reduces the change by 300. Therefore total growth = natural increase + net migration = 500 + (−300) = 200. A is correct. B is only the natural increase and ignores the negative migration. C incorrectly adds 300 instead of subtracting it, as if migration were positive. D adds births and ignores deaths and migration, so it is not a population-growth calculation. The final value is positive, meaning the population still increased, but only by 200 people. Memory cue: calculate births minus deaths first, then apply the migration sign carefully.
