If natural increase is 300000 but net migration is negative 100000, what is the total population change?

Answer and explanation

Correct answer: Increase of 200000

Total population change combines natural increase with net migration. Natural increase adds 300,000 people, while negative net migration means that 100,000 more people leave than enter. The calculation is \(300000+(-100000)=200000\). Therefore, the population still rises, but the migration loss reduces the size of that rise.

Option A is correct: the total change is an increase of 200,000. Adding 100,000 instead would incorrectly treat negative migration as an inflow. A decrease would occur only if the negative migration were larger than the natural increase. “No change” would require the two quantities to cancel exactly, which they do not in this case.
