A province has a natural increase of 40000 but net out-migration of 65000. What is the total population change?

Answer and explanation

Correct answer: Decrease of 25000

Total population change includes both natural change and migration. Natural increase adds people because births exceed deaths. Net out-migration subtracts people because more residents leave than newcomers enter. To find the total, the signed effects must be combined rather than added as positive numbers. A negative result means that the population decreases overall.

Here the natural increase is +40,000 and net out-migration is −65,000. Therefore total change is \(40000-65000=-25000\). The province loses 25,000 people overall, even though births exceed deaths by 40,000. Hence option A, a decrease of 25,000, is correct. Adding the two magnitudes would incorrectly give 105,000 and ignore the direction of migration.
