A country has a natural increase of 50000 and net in-migration of 20000. What is the total population change?

Answer and explanation

Correct answer: Increase of 70000

Total population change combines two components: natural increase and net migration. Natural increase is already given as 50,000, and net in-migration is positive 20,000, meaning more people entered the country than left it. Since both figures add to population, the total change is \(50{,}000 + 20{,}000 = 70{,}000\). The country therefore experiences an increase, not a decrease.

Option C is correct. Option A would incorrectly subtract the migration figure, option B would ignore migration, and option D would give the wrong direction as well as the wrong amount. A negative net migration would need to be subtracted, but the question specifically gives net in-migration of 20,000. Thus the total population rises by 70,000 people during the stated period.
