If a country has a population of 72 million and a natural increase rate of -3.5 per thousand, what is the natural change in one year?

Answer and explanation

Correct answer: Decrease of 252000

A natural increase rate stated per thousand tells how many people are added or lost for every 1,000 members of the population. The rate here is negative, so it represents a natural decrease. To apply the rate, multiply the total population by the rate and divide by 1,000. The answer should retain the negative meaning as a decrease.

The calculation is \(72000000\times(-3.5)\div1000=-252000\). Thus, the population experiences a natural decrease of 252,000 people in one year. Therefore, option C is correct. The result concerns natural change only; migration would need separate information before calculating total population change.
