If a country has a population of 60 million and a natural increase rate of -2.5 per thousand, what is the approximate natural change in one year?

Answer and explanation

Correct answer: Decrease of 150000

A natural increase rate of -2.5 per thousand means that the population experiences a natural loss of 2.5 people for every 1,000 people during one year. The population is 60 million, or 60,000,000. Convert the rate to a fraction and multiply: \(60,000,000\times\frac{-2.5}{1000}=-150,000\). The negative sign represents a decline.

Therefore, the approximate natural change is a decrease of 150,000 people, so option B is correct. This calculation includes only births and deaths; migration is not included in natural change. A decrease of 100,000 or 250,000 results from using the wrong rate or base. The supplied explanation correctly interprets the negative value and reaches the correct option.
