If a country has a population of 40 million and a natural increase rate of -3 per thousand, what is the approximate natural change in one year?

Answer and explanation

Correct answer: Decrease of 120000

A natural increase rate of -3 per thousand means that natural change is a loss of 3 people for every 1000 people. The negative sign is important: it indicates that deaths exceed births, excluding migration. To find the number, multiply the population by \(-3\div1000\).

For 40 million people, the change is \(40000000\times(-3\div1000)=-120000\). Thus, the population experiences an approximate natural decrease of 120000 people in one year. Option C is correct. The result is not a total population change because migration has not been included.
