A country has a population of 40 million. If natural increase is 600000 and net migration is 200000, what is the total growth rate?

Answer and explanation

Correct answer: 2 percent

When natural increase and net migration are both given as numbers of people, add them to find the total population increase. Then compare that increase with the original population. The percentage rate is obtained by dividing the increase by the original population and multiplying by 100.

Total increase is \(600000+200000=800000\). The original population is 40,000,000, so the growth rate is \(800000\div40000000\times100=2\) percent. One percent would equal only 400,000 people in a population of 40 million. Therefore, the combined increase represents 2 percent, making option B correct.
