A country has a population of 36 million and a natural increase rate of 16 per thousand. With zero migration, what is the natural increase in one year?

Answer and explanation

Correct answer: 576000

The correct answer is C: 576,000 people. A natural increase rate of 16 per thousand means that, in one year, 16 people are added naturally for every 1,000 people in the population. Convert the rate into a fraction: 16/1000. Then multiply by the population: 36,000,000 × 16/1000 = 576,000. With zero migration, there is no additional increase or decrease from people moving in or out, so the calculated natural increase represents the total population increase under the stated conditions. Option A uses a rate of 10 per thousand and is too low. Option B does not result from multiplying 36 million by 16/1000. Option C is correct. Option D is too high and would correspond to a rate of 20 per thousand. The key distinction is that “per thousand” is not “percent”: divide by 1,000, not by 100.
