If ages 15 to 59 form 62 percent and total dependency ratio is 61.3, approximately what share of the population is dependent?

Answer and explanation

Correct answer: 38 percent

The dependency ratio is calculated as dependent population divided by working-age population, multiplied by 100. Here the working-age group is 62 percent and the ratio is 61.3. If the dependent share is \(D\), then \(\frac{D}{62}\times100=61.3\). Therefore, \(D=62\times0.613=38.006\), approximately 38 percent.

Option B is correct. The answer can also be checked by considering the population split: if 62 percent is working age, the remaining 38 percent must be outside that group and therefore dependent under the question’s classification. Options C and D confuse the ratio or working-age share with the dependent share. Rounding explains the approximate wording.
