If children form 30 percent and the working-age population 50 percent of a country, what is the child dependency ratio?

Answer and explanation

Correct answer: 60

The child dependency ratio compares the population of children with the working-age population, not with the total population. The standard calculation is: child dependency ratio = (child population ÷ working-age population) × 100. Substituting the given values gives (30 ÷ 50) × 100 = 60. Thus, there are 60 children for every 100 working-age people. Option A is only the child share of the total population, and option B is the working-age share. Option D does not follow from the stated figures. Therefore, option C is correct. The ratio helps planners estimate likely pressure on schools, child health, nutrition, and household support.
