In a region, 20 percent of the population is aged 0-14, 65 percent is aged 15-59, and 15 percent is aged 60 and above. What is the total dependency ratio per 100 working-age people?

Answer and explanation

Correct answer: About 54

The governing concept is the dependency ratio, calculated as the dependent population divided by the working-age population, multiplied by 100. Children aged 0–14 and older people aged 60 and above are counted as dependents here, so the dependent share is 20 + 15 = 35 percent. The working-age share is 65 percent. Therefore, total dependency ratio = (35 ÷ 65) × 100 = 53.846..., approximately 54 dependents per 100 working-age people. Option A is correct. Option B confuses the dependent percentage of the total population with the ratio per 100 workers. Options C and D do not follow from the given formula or percentages.
