In a country, 24 percent of the population is aged 0-14, 66 percent is aged 15-64, and 10 percent is aged 65 and above. What is the approximate total dependency ratio per 100 working-age persons?

Answer and explanation

Correct answer: About 52

The total dependency ratio compares all dependent-age people with the working-age population. Children aged 0–14 and older people aged 65 and above are counted as dependents, while ages 15–64 form the working-age group. The ratio is expressed per 100 working-age persons, not simply as the percentage of dependents in the whole population.

The dependent share is 24% + 10% = 34%, and the working-age share is 66%. Therefore, the ratio is \(34/66\times100\approx51.5\), which rounds to about 52. Thus, option B is correct. A value of 34 would be only the dependent percentage, not the dependency ratio, because the required denominator is the working-age population.
