In a country, 30 percent of people are aged 0-14, 60 percent are aged 15-59, and 10 percent are aged 60 and above. What is the total dependency ratio?

Answer and explanation

Correct answer: 66.7

The dependency ratio compares people usually outside the working-age group with those in the working-age group. Here, children are 30 percent and older people are 10 percent, so total dependent population is \(30+10=40\) percent. The working-age group is 60 percent. Therefore, \((40/60)\times100=66.7\).

This means there are about 66.7 dependants for every 100 people in the stated working-age group. Option A is correct. The calculation must use the combined dependent share as the numerator and the working-age share as the denominator; using only children or dividing by the total population would give a different, inappropriate measure.
