If a country's working-age population is 65 percent and child dependency ratio is 40, what percentage of total population is children?

Answer and explanation

Correct answer: 26 percent

The child dependency ratio measures children in relation to the working-age population. A ratio of 40 means that for every 100 working-age people, there are 40 children. The working-age group is 65 percent of the total population, so the child share is obtained by multiplying 65 by 0.40.

Therefore, child share = \(65\times0.40=26\) percent of the total population. This gives option B. The value 40 should not be selected directly, because it is the dependency ratio, not the children’s percentage of the whole population. The remaining population may include elderly people, but that does not affect this calculation.
