If a country's total dependency ratio is 85 and elderly dependency ratio is 30, what is the child dependency ratio?

Answer and explanation

Correct answer: 55

The total dependency ratio combines two parts: child dependency and elderly dependency. It compares all dependents with the working-age population, usually per 100 working-age people. Thus, the total is obtained by adding the child and elderly ratios. To find the missing child part, subtract the known elderly part from the total.

Child dependency ratio = total dependency ratio − elderly dependency ratio = \(85-30=55\). Therefore, the correct choice is 55, option C. This means that for every 100 working-age people, there are about 55 child dependents after the ratios are expressed on the same base. The other values do not satisfy the required subtraction.
