If a country's youth dependency ratio is 60 and old-age dependency ratio is 20, what is the total dependency ratio?

Answer and explanation

Correct answer: 80

Total dependency ratio has two components: youth dependency and old-age dependency. Both are calculated using the same working-age population as the denominator. Therefore, when the two component ratios are already given on that common basis, they can be added directly to obtain the total ratio.

Here, youth dependency is 60 and old-age dependency is 20. Thus, total dependency ratio = \(60+20=80\). This means that there are 80 dependents per 100 working-age persons, counting children and older people together. Therefore, option C is correct. The figures should not be averaged or multiplied; adding them is appropriate because the two groups are separate components of total dependency.
