If children and elderly people each form 18 percent of a country's total population, what is the total dependent share?

Answer and explanation

Correct answer: 36 percent

In standard age-structure analysis, children and elderly people are counted as dependent groups because they are generally less likely to be in the working-age labour force. The question gives 18 percent for children and another 18 percent for elderly people. To find the combined dependent share, add the two percentages: \(18\%+18\%=36\%\). This is a percentage of the total population, not a ratio comparing dependents with workers.

Option C is therefore correct. The two dependent groups must both be included, so using only 18 percent would omit one group. The answer is not 28 percent because no subtraction or alternative weighting is required, and 64 percent would represent the remaining population only if calculated as \(100\%-36\%\), not the dependent share. The calculation assumes the stated groups do not overlap, as age groups normally do not.
