If a country's working-age population is 55 percent, child population is 35 percent, and elderly population is 10 percent, what percentage of the population is dependent?

Answer and explanation

Correct answer: 45 percent

In an age-structure calculation, dependent population is commonly treated as the sum of children and older people, while the working-age group is treated as the main economically active group. Here, children make up 35 percent and elderly people make up 10 percent of the total population. Adding these two dependent groups gives \(35+10=45\) percent.

The working-age share of 55 percent is not added to the dependent share, because the question asks only for the child and elderly groups. The three percentages together also check the calculation: \(55+35+10=100\) percent. Therefore, 45 percent of the population is dependent under this simplified age-based classification. Option B is correct. In a detailed demographic study, exact age limits may vary, but that does not affect this calculation.
