If total dependents form 42 percent of a country's population and children form 26 percent, what is the elderly share?

Answer and explanation

Correct answer: 16 percent

Total dependent population is made up of the child group and the elderly group. Therefore, if the total dependent percentage and the child percentage are known, the elderly percentage is found by subtracting the child share from the total dependent share. Both values must be percentages of the same total population.

The total dependent share is 42 percent, and children account for 26 percent. Hence the elderly share is \(42-26=16\) percent. The result can be checked by adding the two dependent groups: \(26+16=42\) percent. Therefore, option C is correct. The working-age share is not needed for this calculation, although it would be 58 percent as the remainder.
