If a country's child share falls from 32 to 20 percent while the elderly share rises from 10 to 16 percent, what happens to the total dependent share?

Answer and explanation

Correct answer: From 42 to 36 percent

The governing concept is total dependent share, which here is obtained by adding the child share and the elderly share. Initially, dependents account for 32 + 10 = 42 percent. After the change, they account for 20 + 16 = 36 percent. Therefore the total dependent share falls by 6 percentage points, even though the elderly share rises. The 12-point reduction in child dependency is larger than the 6-point increase in elderly dependency. Option A is correct. Option B reverses the arithmetic, option C ignores the elderly group, and option D overlooks the unequal changes in the two dependent categories. A lower combined dependent share may create a potential demographic-dividend period.
