In a country, ages 0 to 14 form 31 percent, ages 15 to 59 form 57 percent, and ages 60 and above form 12 percent. If over the next decade the child share falls to 24 percent and the elderly share rises to 18 percent, what happens to the working-age share?

Answer and explanation

Correct answer: From 57 to 58 percent

The governing concept is the mutually exclusive age distribution of a population: children, working-age people and elderly people together make 100 percent. In the new situation, children and elderly people account for 24 + 18 = 42 percent. The remaining working-age share must therefore be 100 − 42 = 58 percent. It rises from the original 57 percent to 58 percent, an increase of one percentage point, so option A is correct. The child share falls by seven points, while the elderly share rises by six points; the net reduction in dependent groups is one point. The other options do not satisfy the 100-percent total.
