If the elderly population is 18 percent and the working-age population is 62 percent, what is the approximate old-age dependency ratio?

Answer and explanation

Correct answer: 29.0

The old-age dependency ratio compares the elderly population with the working-age population. The standard calculation is \(\text{old-age dependency ratio}=\frac{\text{elderly population}}{\text{working-age population}}\times100\). Substituting the given percentages gives \(\frac{18}{62}\times100\approx29.03\). The result is expressed as about 29 elderly persons per 100 working-age persons.

Thus, option A, 29.0, is the correct approximate value. The 18.0 choice is only the elderly percentage and does not perform the comparison. The value 44.0 does not follow from the stated ratio, while 80.0 is also unrelated. The calculation assumes that the supplied age groups are the intended numerator and denominator.
