If a country's elderly share is rising and child share is declining while the working-age share remains nearly constant, what is the most appropriate conclusion about total dependency?

Answer and explanation

Correct answer: Total dependency may remain roughly stable while its composition changes

Total dependency compares the dependent population with the working-age population. The dependent group commonly includes children and older people, so a simple measure is \(\text{total dependency} = \frac{\text{children + elderly}}{\text{working-age population}} \times 100\). If the working-age share stays nearly constant, a fall in child share may be offset by a rise in elderly share.

Therefore option A is the best conclusion: total dependency may remain roughly stable while its composition changes from more youth dependency to more old-age dependency. It is not certain to become zero, and both child and elderly dependency do not have to rise together. The age structure is clearly changing, so option D is also incorrect.
