If people aged 0 to 14 form 35 percent of a country's total population, what type of age structure may this indicate?

Correct answer: Youthful age structure

When people aged 0–14 make up 35 percent of the total population, children form a large share of the population. Such a high child proportion usually indicates a youthful age structure. It often reflects a history of relatively high fertility, although the exact interpretation can also be influenced by mortality, migration, and the chosen age categories. A youthful structure creates strong demand for schools, immunization, nutrition, child health, and eventually jobs as these children grow older.

Option A is correct. Option B would be associated with a larger proportion of older people and a smaller child share. Option C is impossible as a description of the whole population because children are clearly present in substantial numbers. Option D is also incorrect: children are dependents, so the population cannot have zero dependency merely because the working-age group exists. The 35 percent figure therefore most reasonably signals a youthful population.
