If children form 18 percent and elderly people 26 percent of a country's population, which population pyramid is more likely?

Answer and explanation

Correct answer: Narrow base and relatively broad upper part

A population pyramid represents the relative size of age groups from the youngest at the base to the oldest near the top. Here, children account for only 18 percent, so the base should be relatively narrow. Older persons account for 26 percent, a larger share than children, so the upper part should be comparatively broad, indicating an ageing population and generally low fertility with substantial survival to old age. A very broad base would imply a large child population and higher fertility, which conflicts with the data. Equal widths are also unsupported. Thus option B best matches the described age structure.
