If both the base and upper section of a population pyramid are narrow but the middle is very broad, what can be inferred about total dependency?

Answer and explanation

Correct answer: It may be relatively low

A population pyramid with a narrow base has relatively few children, while a narrow upper section has relatively few elderly people. A very broad middle means that working-age adults form a large share of the population. Since total dependency mainly comes from children and older adults in relation to working-age people, both dependent groups are relatively small compared with the large middle group. Total dependency may therefore be relatively low, making option A correct.

This is an inference, not a precise calculation, because the exact age limits and percentages are not provided. The pyramid cannot prove that dependency is extremely high, and it will not consist only of elderly dependency because the base, although narrow, still represents children. Age structure is exactly the information used to make this estimate. Migration, fertility, and future ageing may later change the ratio, but the current shape suggests a comparatively low total dependency.
