If a country has a large elderly population but also very high in-migration of young adults, which change may appear in the population pyramid?

Answer and explanation

Correct answer: Both the upper and middle sections may be relatively broad

A population pyramid displays age composition by showing the relative size of different age groups. A large elderly population increases the width of the upper part, whereas the arrival of many young adults enlarges working-age groups, commonly visible in the middle. Consequently, both the upper and middle sections may become relatively broad at the same time. The base would be widened mainly by high fertility or many young children, not by adult migration. The middle cannot logically disappear when young adults are entering, and the entire pyramid would not necessarily narrow. Therefore, option A is correct.
