A cohort with unusually high births twenty years ago is most likely to appear in today's age pyramid in what form?

Answer and explanation

Correct answer: A bulge around age 20

An age pyramid shows the number or proportion of people in different age groups. A cohort is a group born during the same period. As that group grows older, it moves upward through the age structure rather than remaining at the base. Its unusually large size therefore appears as a wider section at the age the members have reached.

A large birth cohort from about twenty years ago is now concentrated near age 20, allowing for deaths and migration. It will appear as a bulge around that age, so option A is correct. It will not remain only at the base, because the base represents the youngest children. Nor will it create an equal increase in every age group; the concentration follows that cohort’s movement through time.
