If a population pyramid has a narrow base and a very broad 35 to 49 age group, which change is likely over the next twenty years?

Answer and explanation

Correct answer: A rise in the elderly population and potentially in elderly dependency

A population pyramid shows the population’s age and sex distribution. A narrow base indicates relatively small younger cohorts, while the broad 35 to 49 group represents a large cohort. Over the next twenty years, many members of that cohort will move into older age groups. This makes an increase in the elderly population likely; elderly dependency may also rise, depending on the size of the working-age population. Option B is the best answer. The pyramid does not support a guaranteed rise in fertility or a doubling of the working-age population.
