The age structure of the population with a need for assistance is an important indicator of whether the disabilities highlighted are age related or otherwise. Generally need for assistance increases with age, so a comparison with the age structure of the same population in a benchmark area may reveal an older or younger population with significant need for assistance.

Five year age groups present a classic age profile of the population. Each age group covers exactly five years, which enables direct comparison between each group.
