Overseas-born populations may have a quite different age profile to the general population, depending on when the main groups migrated. For instance in a student area they are likely to be younger, however an area which received a lot of post-war migration may have an older population.

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.
