Age Groups Back to Top

Across the UK as a whole, the median age is 40.7 years. In general, inner city areas show high concentrations of people aged 18-30, suburbs show larger numbers of small children and adults aged 30-50, and rural and small towns are more popular with older workers and retirees. Many poorer areas lack a majority age group, which is due in part to the people in that area being constrained by circumstance rather than being able to choose where to retire, raise a family or grow up.
