This dashboard has the latest statistics on the total population for constituencies in the UK, with a breakdown by age.

You can view figures for specific age groups or find data for a custom age range. The latest population estimates are for mid-2022. They are based on data from the 2021 census, combined with estimates of births, deaths, and migration. They should be treated as approximations rather than precise figures.
