Key numbers
United Kingdom among its neighbours
In plain language
Line up everyone in United Kingdom by age. The person in the middle is 40.0. That is the median: it says nothing about how old the oldest are or how many babies were born last year, only where the midpoint falls.
A median of 40.0 is older than the world's 30.6. For scale, the youngest country here, Central African Republic, has a median of 14.4 and the oldest, Japan, 49.4. Life expectancy at birth in United Kingdom is 81.3 years, so a person at the median age has, on a rough reckoning, about 41.3 years ahead of them.
The 2024figure is the UN's medium-variant number; its estimates end in 2023. For a year this close the projection barely differs from an estimate, since everyone counted has already been born.
