In plain language

Line up everyone in Kiribati by age. The person in the middle is 22.8. 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 22.8 is younger 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 Kiribati is 66.5 years, so a person at the median age has, on a rough reckoning, about 43.7 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.
