How it works
The year for an age is your birth year plus that age: the calendar year in which you have that birthday. All values for that year come from the United Nations World Population Prospects 2024, medium variant, which runs to 2100.
Population and median age refer to 1 July of that year. The people born in your year and the share older than them refer to 1 January, when everyone born in your year still has the age before.
These are projections: one plausible future based on assumptions about births, deaths and migration. They are not forecasts, and the years after 2100 are outside them.
The page shows the world in a year when you would reach an age. It is not a forecast that you, or anyone, will reach it.
Frequently asked questions
How sure are these numbers?
Less sure the further ahead they go. The UN also publishes other variants with more or fewer births. The medium variant shown here is its central path.
Why does it stop at 2100?
The UN projections end in 2100. The tool never extends them on its own, so later years are shown as outside the available projections.
Why are some countries projected to shrink?
Where women have fewer than about two children on average for a long time, and migration does not make up the difference, each generation of parents is smaller than the last.
