Europe: future mothers can no longer be added — 19% fewer women aged 20–39 than in 1990
109.2 million then, 88 million in 2025. Everyone who will be 20–39 in 2045 has already been born: in the UN medium variant, migrants included, they will number 83.5 million, 24% fewer than in 1990. By 2100, 62.5 million.

Most children are born to women aged 20–39. How many there will be in 2045 is already known: all of them were born in 2006–2025. Even if births doubled tomorrow, it would not add mothers before 2045 — only migrants can, and the UN already counts them.
Women aged 20–39 in Europe. Solid line: UN estimates; dashed: the medium variant. Dots mark the 1990 peak and 2045, when everyone of that age is already born today.
- Europe (UN): women aged 20–39 million
1990: 109.2; 2025: 88; 2045: 83.5; 2100: 62.5
World Population Prospects 2024: women aged 20–24 … 35–39, summed over 50 European countries and territories, every five years. After 2023 the medium variant, which includes expected migration.
The 2045 figure hardly depends on births at all — only on deaths and moves. Beyond 2045 it depends on how many children are born and can miss either way.
A question for this picture
And how many babies are born in Europe now? Almost half as many as at the 1959 peak.
