The population of European Union countries is projected to decline by 53 million (11.7%) between 2025 and 2100, according to a forecast by the EU’s statistical office (Eurostat).
In 2025, the EU population was estimated at 451.8 million, resuming its growth trend in 2022 after a hiatus caused by the COVID-19 pandemic in 2021. The population is projected to grow over the next three years, peaking at 453.3 million in 2029, after which it will gradually decline to 398.8 million by 2100.
By the start of the next century, the share of children and youth (ages 0–19) in the total population will decline to 17% from 20% last year, and the working-age population (ages 20–64) will fall to 50% from 58%. In contrast, the share of people aged 65–79 will rise to 17% from 16%, and those aged 80 and older to 16% from 6%, according to a Eurostat report.
