According to the latest population projections from Eurostat, the EU population is expected to decline by 11.7% between 2025 and 2100. This translates to a predicted decrease of 53.0 million people in the EU by the start of the next century.
In 2025, the EU population was estimated at 451.8 million, having resumed its growth trend in 2022, after the COVID-19 pandemic disruption in 2021. Looking ahead, the population is projected to continue to increase over the next 3 years, peaking at 453.3 million in 2029, before gradually declining to 398.8 million by 2100.
