The European Union is heading toward a profound demographic transformation over the coming decades, with its population projected to decline significantly while growing older.

Fresh projections from Eurostat indicate that the EU’s population will fall by 11.7% between 2025 and 2100 — a drop of around 53 million people.

In 2025, the EU’s population stands at approximately 451.8 million. After a brief slowdown during the COVID-19 pandemic, growth resumed in 2022 and is expected to continue modestly in the short term. The population is forecast to peak at about 453.3 million in 2029 before entering a long-term decline, reaching roughly 398.8 million by the end of the century.

These projections are based on assumptions about gradual convergence across EU countries in key demographic factors such as fertility rates, life expectancy, and migration patterns. However, the broader trend is clear: Europe is not only shrinking, but also ageing rapidly.

A continent growing older

One of the most striking aspects of the forecast is the shift in the EU’s age structure. Younger generations are expected to make up a smaller share of the population, while older age groups expand considerably.

 The proportion of children and young people (aged 0–19) is projected to fall from 20% in 2025 to 17% in 2100.

 The working-age population (20–64) is expected to shrink even more sharply, from 58% to just 50%.

At the same time, older Europeans will represent a growing share of society:

- People aged 65–79 will increase slightly, from 16% to 17%.

- Those aged 80 and over will see the most dramatic rise, jumping from 6% to 16% — a reflection of longer life expectancy across the continent.

The changing shape of Europe

Population pyramids illustrate this shift clearly. In 2025, the EU still resembles a relatively balanced society, though already marked by low birth rates and a large cohort of people over 50. By 2100, the structure changes dramatically: fewer young people, fewer workers, and a much larger elderly population.

This demographic shift has far-reaching implications. A smaller workforce could put pressure on economic growth, pension systems, and healthcare services, while increasing the dependency ratio — the number of retirees supported by working-age individuals.

Broader context: migration and regional differences

While the overall trend points downward, migration will play a crucial role in shaping Europe’s demographic future. In many EU countries, net migration has already become the main driver preventing faster population decline. Without it, the drop in population would be even steeper.

At the same time, demographic changes will not be uniform across the EU. Some countries — particularly in Eastern and Southern Europe — are expected to experience sharper population losses, while others may see more stability due to higher migration or relatively stronger birth rates.

A long-term challenge

Europe’s demographic trajectory highlights a key challenge for policymakers: how to adapt economies and social systems to a smaller, older population. From labor market reforms to family policies and migration strategies, governments will need to respond to ensure long-term sustainability.
