The Great European Shift: Mapping the Continent’s Population Trends Toward 2100
Europe is standing on the precipice of a profound demographic transformation. Latest analysis from Eurostat reveals a continent in flux, where the traditional maps of population density and national size are expected to be redrawn by the end of the century.
Whereas some nations are poised for growth, the overarching trend is a significant decline. The European Union’s population is projected to drop by approximately 53 million people—a decline of nearly 12 percent—by 2100 compared to 2025 levels.
Winners and Losers: Which Countries Will Grow?
This proves not a uniform decline across the board. A select group of countries is expected to buck the trend. Norway, Sweden, Switzerland, and Iceland are projected to observe their numbers rise, alongside nine EU member states.
Among EU nations, Ireland and Sweden are expected to experience the most significant growth, with increases ranging between 10 and 20 per cent. However, this growth comes with a caveat: in Sweden, deaths are expected to outnumber births starting next year, meaning growth will be driven almost entirely by migration.
Spain presents another engaging case. While its population is projected to grow from 49 million to almost 50 million, this growth is fragile. Net migration currently outweighs the combined impact of births and deaths, but this migration surge is expected to decline steeply by the early 2030s.
The Steepest Declines
On the opposite end of the spectrum, 18 EU countries are projected to see their populations shrink. The most dramatic drops—exceeding 30 per cent—are expected in Poland, Lithuania, and Latvia.
Other nations will see more “modest” changes. France, for instance, is projected to dip slightly from 69 million in 2025 to 67 million by 2100. Austria is also expected to see relatively minor fluctuations.
A New Hierarchy of Power: The Largest Nations
The demographic shift will inevitably alter the political and economic weight of EU member states. Germany is slated to remain the most populous EU country, though it will still face a decline from 84 million to 75 million residents.
The most significant shift occurs with Italy. Currently the third-largest EU country by population, Italy is projected to fall to fourth place by 2100, with its population plummeting from 59 million to 45 million.

The “Demographic Winter”: Ageing and Migration
The driving force behind these numbers is what experts call “continuous negative natural change.” Simply put, people are dying faster than they are being born.
The scale of this gap is staggering. Between 2025 and 2100, Eurostat projects 253 million births against 410 million deaths—a net loss of 157 million people. Net migration is expected to add 104 million people, but this is only a partial compensation for the natural decline.
This imbalance leads to a “progressive ageing of the population.” The share of the population aged 80 and over is expected to jump from 6 per cent to 16 per cent. Meanwhile, the proportion of children and working-age adults will continue to shrink.
Where will the youngest populations be?
By the end of the century, the “youngest” populations are projected to be found in:
- Bulgaria
- The Netherlands
- Germany
Conversely, the most ageing societies will likely be Lithuania, Malta, Cyprus, Italy, Spain, Portugal, and Poland.
Frequently Asked Questions
Why is the EU population projected to decline?
The primary cause is a negative natural change, where the number of deaths significantly exceeds the number of births, leading to an overall ageing population.
Which EU countries are expected to grow the most?
Ireland and Sweden are projected to see the largest growth among EU member states, with increases between 10 and 20 per cent.
Will migration stop the population decline?
Migration is the only factor contributing to growth in certain countries, but on a continental scale, the projected 104 million migrants will only partially offset the net reduction of 157 million people caused by natural change.
Which country will be the most populous in the EU by 2100?
Germany is expected to remain the largest EU country, despite its own projected population decline to 75 million.
