743 million people, and already past its peak
Europe is home to about 742.2 million people, stretching from Portugal’s Atlantic coast to the Ural Mountains that mark the continent’s traditional eastern edge1. That figure counts, by the UN’s own convention, the Russian Federation’s population in full and the United Kingdom regardless of its EU exit; a narrower “Europe without Russia” reading would put the total closer to 600 million, and “the EU” alone is smaller still, at 450 million1.
The continent’s population peaked around 2020 at just under 750 million and has been easing downward every year since. The UN’s medium-variant projection has it falling further, to about 703 million by 20501. Among the world’s major regions, Europe is the one already past the top of its curve.

The birth rate fell well before the migration story did
Fertility across Europe sits at 1.41 children per woman, far short of the 2.1 needed to hold a population steady, and the UN doesn’t expect much recovery: even by 2050, the projected rate is still only 1.51. The population keeps aging in step. Median age was 43.1 in 2026 and is projected to reach 46.2 by 2050, while the share of Europeans living in cities climbs from 76.2% toward 85.2% over the same stretch1.
Zoom into the EU specifically, a narrower 450 million-person slice of the wider continent, and a sharper pattern shows up. Deaths have outnumbered births in the EU every single year since 2012, yet the EU’s population still grew for a fourth consecutive year in 2024, reaching 450.4 million. The only reason: positive net migration ran ahead of that natural decline by roughly a million people2.
That cushion isn’t evenly spread. In 13 EU countries, Germany among them, migration was the sole reason population grew at all in 2024, natural change having already turned negative. In 8 others, including Poland, Italy, and Romania, even migration wasn’t enough, and population fell anyway2. Migration is buying time for parts of the EU without reversing the underlying trend anywhere in it.
No single country carries this continent
Russia is Europe’s most populous country under the UN’s convention, at roughly 143 million people, which is only about one in five Europeans1. That’s a strikingly small share for a “biggest” country to hold. Brazil accounts for close to half of South America’s population, and the United States for well over half of North America’s; Europe has never organized itself around one demographic giant the same way, a legacy of centuries as a patchwork of sovereign states rather than a population imbalance.
Germany, the EU’s own largest member, comes next at around 84 million, followed by the United Kingdom (70 million), France (67 million), Italy (59 million), and Spain (48 million)1. Stack the top six together and they still don’t reach two-thirds of the continent’s total. Whatever happens to Europe’s population over the coming decades will be decided across dozens of national capitals at once.
The mountains that keep four rivers running
The Alps are a comparatively narrow band of high ground, yet they carry an outsized share of the water that Europe’s biggest rivers depend on. The Rhine draws 34% of its total discharge from the 15% of its catchment that lies in the Alps, a 2.3-times disproportion; the Rhone draws 41% from 23% of its catchment, the Po 53% from 35%, and the Danube 26% from just 10%8. The gap widens further in summer, when lowland rainfall is scarcest and Alpine snowmelt matters most: the Rhine’s Alpine share at its mouth climbs from 34% across the year to 52% in June alone8.
That water tower is running down. Swiss Alpine glaciers lost almost 3% of their remaining ice volume in the 2024/2025 season alone, the fourth-largest annual loss on record, and roughly a quarter of their total volume since 20159. Over a thousand smaller Swiss glaciers have vanished already. Glacier melt, not rain or seasonal snow, is what keeps these rivers running during dry summers, so that decline lands hardest in exactly the season these rivers can least spare it: one modelling study of the Rhine projects summer flows could fall 5-25% further downstream and 30-70% upstream in future drought years, as there’s simply less ice left to buffer the shortfall10.
A continent that imports almost everything it burns
The EU met 57% of its energy needs through net imports in 2024, more than half its total supply, with oil making up 67% of what it brought in and natural gas another 24%3. That dependency isn’t limited to fuel. In 2025, China alone supplied 40% of the EU’s rare earth element imports, the materials behind everything from wind turbines to electric motors, and was the dominant single supplier of several other critical raw materials besides4. Both figures describe the EU specifically, the 450 million-person institutional core of the wider continent, but they capture something true of Europe more broadly: a place that manufactures and consumes at a scale its own ground doesn’t supply, running largely on what arrives from somewhere else.
What 743 million people cost the planet
If everyone in the world lived like the average European, humanity would need 2.82 Earths to keep up, well above the 1.70 the world as a whole currently uses11. Put another way: at that rate, the planet’s entire annual biocapacity budget would be spent by around May 9, four months into the year.
Carbon is by far the largest piece of that footprint, at about 55%11. That tracks with the import story above: carbon in this accounting is specifically the CO2 from burning fossil fuels for transport, heating, and industry, not from clearing land, and a continent that nets in 57% of its energy from abroad is, by definition, burning a great deal of imported oil and gas at home3. Cropland is the next-largest share, at 21%, a genuinely different story: one of the most intensively farmed landscapes on Earth, not a land-clearing one11. You can track the fossil-fuel side of that story on its own terms via global CO2 emissions.
If everyone in the world lived like the average person in Europe, we'd need 2.82 Earths to keep up.
1 Earth (world biocapacity per person)
What's driving it
That's more than the world average of 1.7 Earths. Europe also draws on more biocapacity than its own land can renew.
Europe’s own land can’t keep up with what its population uses: its biocapacity per person (3.18 global hectares) is smaller than its footprint (4.17), making the continent a net ecological debtor domestically, drawing on resources and capacity beyond its own borders11. That’s the same shape as the energy and raw-materials dependence above, just measured in land instead of barrels.
There’s a genuine improving trend behind that carbon number, though. The EU’s net greenhouse gas emissions sat an estimated 37% below 1990 levels in 2024, with a legally binding target of at least 55% below by 20305. Most of the recent progress is coming from the power sector: solar overtook coal in EU electricity generation for the first time in 2024, gas-fired generation fell for a fifth consecutive year, and wind and solar combined pushed renewables to nearly half of all EU electricity6.
Already running one of the world’s biggest clean-power experiments
Set against that carbon driver, this is a real, measurable head start most of the world hasn’t caught up to. Renewables supplied about 34% of the world’s electricity in 20257; the EU alone was already close to half from wind and solar in 20246.
Europe’s share of that global number is already running well ahead of it.
Europe’s 742.2 million people are part of a world of more than 8 billion, one of the few major regions where that number is heading down rather than up.
