Germany’s population has fallen for the first time in five years, dipping by 110,000 to 83.5 million in 2025, according to official figures released this week. The decline, though modest at 0.1 per cent, marks a sharp reversal from the steady growth seen since 2011, interrupted only by the pandemic year of 2020. Statisticians in Wiesbaden point to a widening gap between births and deaths: the natural deficit swelled to 352,000, while net immigration halved to 235,000, no longer sufficient to offset the country’s demographic drag. Viewed from Berlin, the numbers underscore a structural shift that is quietly reshaping Europe’s largest economy.

Across the Alps, the demographic debate has taken a very different turn. Switzerland, where the population has already surpassed 9.1 million, held a referendum on capping the total at 10 million by 2050. The proposal, driven by the right-wing Swiss People’s Party, would have triggered severe restrictions on family reunification, residence permits, and immigration once a threshold of 9.5 million was reached. Voters rejected the initiative decisively, but the campaign left a bitter residue. Swiss Greens have now launched a parliamentary offensive, arguing that the debate was marred by disinformation, fake social media accounts, and artificial intelligence, and warning that without new safeguards, future votes on bilateral accords or federal elections could be similarly poisoned.

The Swiss vote unfolded against a backdrop of mounting infrastructure strain. Rail networks across the country are notoriously overburdened, particularly on the east-west axis of the Swiss Plateau, where hundreds of thousands of commuters endure chronically overcrowded trains. While capacity expansion projects are underway, analysts in Geneva and Zurich note they remain insufficient to meet demand. The same pressures are felt in Germany, where Munich’s rail hub — described internally by Deutsche Bahn as “too old, too broken, too full” — faces a funding squeeze that could force cuts to regional and suburban services, even as the Bavarian capital’s population continues to swell. The dilemma is acute: austerity threatens to degrade connectivity precisely when demographic growth demands more capacity.

Italy, meanwhile, confronts its own demographic reckoning. Ahead of a major conference in Rome on 18 June, policymakers, businesses, and experts are grappling with a relentless decline in birth rates and rising longevity that strain pension systems, labour markets, and welfare services. The Italian case mirrors broader southern European trends, where the imbalance between generations is accelerating. Across the continent, the picture is fragmented: Germany’s population is now shrinking, Switzerland’s is still growing but stirring political anxiety, and Italy’s is ageing faster than its institutions can adapt.

Infrastructure emerges as a common fault line. In Switzerland, the rejected population cap has revived calls for pre-financing rail expansion to relieve bottlenecks. In Germany, the Munich rail hub’s predicament illustrates a wider national challenge: maintaining and modernising networks in the face of competing fiscal demands. The Swiss Greens’ push for new rules on political campaigning — targeting disinformation, fake accounts, and artificial intelligence — reflects a broader European concern that demographic pressures are being exploited to polarise voters rather than to forge pragmatic solutions. As populations diverge and infrastructure ages, the continent’s ability to manage these transitions with both investment and integrity will define its resilience in the decades ahead.
