Switzerland is heading to the polls in a referendum that could freeze the country’s population at 10 million. The initiative, backed by the right-wing Swiss People’s Party, would trigger immediate limits on immigration and halt citizenship for newcomers once the threshold is breached. But British demographers are warning that the plan is a recipe for economic stagnation.
“This is a demographic straightjacket,” says Professor James Treadwell of the London School of Economics. “Switzerland’s economy relies on a steady inflow of skilled workers. Capping that flow will lead to labour shortages, reduced tax revenues, and a strain on pension systems.” Treadwell’s analysis, based on Swiss Federal Statistical Office data, projects that GDP growth could fall by 0.5% annually within five years of the cap taking effect.
The referendum, scheduled for March 2025, has divided the Alpine nation. Proponents argue the cap safeguards Swiss identity and infrastructure. They point to overcrowded trains and soaring housing costs in Zurich and Geneva. But opponents, including the business lobby, warn of a brain drain. “Swiss companies already struggle to fill tech and healthcare roles,” says economist Dr. Helen Burkhardt of the University of Basel. “Closing the door now will hurt innovation.”
Documents obtained by this correspondent show that the Swiss Federal Council has privately modelled three scenarios. The worst case envisions a 2% contraction in the labour force by 2030. The cap would also end the bilateral agreements that allow EU citizens to work in Switzerland, a deal that has been a cornerstone of Swiss prosperity since 2002.
Meanwhile, the British demographers’ report, commissioned by a London-based think tank with ties to the City of London, has been circulated to Swiss diplomatic missions. It highlights parallels with Japan, where a restrictive immigration policy has contributed to decades of slow growth and a shrinking workforce. “Switzerland is sleepwalking into a Japan-style scenario,” says Treadwell. “Once you lose that demographic dynamism, it’s hell to get back.”
Critics of the report note that the think tank has financial interests in maintaining open borders. But the numbers are hard to dismiss. Switzerland’s population currently stands at 8.9 million, growing at about 1% per year. At that pace, the 10 million mark will be hit by 2030. The referendum would effectively slam the brakes on any growth beyond that.
Prime Minister Viola Amherd has not taken a public stance, but sources confirm her office is quietly urging a “no” vote. The Swiss People’s Party, however, is running an aggressive campaign linking immigration to crime and housing shortages. Their ads feature a train carriage packed with passengers, with the slogan: “Full. Stop.”
If the referendum passes, Switzerland would become the first country in the world to impose a hard population cap. The implications for neighbour France, Italy, and the broader Schengen area are significant. The EU has already signalled that a cap could violate the principle of free movement, potentially triggering diplomatic retaliation.
For now, the outcome is too close to call. But one thing is certain: the world will be watching on 9 March. And if the cap passes, British demographers won’t be the only ones sounding the alarm. They’ll just be the first to say ‘we told you so’.
