Switzerland is holding a referendum on a proposal to cap its population at 10 million residents. Currently, the country has approximately 9.1 million inhabitants. The vote is unprecedented globally and could significantly restrict immigration, including from the European Union, with which Switzerland has a free movement agreement. Public opinion is divided on the issue, and polls suggest a close result. Supporters argue the cap is necessary to protect resources and quality of life, while opponents warn of economic consequences and potential damage to international relations. The outcome will likely have a substantial impact on Switzerland’s future demographic and immigration policies. The referendum reflects growing concerns about population density and its effects on the nation’s infrastructure and social services.
