Geneva — Swiss voters rejected a proposal on Sunday that sought to limit the country’s population to 10 million by 2050, according to early results. Preliminary tallies showed that approximately 55% of participants opposed the measure, with voter turnout nearing 59%. Results were still being finalized from multiple cantons.

The initiative was promoted by the Swiss People’s Party (SVP), the nation’s largest right-wing political faction, which has consistently campaigned on curbing immigration. The party argued that rapid population growth has strained Switzerland’s infrastructure, housing market, social services, natural resources, and overall quality of life. Switzerland’s population has increased by nearly 25% over the past generation, and nearly one-third of residents are foreign-born.

Opponents, including the federal government, parliament, and major business groups such as EconomieSuisse, contended that the influx of foreign workers benefits key sectors like healthcare, finance, pharmaceuticals, and technology. They warned that the proposal risked undermining Switzerland’s bilateral agreements with the European Union, which, while Switzerland is not an EU member, facilitate economic cooperation, cultural exchange, and the free movement of people.

The initiative, dubbed the “sustainability initiative,” would have compelled the government to introduce restrictive measures if the population reached 9.5 million before 2050. These measures could have included curtailing asylum claims, limiting family reunification, and restricting residency permits. Implementation also might have endangered Switzerland’s agreement with the EU on free movement, potentially disrupting access to European labor markets.

Public opinion varied across the country. In Geneva, a cosmopolitan city hosting numerous United Nations offices and humanitarian organizations, about two-thirds of voters opposed the measure. Supporters of the initiative, like Maria Lalu, a former diplomatic worker from the Philippines who has lived in Switzerland since the 1980s, expressed a desire for more “orderly” immigration. Conversely, opponents such as schoolteacher Natascha Robert highlighted the country’s multiculturalism as a strength and cautioned that the measure could damage relations with the EU.

Switzerland regularly employs referendums to allow citizens direct participation in policymaking, typically holding votes on various issues four times annually. Migration has remained a contentious subject in the country for decades, with past referendums reflecting deep divides. The only immigration-related referendum to pass in recent memory was the narrow approval of a 2014 initiative targeting mass immigration.

Demographically, Switzerland differs from many other European states, as most migrants originate from European countries rather than from developing regions. Since Switzerland and the EU liberalized cross-border movement in 2002, the Swiss population grew to 9.1 million by the end of 2025, with corresponding increases in economic output. The Organization for Economic Cooperation and Development reported in 2024 that 32% of Swiss residents were foreign-born, a figure surpassed only by Luxembourg and Australia among its member nations.

Experts note that while many countries impose immigration limits, Switzerland would have been the first to vote to cap its total population, reflecting the unique aspects of its direct democracy and demographic challenges.
