Swiss voters will head to the polls on Sunday, June 14, to decide whether to impose a constitutional cap on the country’s population in a closely watched referendum that could reshape immigration policy all around Europe.
The proposal, entitled “No to a Switzerland of 10 million!” was launched by the right-wing Swiss People’s Party (SVP), the largest party in parliament. It seeks to ensure that Switzerland’s permanent resident population remains below 10 million until 2050.
With the population currently standing at around 9.1 million—with foreigners making up over a quarter of the population—the initiative would oblige the government to take action once the number of residents exceeds 9.5 million.
Measures could include tighter rules on asylum, family reunification, and permanent residency permits. If these prove insufficient, Switzerland could ultimately be forced to renegotiate or even terminate its agreement with the EU on the free movement of people.
Supporters argue that rapid population growth has placed excessive pressure on housing, transport infrastructure, and public services. The SVP has linked immigration to soaring rents, congested roads and trains, rising crime, and a loss of national identity.
In a final appeal to voters ahead of the ballot, SVP president Marcel Dettling said: “We will not be intimidated. It is our democratic right to say: this cannot continue with immigration.” He urged Swiss citizens to “send a signal” by backing the initiative, arguing that the government had failed to act despite the approval of a separate anti-mass immigration referendum in 2014.
Business organisations and most major political parties have all urged voters to reject it, warning that it could damage the economy and isolate the country from its largest trading partner.
The business federation Economiesuisse has described the initiative as an “absurd proposal” that threatens Switzerland’s security and prosperity. Opponents argue that sectors including healthcare, construction, agriculture, tourism, and technology rely heavily on foreign workers.
Critics also point to Switzerland’s ageing population, saying immigration is essential to addressing labour shortages and sustaining the country’s social welfare system.
Opinion polls suggest the result could be extremely close. If approved, the measure would make Switzerland the first country to endorse a nationwide population cap through a public vote.
