Switzerland votes on June 14 on an initiative that would seek to stop the country's population hitting 10 million before 2050. Here is an overview of where things stand:
Current population: 9.1 million (November 2025)
Foreign nationals: 2.5 million (November 2025)
Eligible voters: 5.6 million
Who can vote: Swiss nationals aged 18 and over.
Since the introduction of the free movement of people in 2002, the Swiss population has grown by around 1.7 million, largely due to immigration. Switzerland has a direct democracy system. Citizens can challenge decisions taken by parliament in referendums, and propose new laws themselves in popular initiatives. A total of 100,000 valid signatures in 18 months are required to trigger a national popular initiative.
The initiative is entitled "No to a Switzerland with 10 million! (Sustainability Initiative)". Under its terms, if the permanent resident population exceeds 9.5 million before 2050, the government and parliament would have to take measures, notably on asylum and family reunification.
The government would also have to invoke or negotiate exemptions and safeguard clauses in international agreements deemed to contribute to population growth.
If the 10 million threshold is still exceeded before 2050, Switzerland would have to, within two years, terminate those agreements, including the one with the EU on the free movement of persons.
Surveys have shown the opposition camp gaining ground in a tight contest.

The vote is being proposed by the hard-right Swiss People's Party (SVP), the biggest in the country. "Uncontrolled immigration is causing Switzerland to grow far too quickly. The negative consequences are palpable in all areas of life," the Yes campaign says.
The seven-member government, comprised of ministers from the four biggest parties, including the SVP, is collectively against. It warns that adopting the measure would create uncertainty, threaten national stability, harm the economy, and threaten Swiss prosperity and internal security. Parliament, as a whole, also recommends rejecting the initiative, with both houses having clear majorities against.
All major parties except SVP are opposed. The Swiss Trade Union Federation, the Swiss Employers' Association and the business umbrella organisation economiesuisse are against the initiative. The proposal "will not create any additional housing or combat illegal immigration. It solves no problems, but creates new ones", the No campaign says. "It deprives our businesses and our entire society of a workforce we desperately need."
A double majority. To pass, the initiative must win both the national popular vote and the support of a majority of Switzerland's 23 full and six half-cantons.
