Switzerland will decide on Sunday (June 14, 2026) in a referendum on a proposal to cap the population at 10 million, a move some have likened to Britain’s Brexit vote that could have far-reaching consequences for the economy and relations with the European Union. What does the proposal envisage? That Switzerland’s population, currently at 9.1 million, must not exceed 10 ​million before 2050. That is not expected to occur until the early ⁠2040s. Once the population reached 9.5 million, the government would have to introduce stricter immigration rules, notably in asylum and family reunification. That is forecast to happen by about 2031, but could be as soon as 2029.

Once it hit the 10 million mark, Swiss authorities would be obliged to take “all available” measures to respect the limit, including potentially terminating international agreements that contribute to population growth. If the population was not brought under the limit within two years, and no special provisions were agreed in ⁠order to comply with it, Switzerland would have to end its 1999 freedom of movement agreement with the EU at the next possible date. That agreement allows EU citizens to live in Switzerland if they work or ​study there, with Swiss citizens having the same rights in the EU.

The right to stay, which also includes family members, can apply after employment has finished. Switzerland has an “emergency brake” on free movement in case of “serious economic or social problems”, subject to arbitration. Why has it been launched? Switzerland’s population has grown significantly faster than that of the EU since the freedom ​of movement accord with the bloc came into force in 2002. Many immigrants are drawn to the Alpine country by its higher wages and ⁠low taxes, which have helped bring in companies and created demand for skilled labour. The right-wing Swiss People’s Party, or SVP, launched the population cap initiative, arguing that public services and housing have come under pressure from mass immigration, and that crime has also risen.

What does it need to pass? For the proposal to be accepted, a majority of voters and of Switzerland’s cantons, or States, must back it. Swiss voters in 2014 narrowly backed an SVP initiative to reintroduce immigration quotas with the EU, though its impact was diluted in the ensuing political process.
