Switzerland votes Sunday on whether to cap its population at 10 million in a world-first referendum
On Sunday, Swiss citizens will decide whether to enshrine a 10 million permanent resident cap in law, a proposal driven by the right-wing Swiss People's Party that could force the country to exit its free movement pact with the EU.
The referendum proposal
Swiss voters head to the polls on 14 June to decide on the "No to 10 million!" initiative, drafted by the eurosceptic Swiss People's Party (SVP). If adopted, the government would be required to drastically tighten asylum and residence procedures once the population reaches 9.5 million. Upon hitting 10 million residents, Switzerland would have to withdraw from the bilateral agreement with the European Union on the free movement of persons, which has been in force for over 20 years.

Rapid population growth fueled by immigration
The debate has been stoked by a sharp increase in the number of residents. Between 2002 and 2025, Switzerland's population rose from 7.3 million to 9.1 million, a jump of 1.8 million. Nearly 80 percent of that growth is attributed to immigration. According to OECD data, the foreign-born share of the population reached 32 percent in 2024. Italians and Germans are among the largest groups of newcomers, and the weekly Der Spiegel notes that if Germany had grown at the same pace it would now have roughly 100 million inhabitants.

Supporters' warnings on housing and infrastructure
Proponents argue the influx is overloading housing, transport, schools and healthcare.
In cities, competition for flats is fierce.Ultimately, we are about protecting what we love and ensuring Switzerland remains a wonderful place to live.
A resident of Orbe, Herve Tissot, voiced concerns that acceptance has limits:In big cities, renting an apartment borders on a miracle.
Considering the size of our country, we have enough people here. Of course you can accept them, but what then? Are they to live on the streets, like in Paris?
Government opposition and economic risks
The Swiss government opposes the initiative, warning that capping the population would harm trade, the labour market and overall prosperity. Officials emphasise the country's humanitarian traditions and stress that ending free movement would weaken security cooperation with the EU. Critics also point out that the economy expanded by 24 percent over the same period of rapid population growth, and that by most metrics Switzerland does not appear overcrowded.
What a 'yes' could mean
Analysts note that a favourable vote would not trigger mass deportations. Instead, once the 9.5 million threshold is near, the government would be legally bound to restrict asylum and residency permits. The real rupture would be the mandated exit from the EU free movement agreement, a step some commentators compare to the Brexit vote in its potential disruption to Swiss-EU relations.
