Swiss voters head to the polls on June 14 to decide on a proposal to cap the country's permanent resident population at 10 million — and for the first time, a majority now backs it. A poll of 16,176 respondents published on April 24 shows 52% in favor, 46% against and 2% undecided.

The survey, conducted by media group Tamedia, newspaper 20 Minuten and polling institute Leewas on April 22 and 23, and published in the Tages-Anzeiger, marks a shift from early March, when 45% supported the initiative and 47% opposed it. The Tages-Anzeiger noted that Swiss referendum proposals typically lose support as voting day approaches.

The initiative comes from the right-wing Swiss People's Party (SVP), the largest party in Switzerland's government. More than 114,000 signatures brought it to a national vote. The Federal Council, Switzerland's governing body, rejected the proposal in March 2025, and in December both chambers of the Swiss Parliament formally recommended a "no" vote.

What does the cap actually change?

The proposal would limit the permanent resident population to 10 million before 2050. If the population crosses 9.5 million before then, the government must act:

• Take measures to curb immigration, including tightening rules for asylum and permanent residence
• Renegotiate international agreements that drive population growth, in the proposal's own wording

If the population reaches 10 million, Switzerland would likely have to abandon its free-movement agreement with the EU, in place for more than two decades. That agreement lets citizens of EU member states and Switzerland live, work and buy property in each other's countries.

Switzerland passed 9 million residents last year. The population has grown by 1.9 million since 2000, according to think tank Avenir Suisse, largely driven by immigration. Foreign nationals now account for about 27% of residents. Net migration runs at roughly 80,000 people per year, the Swiss Federal Statistical Office reports, while natural growth was only around 6,000 in 2024. The fertility rate stands at about 1.3 children per woman, well below the replacement rate of 2.1.

Who would be affected?

EU nationals form the largest group affected, since scrapping free movement would end their automatic right to live and work in Switzerland. Asylum seekers would also face tighter rules once the 9.5 million threshold is crossed.

Critics question how much the asylum lever can achieve. Of roughly 30,000 asylum applications last year, only 7,300 received a refugee permit, and another 5,000 received a temporary permit because returning them would violate the non-refoulement principle protected by international law.

Switzerland already sets annual quotas for non-EU immigration: 8,500 permits for non-EU citizens and 3,500 for U.K. citizens in 2024. Those quotas are consistently underfilled — recent years saw about two-thirds of the non-EU quota and a fifth of the U.K. quota used.

Why do supporters want the cap?

The SVP argues that "uncontrolled immigration" places overwhelming pressure on public infrastructure and pushes up housing costs. If enacted, the fixed ceiling may become the first of its kind enshrined in law, although other countries have tried to limit population growth before: China's one-child policy ran from 1979 to 2015, and Singapore ran a "Stop at Two" campaign in the 1970s.

The Swiss proposal functions more like an immigration quota than a birth-control policy — but with a horizon fixed at 2050, unlike the regularly reviewed quotas used by the U.S., Canada, Japan and several European countries.

What do opponents say?

Many lawmakers warn the cap could hurt an economy already hit by U.S. tariffs that struck Swiss luxury goods, watches, machinery and pharmaceuticals. "To permanently restrict immigration," the Federal Council said last March, "Switzerland would have to take measures that would be detrimental to its prosperity and incompatible with Switzerland's international obligations."

Economiesuisse, Switzerland's largest business federation, warns that limiting immigration would create labor shortages in healthcare, research and services that depend on foreign workers — shortages that an aging population and falling birth rate will only deepen.

"A policy that exacerbates the labor shortage and at the same time jeopardizes relations with the E.U. endangers the quality of life and prosperity of all people living in Switzerland," Rudolf Minsch, Economiesuisse's chief economist, said in a statement.

Mindy Marks, an economist at Northeastern University, pointed to the benefits free movement brings companies with international branches and standardized licensing. "People are an asset. People innovate. We figure stuff out, we produce new things. We make the pie bigger," she told Northeastern Global News in March.

What happens next?

The vote takes place on June 14. If a majority approves, the constitutional amendment takes effect and Switzerland's immigration policy — and its relationship with the EU — enters uncharted territory. Voters can verify details of the initiative and referendum through official Swiss government channels.
