Switzerland holds referendum on population cap at 10 million

Swiss voters headed to the polls on Sunday to decide whether the country should impose a population cap of 10 million people by 2050, in a closely watched referendum that has sparked intense debate over immigration, economic growth and Switzerland’s future relationship with the European Union.

The proposal, backed by the right-wing Swiss People's Party, is being promoted as a “sustainability initiative” aimed at easing pressure on housing, public services, transportation and the environment. Critics, however, view it as the latest attempt to curb immigration in the Alpine nation, reports BBC.

Switzerland’s population has risen from about 7.3 million in 2002 to roughly 9.1 million today, with around 27 percent of residents born abroad. Under the proposal, authorities would be required to take action once the population reaches 9.5 million, ensuring it does not exceed 10 million before 2050.

Potential measures could include limiting asylum approvals, restricting family reunification rights for foreign workers and, if necessary, terminating international agreements such as the EU’s free movement of people.

The Swiss government, most political parties, trade unions and business groups oppose the initiative, arguing it could worsen labor shortages and damage relations with the European Union, Switzerland’s largest trading partner.

Opponents have labeled the proposal a “chaos initiative,” warning that sectors such as healthcare, hospitality and elderly care rely heavily on foreign workers. They also fear the measure could isolate Switzerland at a time of growing global economic and geopolitical uncertainty.

Recent opinion polls suggest a tight race. Surveys indicate that about 52 percent of voters oppose the proposal, while 45 percent support it, leaving a significant number of undecided voters likely to determine the outcome.

Supporters argue that rapid population growth has contributed to housing shortages, overcrowded public transport, rising healthcare costs and strained public services.

“We have lost control,” said Nils Fiechter, a young lawmaker from the Swiss People’s Party, arguing that immigration has placed excessive pressure on infrastructure and social services.

Opponents reject that view, saying structural policy failures rather than immigration are behind many of the country’s challenges.

“It is not migrants who determine rent levels or health insurance premiums,” said Helin Genis, a Social Democratic politician from Bern, arguing that blaming immigration risks deepening social divisions rather than solving problems.

Business leaders have also raised concerns that the population cap could undermine Switzerland’s economy. Employers warn that the country’s aging population increasingly depends on foreign workers, particularly in hospitals, care homes and hotels.

Economiesuisse, Switzerland’s leading business association, has cautioned that approving the proposal could complicate ties with Brussels and jeopardize access to the European labor market.

The referendum comes as Switzerland faces broader economic and geopolitical challenges, including rising defense spending, higher energy costs linked to global conflicts, and concerns about international trade relations.

Final results are expected later Sunday.
