Switzerland votes on initiative to cap population at 10 million, testing EU relationship

The initiative

On Sunday, Swiss voters will decide whether to enshrine a strict population ceiling in the constitution. The "No 10-Million-Switzerland!" initiative, launched by the right-wing Swiss People's Party (SVP), would cap the country's permanent resident population at 10 million. Currently, 9.1 million people live in Switzerland, 2.4 million of them foreign nationals. If adopted, the constitution would require the government to restrict asylum and family reunification once the population reaches 9.5 million, which could happen in the 2030s. Should that prove insufficient, Switzerland would be mandated to terminate its bilateral agreement with the EU on free movement of persons.

Political campaign

SVP figurehead Christoph Blocher summed up the sentiment:

Too many are coming, and the wrong ones! And that has to stop.

Unlike past SVP campaigns that stoked fears of foreign cultures, this year's messaging focuses on quality-of-life complaints: housing shortages, rising rents, crowded trains, and strained infrastructure. The party blames these solely on immigration, resonating with what political scientist Claude Longchamp calls

a nostalgic middle-class audience

dreaming of a Switzerland untouched by modern European integration. Yet SVP stands alone: the government, all other parliamentary parties, business groups, and trade unions oppose the cap.

Economic and diplomatic risks

The business community warns that restricting immigration would choke off access to skilled workers. Multinational corporations like Nestlé and Novartis rely on foreign talent. The government's official information portal cautions that the initiative would cause legal uncertainty, damage the economy, threaten prosperity and internal security, and undermine the bilateral path with the EU. Participation in the Schengen and Dublin agreements could be at stake, unraveling close cooperation on security and asylum.

Foreign population composition

Foreign nationals account for 27 percent of permanent residents. The largest groups come from Italy (15 percent of the foreign population), Germany (14 percent), Portugal (11 percent), and France (8 percent). The remaining 52 percent includes people from many other countries.

Polls and voting

Polls initially pointed toward acceptance of the initiative, but sentiment shifted about two weeks ago, and the outcome now appears too close to call. Past Swiss referendums have often deviated from final poll numbers, adding uncertainty. Vote counting begins at midday. If approved, Switzerland would become the first country with a rigid population cap in its constitution.
