Overview
- The nationwide referendum set for June 14 asks voters whether to block Switzerland from reaching 10 million people before 2050 by forcing measures if the population passes 9.5 million and requiring termination of certain international agreements if 10 million is exceeded.
- Polls show a tight race with recent surveys clustering around 47% supporting the initiative and about 52% opposing it, making the outcome uncertain ahead of the vote.
- The proposal is driven by the right‑wing Swiss People's Party (SVP), which says rising population and immigration strain transport, housing and public services.
- The federal government, parliament, major parties, unions and business groups warn a 'yes' would cut access to skilled workers, jeopardise ties to the EU and could shrink growth by an estimated 7.1% between 2028 and 2045, a loss economists have put at roughly 685 billion Swiss francs.
- Campaigners say the measure would hit sectors that rely heavily on foreign staff such as healthcare, hotels, research and manufacturing, and the initiative must win both a national majority and a majority of cantons to pass.
