In Switzerland, a summer national referendum is planned concerning proposals put forth by the Swiss People's Party to cap the population at 10 million. Currently, the population stands at approximately 9.1 million, and the proposed measures would require the government to take action if the numbers reach 9.5 million, including halting immigration and potentially suspending agreements regarding the free movement of people with the European Union.

The Swiss People's Party argues that the rapid increase in population has placed significant strain on the country's infrastructure, asserting that about 27% of residents have foreign nationality. They believe that controlling population growth is essential to maintain the quality of life and resources available to citizens. The proposed cap is seen as a drastic measure aimed at managing the challenges that come with population expansion in a country that is already operating at near capacity in terms of its services and infrastructure.

Opposition to the proposals has emerged, notably from large corporations and employers who feel that immigration is vital for economic growth and sustainability in Switzerland. As the referendum approaches, the debate surrounding the implications of a population cap will intensify, making it a significant issue for both national policy and the future of Switzerland’s societal structure.
