The first SBC poll, conducted by the media group Tamedia in late April 2026, shows a notable divide among Swiss citizens regarding a proposal to limit the population to 10 million. This initiative, spearheaded by the right-wing Swiss People's Party (SVP), will be placed before voters on June 14.

As of now, Switzerland's population exceeds 9 million, with over 27% of residents being foreign nationals as of 2024. The proposal seeks to cap the population and necessitate steps to significantly reduce immigration, directly challenging Switzerland’s existing agreements that facilitate labor mobility within the EU.

The poll surveyed 16,176 respondents, revealing that while a slim majority supports the initiative, opposition still runs strong at 46%. This represents a shift in public sentiment compared to earlier polling data, which indicated 45% support and 47% against.

Concerns regarding rapid population growth and its impact on public infrastructure, housing, and healthcare are driving the momentum for this proposal. However, the Swiss government warns that the initiative could harm economic stability and international relations, particularly with the EU, which relies heavily on sustained collaboration.

Opponents, including various business and academic leaders, argue that limiting the population could lead to labor shortages in critical sectors and could adversely affect the economy, highlighting the tension between maintaining a stable population and ensuring economic growth.

With the referendum approaching, both proponents and opponents are mobilizing resources for their campaigns. This substantial public discourse on population management is set against ongoing debates about immigration, housing, and quality of life in Switzerland, revealing how demographic issues resonate deeply within Swiss society.
