Switzerland will hold a referendum this weekend on a proposal to cap the country’s permanent population at 10 million residents. The initiative, brought forward by the Swiss People’s Party, aims to control population growth through stricter immigration policies. Currently, Switzerland’s population is around 8.8 million. Proponents argue the cap is necessary to preserve Switzerland’s infrastructure, cultural identity, and natural resources. Opponents, including the government and most major political parties, contend the measure is impractical, would harm the economy, and could violate international agreements regarding the free movement of people. The vote is expected to be close and has reignited debate surrounding immigration within the country. The proposal has brought to the surface existing divisions regarding immigration policies in Switzerland.
