Switzerland is holding a national referendum on Sunday to decide whether to implement a cap on its total population. The proposal, initiated by the right-wing nationalist Swiss People’s Party (SVP), aims to limit immigration levels. If passed, the measure would introduce a maximum number of residents allowed in the country, a move proponents say is necessary to manage growth and resources. Opponents argue the cap is impractical, economically damaging, and violates international agreements regarding freedom of movement. The vote reflects growing concerns about immigration within Switzerland and its potential impact on national identity and infrastructure. The outcome will significantly shape Switzerland’s future immigration policies and demographic trajectory. The proposed cap is estimated to affect up to 10 million residents.
