Between 1990 and 2020, the population of Switzerland increased from 6.6 million to 8.6 million. Of the total population, 25% are non-Swiss, with most of those being primarily from the EU. This is the second major anti-immigration initiative supported by the SVP in the last decade. The 2014 Swiss immigration initiative passed with a narrow majority of 50.33%; however protracted negotiations with the EU resulted in a 2016 compromise agreement that the SVP criticized as weak. The SVP has argued that the free movement hurts older Swiss workers, who would lose their jobs to young immigrants from the EU. Opponents have argued that, because of guillotine clauses in the bilateral agreements with the EU, this would terminate the Bilateral I agreements with the EU which include provisions on the reduction of trade barriers as well as barriers in agriculture, land transport and civil aviation. Germany is Switzerland's largest market with more cross-border trade amounting to more than Switzerland's trade with China and the United States combined. Most major parties in Switzerland oppose the initiative. The referendum failed to pass.
