When immigrants in Switzerland apply for citizenship, the decision is made in the municipality where they reside. While in some parts of Switzerland these decisions are made by elected representatives, in other municipalities individual applications are subject to a public referendum. Dominik Hangartner and Jens Hainmueller assess the impact of direct democracy on citizenship applications, finding that far fewer applications are accepted when a referendum is used. The applicant’s country of origin is the most important factor in determining success, with applicants from Turkey and the former Yugoslavia over ten times more likely to be rejected than those from other countries, such as Italy.
