Replication Data for: Municipality-Level Outcomes of Direct-Democratic Votes in Switzerland, 1866-2023

Abstract: Switzerland relies heavily on direct-democratic institutions to decide on a wide range of political issues. Since 1848, more than 600 direct-democratic votes have taken place at the national level. However, the lack of comprehensive data has limited the systematic use of these votes for research. This paper introduces a new dataset containing municipality-level outcomes for all direct-democratic votes from 1866 to 1944, and supplements post-1945 data to fill gaps in previous collections. Spanning over 150 years, the new dataset contains more than 1.3 million observations. Several empirical illustrations demonstrate the dataset’s potential for research.
