Scope of Survey
The survey was online from 8 April 2020 to 10 May 2020. The majority of responses were collected between 12 April and 16 April 2020. A total of 6,919 people responded to one of the four translated versions (French, German, English and Italian). The questionnaire was shared via an EPFL press release to mainstream media in Switzerland, the EPFL website page, social networks of the various institutions involved and researchers’ personal networks.
Geographical distribution of responses
The survey for the Swiss resident population travelled across borders and collected responses from all over the world. However, 91% of responses came from people residing in one of the country’s 26 cantons. To avoid mixing health and social situations that were too different, the results given here are only from residents of Switzerland, regardless of their nationality.
Distribution of responses by canton
The Canton of Vaud was the most active in survey responses, followed by the canton of Geneva, Valais, Friborg and Neuchâtel. The French-speaking region was predominant in the questionnaire period, with 91% of responses given in French. To a lesser extent, Bern, Zurich and Ticino are also represented.
