In this repository we share all materials necessary to reproduce the statistical analyses as well as the original questionnaires and the supplemental document appended to the article. The repository contains the following folders:
- **01 Data**: This folder contains all data required to reproduce the results. The data sets include only variables which are relevant for the analyses.
- <code>ds19panel.rds</code>: Data of the first wave of the panel survey, conducted in June/July 2019
- <code>ds20panel.rds</code>: Data of the second wave of the panel survey, conducted in November 2020<sup>1</sup>
- <code>ds19cross_nopanel.rds</code>: Data of the cross-sectional survey conducted in June/July 2019, panelists excluded

<sup>1</sup> The survey weights contained in this data set (which were computed by the polling company) have been raked using Swiss census data. Hence, we relied on this data set (weighted) when comparing the sociodemographic characteristics of our panel sample with the Swiss population.
<sup>2</sup> We used these files to add inhabitant counts of respondents’ residence municipalities to the survey data. Inhabitant counts then served as a proxy measure for the degree of urbanity of respondents’ residence places.
