De Stemming 2020 (DS2020) is an online survey amongst a sample of N=2,040 respondents that live in the Flemish region of Belgium. The survey was developed by Jonas Lefevere and Stefaan Walgrave on the request of the Flemish public broadcaster (VRT) and the newspaper De Standaard, to analyse Flemish public opinion one year after the 2019 general elections in Belgium. Consequently, the topics covered in the survey concerned respondents’ political opinions and preferences, policy preferences, and general attitudes towards democracy and politics. Given that the survey was conducted in the middle of the peak of the Corona / COVID-19 pandemic, the survey also included an additional bloc of questions concerning support for the emergency measures taken, as well as the government’s handling of the crisis.
