De Stemming 2023 (DS2023) is an online survey amongst a representative quota sample of N=2,092 respondents that live in the Flemish region of Belgium. As with previous iterations of the survey in 2020, 2021 and 2022, 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. Consequently, the topics covered in the survey concerned respondents’ political opinions and preferences, policy preferences, and attitudes towards democracy and politics. This survey took a deeper look at political dissatisfaction and distrust, as well as the topic of economic inequality. In addition, some questions about the nitrogen agreement and other topics were added to the survey given current events.
