Résumé : This work looks into the relationship between voters’ choice and issues in the 2019 Regional election. It seeks to answer the question of whether voters’ preferences in elections are driven by socio-economic or cultural factors. As a result, the main focus is on how socio-economic and cultural issues drove voters’ choice in the Brussels Regional Capital in the last election. Using data from RepResent Voter survey of 2019 I analyses how the following issues, employment, taxes, environments, social security, the economy, migration, crime, defense, and state reforms impact voters’ behaviour in the Brussels Regional Capital. I found out that though all the issues had an impact on voters’ choice; socio-economic issues had more impact on informing voters’ behaviour. Using the ages of respondents as a control I found that respondents of all ages were influenced more by socio-economic issues. Also, issue ownership was looked into to see if voters were aware of the issues political parties represented and voted for particular political parties based on the issues.
