Wave 1 was fielded in January (pre-campaign), wave 2 in May (campaign), wave 3 in June (post-electoral), and wave 4 in November (post-electoral). The dataset consists of separate samples for Brussels, Flanders, and Wallonia. The surveys focus strongly on affective polarization and perceptions of differentness.
