Abstract This study examines whether younger generations are more likely to associate their support for European unification with cultural, rather than economic issues. The EU has changed from an ‘economic community’ to a ‘political union.’ Because most citizens form relatively stable orientations during their ‘impressionable years,’ we expect recent generations to be more likely to view European unification through a cultural lens. An analysis of 12 waves of panel data from the Netherlands finds the strongest correlation between EU support and cultural attitudes among the newest generations. However, these generations are not less likely to associate EU support with economic attitudes. Moreover, between 2007 and 2019, Euroscepticism became increasingly associated with cultural attitudes among all generations and age groups. These findings indicate that EU support has become more strongly aligned along a cultural dimension and that this realignment will become more pronounced as newer generations replace earlier ones.
