This article is a review of the recent literature on generational differences in electoral behaviour. We first discuss several conceptual issues, after which we provide a description of the main findings in three fields: the role of generations in (1) turnout, (2) party choice and (3) the determinants of party choice. In the concluding section we discuss a number of overall patterns that emerge from this very rich literature. We also sketch some pitfalls and avenues for further research.
