The chapter focuses specifically on civic engagement as a distinct mode of political activity among citizens in contemporary democracies. In the first section, we review existing definitions of “civic engagement” in the literature, noting in particular the lack of common notions of what it entails, as well as the critique against too wide or all-encompassing definitions. In the second section, we develop a conceptual discussion about civic engagement and political participation, and suggest a thin notion of civic engagement that may be measured in a straightforward way in empirical studies. In the third section, we turn to an overview of recent empirical works on civic engagement, highlighting key findings and suggesting avenues for further research.
