Whereas research on political participation typically investigates a variety of socio-economic and attitudinal characteristics, this cross-national study focuses on the relevance of norms when explaining political participation. We examine respondents' normative beliefs about the importance of various measures of ‘good citizenship’, and their relationship to three modes of political engagement (activism, party membership and voting). We find assigning higher importance to paying taxes/obeying the law is negatively linked to all forms of participation, whereas the opposite is true for norms about the importance of voting and being active in associations. Greater emphasis on norms about understanding others and shopping politically is positively associated with political activism but not with more institutional forms of participation. The relationship between norms and participation differs somewhat across nations, with the most differences between Eastern European respondents and those from Western European and Western non-European respondents. In line with theories on democratic learning, we find that the relationship between citizenship norms and participation is often weakest among Eastern Europeans. Conclusions about the subjective and variable nature of democratic citizenship are discussed.
