The Effect of Compulsory Voting on Turnout Stratification Patterns. A Cross-National Analysis

As voter turnout is steadily declining in Western democracies, various authors have expressed concern about the stratification in electoral participation that this trend might entail. Some research suggests that specific categories of potential voters refrain from voting, leading to the electoral dominance of more privileged groups within the population. In this article, we investigate whether systems of compulsory voting are associated with more equal participation in elections. We study 36 countries that participated in the 2004 International Social Survey Programme. The analysis shows that compulsory voting is associated with higher turnout rates, but we do not observe any significant differences in electoral participation based on gender or educational level. However, we find a significant interaction effect between age and compulsory voting, suggesting that young age cohorts are unlikely to be affected by the dynamics of the civic duty argument that is inherent in systems of compulsory voting.status: publishe
