This Element contributes to existing research with an analysis of public understandings of democracy based on original surveys fielded in Indonesia, Malaysia, the Philippines, Singapore and Thailand. It conceptualises democracy as consisting of liberal, egalitarian and participatory ideals, and investigates the structure of public understandings of democracy in the five countries. It then proceeds to identify important relationships between conceptions of democracy and other attitudes, such as satisfaction with democracy, support for democracy, trust in institutions, policy preferences and political behaviour. The findings suggest that a comprehensive analysis of understandings of democracy is essential to understand political attitudes and behaviours. Conceptions of democracy have implications for democratic legitimacy and political behavior.
