In this chapter, we draw on the ActEU framework to examine the relationship between political representation and political trust in Austria. We focus on citizens’ subjective perceptions of representation (how citizens perceive being represented) across levels of governance. Bringing together newly compiled data on the sociodemographic characteristics of MPs and data from the ActEU public opinion survey, this study combines analyses of objective (descriptive and substantive) representation in the Austrian Nationalrat with subjective representation and examines how these perceptions relate to trust in political institutions. Our findings show that Austria has made gradual progress in descriptive representation, especially regarding gender, migration background, and openly LGBTQI+ representation; however, these developments are only weakly reflected in citizens’ subjective evaluations. Feelings of under-representation are widespread and unevenly distributed across social groups, with notable gaps by age, socio-economic position, and education. Perceptions of substantive representation also vary across policy agendas and across levels of governance (local, national, and European), revealing important mismatches between objective indicators and lived experiences. Trust in political institutions is generally moderate to low and closely linked to these subjective perceptions, though not always in straightforward ways. Group-specific and level-specific patterns of trust often diverge from both descriptive inclusion and parliamentary activity. Overall, the chapter highlights the central role of subjective representation in understanding political trust and democratic resilience. It shows that improvements in objective representation do not automatically translate into higher perceived representation and trust, underscoring the need to account for subjective perceptions when assessing the quality of representative democracy in Austria and beyond.
