Replication Data for: How Education Policies Shape Political Inequality: Analyzing Policy Feedback Effects in Germany

Education is one of the strongest predictors of political participation at the individual level. However, the association between education and participation varies across countries, which previous studies attribute mainly to institutions such as electoral systems and welfare states. Drawing on policy feedback and political socialization theories, we suggest an alternative explanation: education policies generate powerful and lasting policy feedback effects in adolescence, which continue to influence patterns of participation among adults. More concretely, we argue that policies aimed at de-stratifying secondary education (i.e. promoting more comprehensive models of education) are associated with a decrease in political inequality. We empirically investigate our argument in Germany, where education policies vary across subnational units (Länder) and over time. We leverage this variation by combining data on education policies at the Länder-level with data on individuals’ political participation. Our results show that de-stratifying education policies have reduced political inequality.
