The Individual-Level Determinants of German Party Membership

Why do citizens join German parties? Do specific attributes and abilities play a determinant role in participation in political parties? The German Party Membership Study of 2009 enables us to answer these questions. On the basis of the telephone survey, we will address these issues by way of a systematic comparison of current party members with fellow citizens who never joined a party. For the purpose of analysing the individual-level determinants of joining a party, we use fundamental explanatory approaches to political participation: The socioeconomic standard model, the social-psychological approach, and the general incentives model. The results of our analyses clearly show that social-psychological attributes best explain the decision to join a party. Nevertheless, the findings for the determinants in both the socioeconomic standard model and the general incentives model complete the picture of citizens who are party members
