Introduction: German Party Membership in the 21st Century

The party membership decline experienced in Germany in the last decades raises a number of theoretical, empirical, and normative questions, a selection of which is addressed in this special issue of German Politics. In this introduction, we summarise some of the central arguments and findings presented. Although the individual articles take various perspectives and present specific insights, as a whole they allow for drawing some consequences: Firstly, party membership decline seems to be irreversible, secondly, it does neither imply an inadequate organisational linkage between society and state institutions nor, thirdly, a threat to democracy.
