Measuring the size and scope of the EU interest group population

Abstract: We present a new data set enumerating the population of organizations listed and/or registered as lobbyists in the European Union. In the first part of the paper we describe how we arrived at the population data set by drawing on three independent sources (CONECCS; Landmarks; European Parliament registry). We briefly discuss the validity of these registers in the context of recent substantial changes to each of them. In the second part, we present descriptive information on the number and type of groups as well as their territorial origins. In the final section, we outline potential research questions that can be addressed with the new data set for further research on the role of groups in the EU policy process.
