The Comparative Interest Group-survey project: design, practical lessons, and data sets

Abstract

AbstractThis article discusses the methodology and practice behind planning and executing the Comparative Interest Group-survey project (CIG-survey). The CIG-survey includes surveys among national populations of organized interests in 9 European countries and at the European Union level. Although surveys are a useful and reliable way to collect data on a variety of topics, there are also numerous pitfalls and challenges in surveying interest groups, especially across multiple countries. Despite the prominent use of surveys in interest group research, systematic reflections on this method are scarce and data sets are not always properly archived or openly accessible. This article elaborates upon the practical implications and reflects on the lessons learnt during from the implementation of the CIG-survey. Moreover, we highlight how the fuzzy boundaries of interest communities obfuscate sampling and that surveying interest organizations requires researchers to navigate through a specific organizational context to reach and motivate respondents. We also demonstrate how a careful survey plan can positively affect response rates and enable the creation of robust comparative data sets.
