Ragin has made many contributions to sociology. He is a proponent of using fuzzy sets to bridge the divide between quantitative and qualitative methods. His main interests are methodology, political sociology, and comparative-historical research, with a special focus on such topics as the welfare state, ethnic political mobilization, and international political economy. He is also the author of more than 100 articles in research journals and edited books, and he has developed software packages for set theory analyses of social data, Qualitative Comparative Analysis (QCA) and fuzzy set Qualitative Comparative Analysis (fsQCA).

Ragin has been awarded the Stein Rokkan Prize of the International Social Science Council, the Donald Campbell Award for Methodological Innovation by the Policy Studies Organization, and received honorable mention for the Barrington Moore, Jr. Award of the American Sociological Association. He received the 2014 Paul F.
