Identification of Cross-Country Similarities and Differences in Regulation of Religion Between 2000 and 2014 with Help of Cluster Analysis

Abstract

Building on previous quantitative and qualitative research on cross-country differences and similarities in regulation of religion, this paper employs data for 2000 and 2014 from the third round of the Religion and the State project and uses various cluster analysis techniques to identify country clusters based on the form in which countries regulate religion. The analysis separates between democratic and authoritarian countries. We further study if and how the clustering of the countries changes depending on the employed indicators and the employed cut-off points in defining democracy and autocracy. Overall, the results demonstrate the potential and limits of empirical classifications. In addition to the methodological and descriptive contribution, the results are compared and contrasted with previous work on state-religion relationships.
