Religiosity in Europe: an index, factors, and clusters of religiosity

This paper has three aims. The first aim is to measure religiosity across all European countries through an index that combines beliefs, practices, and attitudes. The second aim is to analyse the strength of societal factors on religiosity, including modernisation, communist rule, national identity, religious pluralism, and religious freedom. The final aim is to group European countries by religiosity and to characterise each cluster by dominant religions and these five societal factors. Based on EVS 2008, it was applied multivariate analysis to reach these aims. Cluster 1 is mainly composed of Orthodox, Muslims, and Catholics; cluster 2 of Catholics, Orthodox, and people without religion; cluster 3 by people without religion, Protestants, and Catholics. Across clusters, the degree of human development, religious pluralism, and religious freedom increase, while the degree of national identity decreases.
