Religious Polarization in Europe

We define two types of religious polarization and investigate the extent to which they are present across European countries, based on data from the 2008 to 2017 European Values Study and hierarchical linear modeling. The first type is polarization by religiosity, with declines in the middle ground between the actively religious and the nonreligious as secularization reaches an advanced stage. The second type is issue polarization, with the religious and secular taking different positions on a range of socio-political values, including social conservatism and ethnic nationalism. We find limited evidence of bimodality in the distribution of religiosity. We find more evidence, however, of issue polarization between the religious and secular in Europe, especially in social conservatism. Religious polarization should thus be understood as a multidimensional concept where one dimension may be more prevalent than others in society.
