A Study of the Evolution of Religiosity in Western European Societies from 1980 to 2010

Examining the role of religion and the evolution of religiosity in Western European societies, as secular societies, has always been important. Given the period from 1980 to 2010, this article seeks to answer the question of what changes religiosity has undergone in Western European societies, especially in the two dimensions of belief in religion and practice of religious beliefs. To answer this question, we have used the survey method and data analysis. In this regard, a survey program entitled "Study of European Values" examined the ideas, attitudes and values ​​of citizens in various fields including religion and religiosity since 1981 and in the form of five study waves (1981, 1990, 1999, 2008 and 2017). The survey data have been used in this article to explain and analyze the discussion. Considering indicators such as theism, religious rites, church attendance rate and adherence to traditional rituals in important matters of life (birth, marriage and death), the findings of this study show that the process of secularization in Western European countries, both in terms of belief in religion and in terms of practice of religious beliefs, has intensified and the role of religion in the lives of Western European societies is much more declining than before.
