Fig. 7: Development of participation, importance of religion, and belonging in theoretical time.
From: The three stages of religious decline around the world
WVS/EVS 1-7 data. We show 17 countries that were surveyed 5 times or more often, except eastern post-communist countries. Colored lines show the development of percentage of weekly participation, high importance of religion and religious belonging over time modeled with linear models. Country positions are found by shifting the countries towards the left or right according to their overall religiosity, multiplied by an expansion factor lambda.
