In a previous post, I described my use of the World Values Survey (WVS) and European Values Study (EVS) to develop a measure of pre-modern religious values (approximately corresponding to “fundamentalism”). I have used this to calculate the prevalence of pre-modern religious values using data from waves 5-7 of the surveys, covering the period 2005-2020, but with most results relating to the recent decade 2010-2020. I somewhat arbitrarily chose a cutpoint of 6.45 on the religious values scale to classify people as having pre-modern values (<6.45) versus modern values (>=6.45). The value 6.45 was chosen as the point where the distribution of scores for individuals 2 and 3 (described in the previous post) crossed over.
The following graph shows the prevalence of pre-modern values (as % of adult population) for countries in waves 5-7, ranked from lowest (Denmark at 13% and Sweden at 14%) to highest (Bangladesh, Myanmar and Qatar at 100%).
