I wonder if you have ever been to Denmark, Sweden and Japan the countries you mentioned as examples?
I haven't visited these countries so rely on what people say and write about them.
The most secular country with which I am familiar is New Zealand. In the last 27 years religion has become less important in people's lives, and few seem have any attachment to anything that is religiously based.
According to Wikipedia Christianity is the predominant religion in New Zealand at just over half of the population at the 2006 New Zealand Census,[82] although regular church attendance is probably closer to 15 percent.[
I suspect that the census records reflect a rather shallow view of people's religious affiliations.
My remark still stands: "It might be an interesting and educational experience for you to do some historical research into the list of communities throughout history that have prospered and grown with a strong declaration and belief system of no religion, no superior-being and no idols, holy scriptures and holy ceremonies... "
Nothing yet... and not holding my breath. Have you come across anything?
The downtrends in people claiming religious affiliations in many countries is interesting, and the same question asked in say fifty years from now may be easier to answer. Only time will tell.
