I earlier posted a PDF with some interesting international statistics in my Norwegian blog, but the charts are easy to grasp and there's a brief explanation in English under each chart too:
First of all, the PDF is a combination of two studies: 1. ROSE (The relevance of science education) (International, 15 yearolds) og 2. The Eurobarometer. (Europe, grown-ups). You'll most likely find the information elsewhere in English if you need it, but the charts can be enlightening.
Read more about ROSE here in English.
I'll breiefly explain what the charts shows
Part 1. Rose (15 yearolds, international)
Page 8: Mean H28. taken herbal medicines or had, alternative treatments (acupuncture, homeopathy, yoga, healing, etc.)
A little difference between genders, but Northern Europe are the least interested and Africa the most.
Page 9: Mean C12. Interest for alternative therapies (acupuncture, homeopathy, yoga, healing, etc.) and how effective they are.
In this chart, you'll see a very big difference between the genders in Europe. Boys have little interest while
girls have more interest than both women and men in the third world countries.
Page 10: Mean H2. read my horoscope (telling future from the stars)
Also very big differences between the genders all over Europe. Almost all girls have read it. In Africa, there's little difference bwteen the genders, and they all read the horoscope less than European girls
Page 11: Mean C9. Interest for astrology and horoscopes, and whether the planets can influence human beings
While European girls still are much more interested than men, it is nowhere near the same as having merely read the horoscope. African countries top the score here.
The rest pretty much explain themselves
Page 12: Mean C11. Interest for life and death and the human soul
Page 13: Mean C13. Interest for why we dream while we are sleeping, and what the dreams may mean
Page 14: Mean C14. Interest for ghosts and witches, and whether they may exist
Page 15 Mean C15. Interest for thought transference, mind-reading, sixth sense, intuition, etc.
Page 16: Mean E34. Interest for why religion and science sometimes are in conflict
This is an interesting chart. It can be interpreted in two ways. Say, in Norway, most youths are not interested in learning about this. Is it because they're less religious over all, or is it because religion here is more adapted to the scientific outlook, and the conflict is less obvious than elsewhere?
Part 2: Eurobarometer, (grown-ups, Europe)
(Some of the questions are normal health questions and I'll skip them)
Page 26: Praying? (last year, to cure a health problem)
This is the graph I posted on top here.The numbers are all over the place, but women are always praying the most.
