"The survey finds a strong relationship between a country's religiosity and its economic status. In poorer nations, religion remains central to the lives of individuals, while secular perspectives are more common in richer nations.1 This relationship generally is consistent across regions and countries, although there are some exceptions, including most notably the United States, which is a much more religious country than its level of prosperity would indicate. Other nations deviate from the pattern as well, including the oil-rich, predominantly Muslim -- and very religious -- kingdom of Kuwait."Lot's more numbers in the report.
