But yes, the United States is an exception:
About two-thirds of Americans -- 65% -- say religion is important in their daily lives. Among high-income countries, only Italians, Greeks, Singaporeans, and residents of the oil-rich Persian Gulf states are more likely to say religion is important.
Incredibly (and interestingly), only 17% of Swedes say religion is an important part of their lives, as do 19% of Danes. Yet these are among the most peaceful, socially advanced countries in the world. Food for thought.
