Among developed nations, America stands out as an exceptionally religious country. While other wealthy nations grow ever more secular, the U.S. remains devoted to religion. New research on religion, however, finds that the U.S. may not be so exceptional after all.

The U.S., for all its wealth, is also a land of vast economic inequality.

Early sociologists saw society moving through an inevitable process of secularization. Eventually, went the theories, society would rid itself of the remnant of primitive superstition. Such theorists are still waiting for their Godot. Despite incredible rises in education, science, medicine, and overall quality of life during the 20th century, religion remains a common part of life around the globe.
