These data are based on more than 320,000 interviews conducted by Gallup between Jan. 2 and Nov. 30 of this year. Similar data going back to 2008 form the basis of the new book God Is Alive and Well: The Future of Religion in America.
Sixty-nine percent of American adults are very or moderately religious, based on self-reports of the importance of religion in their daily lives and attendance at religious services. Within that group, 40% are very religious, meaning that they attend religious services regularly and they say religion is important in their daily lives.
