Americans over the years have generally been more likely to say religion is losing rather than increasing its influence in American life. In addition to the previous peak in views that religion was losing its influence measured in 1969 and 1970, at least 60% of Americans thought religion was losing its influence in 1991-1994, in 1997 and 1999, in 2003, and from 2007 to the present.

Americans were more likely to say religion was increasing rather than decreasing its influence when the question was first asked in 1957, in 1962, at a few points in the 1980s during the Reagan administration, after the 9/11 terrorist attacks in late 2001 and early 2002, and in 2005. The high point for Americans’ belief that religion is increasing its influence, 71%, came in December 2001.

These perceptions of religion’s influence in American society are not related to Americans’ personal religiosity, as measured by church attendance or the self-reported importance of religion in one’s life.
