Researchers agree that religiosity in the U.S. is in the midst of a “great decline.”

Although religious belief has been on the wane for some time now, 2013 was new low.

From RSFRS:

The graph of this index tells the story of the rise and fall of religious activity. During the post-war, baby-booming 1950s, there was a revival of religion. Indeed, some at the time considered it a third great awakening. Then came the societal changes of the 1960s, which included a questioning of religious institutions. The resulting decline in religion stopped by the end of the 1970s, when religiosity remained steady. Over the past fifteen years, however, religion has once again declined. But this decline is much sharper than the decline of 1960s and 1970s. Church attendance and prayer is less frequent. The number of people with no religion is growing. Fewer people say that religion is an important part of their lives.
