Fewer Americans are keeping the faith compared to previous years, according to a new poll released on Tuesday.
The survey, conducted by Pew Research Center, looked at church attendance, prayer and belief in God.
Those who had an absolute certainty of the existence of a higher power dropped to 63 percent in 2014 from 71 percent in 2007.
The trend is higher among young people — particularly millennials — who are less likely to attend religious services. Only 39 percent are likely to pray daily.
Both the 2014 and 2007 studies surveyed more than 35,000 adults.
