The poll, called “The Global Index of Religiosity and Atheism,” found that the number of Americans who say they are “religious” dropped from 73 percent in 2005 (the last time the poll was conducted) to 60 percent.
At the same time, the number of Americans who say they are atheists rose, from 1 percent to 5 percent.
The poll was conducted by WIN-Gallup International and is based on interviews with 50,000 people from 57 countries and five continents. Participants were asked, “Irrespective of whether you attend a place of worship or not, would you say you are a religious person, not a religious person, or a convinced atheist?”
The seven years between the polls is notable because 2005 saw the publication of “The End of Faith” by Sam Harris, the first in a wave of best-selling books on atheism by Christopher Hitchens, Richard Dawkins, Daniel Dennett and other so-called “New Atheists.”
“The obvious implication is that this is a manifestation of the New Atheism movement,” said Ryan Cragun, a University of Tampa sociologist of religion who studies American and global atheism.
