UNDATED (WTVB) - Fewer Americans are calling themselves "religious" these days.  According to a new worldwide poll conducted by WIN-Gallup International, 60 percent of Americans say they would call themselves "religious."  That's a 13 percent drop-off from the 73 percent who said so last time the same poll was conducted in 2005.  Similarly, the number of Americans who say they are atheists jumped from one percent to five percent in the new poll.  The results are based on interviews with 50-thousand people from 57 countries worldwide.  Those polled were asked if they would say they were "a religious person," "not a religious person," or "a convinced atheist," regardless of whether they attend a place of worship.  The poll found the decline in religion is both a national and worldwide trend.
