Atheism in the U.S. IS GROWING! However, it seems to just be compounding the fact that you are, quite literally and collectively, "LOST". Look at these numbers from a Pew Research poll from 2012... The number of people who identify themselves as atheists in the United States has been rising, modestly but steadily, in recent years. Our aggregated data from 2012 show that 2.4% of American adults say they are atheists when asked about their religious identity, up from 1.6% in 2007. Although the literal definition of “atheist” is “a person who believes that God does not exist,” according to the Merriam-Webster dictionary, 14% of those who call themselves atheists also say they believe in God or a universal spirit. That includes 5% who say they are “absolutely certain” about the existence of God or a universal spirit. Alternatively, there are many people who fit the dictionary definition of “atheist” but do not call themselves atheists. More Americans say they do not believe in God or a universal spirit (7%) than say they are atheists (2.4%).
