For the first time in history, atheists constitute the largest religious group in America. According to the General Social Survey, the number of Americans who have no religion has increased 266% over the past three decades and now account for 23.1% of the population, just barely edging out Catholics and Evangelicals as the nation’s dominant faith. Mainline Protestant churches have suffered the greatest collapse, declining 62.5% since 1982 and now comprising just 10.8% of the U.S. population.
