It's not unusual to hear commentators, especially religious conservatives, dismiss secular activism by citing numbers, pointing out that only one or two percent of Americans identify as atheists.
Though technically correct, such numbers only tell half the story.

The American Religious Identification Survey (ARIS) - probably the most comprehensive study of American religious demographics - confirms that only about 1.6 percent of Americans identify as atheist or agnostic. This may seem like an insignificant group, but even just 1.6 percent outnumbers the population of American Mormons (1.4 percent), Jews (1.2), Episcopalians (1.1), Muslims (0.6), and many other groups. Much more importantly, however, we should realize that the 1.6 percent figure is deceiving, because ARIS also shows that the actual number of nonbelievers is much higher.
