Religion in the United States (2014 survey - Pew Forum)

Americans without a religious affiliation represent about 20% or more of the population and since the early 1990s, independent polls have shown their rapid growth. They include agnostics, atheists, deists,secular humanists, and general secularists.

Unaffiliated Americans are sometimes referred to as "Nones". Though having no religion and not seeking religion they have diverse views: 68% believe in God, 12% are atheists, 17% are agnostics; in terms of self-identification of religiosity 18% consider themselves religious, 37% consider themselves as spiritual but not religious, and 42% considers themselves as neither spiritual nor religious; and 21% pray every day and 24% pray once a month.

According to the Pew Research Center, in 2014, 22.8% of the American population does not identify with a religion, including atheists (3.1%) and agnostics (4%). According to the 2014 General Sociological Survey, 21% of the American population does not identify with a religion; furthermore, the number of atheists and agnostics in the U.S. has remained relatively flat in the past 23 years. In 1991, only 2% identified as atheist, and 4% identified as agnostic. In 2014, only 3% identified as atheists, and 5% identified as agnostics. The Nones tend to be more politically liberal and their growth has resulted in some increases in membership of secular organizations. However, the overwhelming majority of those without religion are not joining secular groups or even aligning with secularism.

Some of the underlying factors in the increases in people identifying as "Nones" seem to not be that significant amounts of people are dropping religion, but rather that, in recent times, it has become more socially acceptable for younger and older generations to identify as a "None" than in previous decades, when identifying as having no religion carried negative stigmas. With young people usually having lower religious observance than older people and them feeling more comfortable identifying as a "None", generational replacement factors could play a role in the increment.

Younger generations as a whole have lost trust and belief in numerous institutions along with religion. For instance, Millennials, which make up about 1/3 the "Nones" demographic, tend to have less belief and trust in institutions such as the labor market, the economy, government and politics, marriage, the media, along with churches; than previous generations.

A comprehensive study by David Campbell and Harvard University professor Robert Putnam found that religious Americans are three to four times more likely than their nonreligious counterparts to "work on community projects, belong to voluntary associations, attend public meetings, vote in local elections, attend protest demonstrations and political rallies, and donate time and money to causes -- including secular ones." However, religious Americans who regularly attend religious services but have no friends there do not have higher levels of civic participation, while nonreligious Americans who have religious friends do get more involved. "It's not faith" that accounts for civic activism, Putnam said, "It's faith communities." The authors said the same effect might be found in secular organizations that are close-knit with shared morals and values. The study also found that religious Americans are less tolerant than secular Americans of free speech, dissent, and several other measures of tolerance.
