Survey: One in five Americans has no religion

Editor's note: CNN recently won four first-place reporting awards from the Religion Newswriters Association. Read more about the awards here.

By Dan Merica, CNN

Washington (CNN) – The fastest growing "religious" group in America is made up of people with no religion at all, according to a Pew survey showing that one in five Americans is not affiliated with any religion.

The number of these Americans has grown by 25% just in the past five years, according to a survey released Tuesday by the Pew Forum on Religion and Public Life.

The survey found that the ranks of the unaffiliated are growing even faster among younger Americans.

Thirty-three million Americans now have no religious affiliation, with 13 million in that group identifying as either atheist or agnostic, according to the new survey.

Pew found that those who are religiously unaffiliated are strikingly less religious than the public at large. They attend church infrequently, if at all, are largely not seeking out religion and say that the lack of it in their lives is of little importance.

And yet Pew found that 68% of the religiously unaffiliated say they believe in God, while 37% describe themselves as “spiritual” but not “religious.” One in five said that they even pray every day.

John Green, a senior research adviser at Pew, breaks the religiously unaffiliated into three groups. First, he says, are those who were raised totally outside organized religion.

Survey: Protestants no longer majority in U.S.

Second are groups of people who were unhappy with their religions and left.

The third group, Green says, comprises Americans who were never really engaged with religion in the first place, even though they were raised in religious households.

“In the past, we would describe those people as nominally affiliated. They might say, 'I am Catholic; I am a Baptist,' but they never went" to services, Green says of this last group. “Now, they feel a lot more comfortable just saying, ‘You know, I am really nothing.’ ”

According to the poll, 88% of religiously unaffiliated people are not looking for religion.

“There is much less of a stigma attached" to not being religious, Green said. “Part of what is fueling this growth is that a lot of people who were never very religious now feel comfortable saying that they don't have an affiliation.”

Demographically, the growth among the religiously unaffiliated has been most notable among people who are 18 to 29 years old.

According to the poll, 34% of “younger millennials” - those born between 1990 and 1994 - are religiously unaffiliated. Among “older millennials,” born between 1981 and 1989, 30% are religiously unaffiliated: 4 percentage points higher than in 2007.

Poll respondents 18-29 were also more likely to identify as atheist or agnostic. Nearly 42% religious unaffiliated people from that age group identified as atheist or agnostic, a number far greater than the number who identified as Christian (18%) of Catholic (18%).

Green says that these numbers are “part of a broader change in American society.”

“The unaffiliated have become a more distinct group,” he said.

Pew's numbers were met with elation among atheist and secular leaders. Jesse Galef, communications director for the Secular Student Alliance, said that the growth of the unaffiliated should translate into greater political representation for secular interests.

“We would love to see the political leaders lead on this issue, but we are perfectly content with them following these demographic trends, following the voters,” Galef said.

“As more of the voters are unaffiliated and identifying as atheist and agnostics, I think the politicians will follow that for votes.

“We won’t be dismissed or ignored anymore,” Galef said.

The Pew survey suggested that the Democratic Party would do well to recognize the growth of the unaffiliated, since 63% of them identify with or lean toward that political group. Only 26% of the unaffiliated do the same with the Republican Party.

"In the near future, if not this year, the unaffiliated voters will be as important as the traditionally religious are to the Republican Party collation,” Green predicted.

Green points to the 2008 exit polls as evidence for that prediction. That year, Republican presidential nominee John McCain beat President Barack Obama by 47 points among white evangelical voters, while Obama had a 52-point margin of victory over McCain among the religiously unaffiliated.

According to exit polls, the proportion of religiously unaffiliated Americans who supported the Democratic presidential candidate grew 14 points from 2000 to 2008.

In announcing the survey’s findings at the Religion Newswriters Association conference in Bethesda, Maryland, Green said the growing political power of the unaffiliated within the Democratic Party could become similar to the power the Religious Right acquired in the GOP in the 1980s.

“Given the growing numbers of the unaffiliated, there is the potential that that could be harnessed,” he said.

      Americans have been deliberately "dumbed down" and reprogrammed by television to believe in some pretty silly stuff. I think it's a sad state of affairs to think you live in a world of ghosts watching your every move. No wonder the right to privacy means so little to so many.

      @DK: yeah religion teaches it's ok to giev your daughter to an angry mob to save your visitors.
      it teaches it's ok to hate people not like yourself. the whole US vs. THEM mentality.
      it teaches whatever the preacher/holyman wants to say it saids.

      morals are set up by the people not by any god.
      bible said it's ok to beat slaves, thus it's ok to own slaves. humans decided it was a barbaric practice and made it illegal to own another human being.

    I've never understood how you can believe in God but say you're not religious. Where did your god come from if not religion? Unless, of course, you've seen him in person and had a chit-chat with him. If not, you've bought into religion hook, line, and sinker.

    Just because I am an atheist doesn't mean that I don't live by similar teachings as a Christian. We ALL have a moral compass whether religious or not. I don't need a religion to teach what is right and what is wrong. As a human and a member of this earth I can figure it out on my own.

    Common sense tells us that matter cannot organize itself. It needs information to do that, and information is a manifestation of intelligence (God).

      Information is just an arrangement of atoms. If (when) the right ones happen to come together, it creates a self-replicating chemical that evolves into things like dogs and bears and people. Easy cheesy.

      What I think you are referring to are natural laws, which all matter must abide by. You can personify this concept as "intelligence" if it helps you sleep at night, but I suspect this deist-like view you espouse is far more generic than what your actual religious views are...

      @Old School. You have pointed out the very point in believing in God. We ALL were created by somone greater than us. God has NO creator, He has NO begining, He has NO end. That is what makes Him God. If man could completly understand and explain God, then he really wouldn't be God. Even if you believe in Evolution, we must admitt it was Started By Something/Someone. And the GREAT part about God is that He wants to have a peraonal relationship with YOU. Forget this religion, that religion, God wants to have a perosnla relationship with you.

      October 9, 2012 at 11:13 am |
    • JeramieH

      So it's ok for God to exist without a creator, but it's lunacy to think that anything else can exist without one? Interesting doublethink there.

    Very interesting discussion. To me it's quite simple. Religion is a fabrication based on the concept of spirituality. The problem with religion is that it is largely man-made and therefore subject to the self-serving nature of man-made things. Spiritaulity, on the other hand, exists as a vast potential within each and every one of us to connect not only to our selves but to life as a whole in a way that brings us a profound sense of oneness with life as well as with each other. This oneness is at the heart of it all. Religion divides, spirituality unites. A modern day prophet predicted an end to the word of God and a return to an "age of reason," Nothing could sound more beautiful to me since I see an end to the wod of God as an end to the deceiptful word of man and a return to an age of reason as a return to our sacred, spiritual roots.

    It's about time. This is a good thing. This religion thing has been way out of hand for millenia. Even worse are all the organizations that have harnessed religion in the name of power. Some of the worst events in history have been precipated by religion. The Inquisition, etc. This is still going on. There is tremendous corruption in the largest churches. The fact is we are human and we can not cause to exist that which we only wish for.

      Mankind had a selfish,destructive lust for power. We will use any organization of groups to dominate another group. Religion is just a conveinet scapegoat used by dictators to unify people. Man kind used well meaing ideas and twist them to his end. Whether Christinaty or Communism, Islam or "States Rights", when it leads to blood shed and brutality the blame lies at the feet of man.

    I would like to agree with all those (athiests and agnostics) who feel their beliefs should be recognized by the politicians. Since 22% identify themselves as Catholic and 48% identify themselves as Protestant, the overwhelming majority of Americans (70%) are Christian. If a presidential candidate won 70% of the vote, would call that a clear mandate for change. Thank God most Christians (like myself) are more tolerant than our bothers and sisters who have no belief in God. If we were as insistent on imposing our belief system on you as you are in preventing us from expressing our beliefs, you would be in a terrible position. God Bless America!!

      You said, "Thank God most Christians (like myself) are more tolerant than our bothers and sisters who have no belief in God."
      You call forcing your delusions of your imaginary friend on the rest of society "tolerant"? If most christians were tolerant, we wouldn't have any references to your imaginary friend on our currency or the pledge of allegiance, or in or on public buildings. If most christians were tolerant, they would accept that not everyone believes in imaginary friends, and would keep their gods out of public places.

      You said, "If we were as insistent on imposing our belief system on you as you are in preventing us from expressing our beliefs, you would be in a terrible position."
      You are free to believe whatever nonsense you want. You are free to believe in whatever imaginary friend you feel like. You are free to worship any creature you fancy. But you are not free to expect anyone else to do the same. You are not entitled to force it on anyone else.

      Not wanting any part of your delusion isn't preventing you from expressing your beliefs. All I ask is that you do it with your own resources. Keep your delusion out of my life, and out of the lives of my children. Keep your nonsense in your private home and houses of worship.

      The fact that we still have references to your imaginary friend on public property is clear evidence that christians are still forcing their beliefs on the sane part of society.
