Number of Americans Without Religious Affiliation on the Rise

George Doyle/Thinkstock(NEW YORK) -- Nearly 20 percent of Americans do not identify with any particular religion, according to a new poll. The number is much higher among younger Americans, according to the survey from the Pew Forum on Religion and Public Life.

For the first time less than half of Americans – 48 percent – consider themselves to be Protestant. One third of Americans under 30 do not identify with a religion. Pew calls them “nones.”

In 1972, only 7 percent of Americans did not identify with a religion, according to Pew.

The number of Christians has fallen by 5 percent, according to the survey. Those affiliated with “other religions” has risen by more than 2 percent. And the number not identifying with a particular religion has gone up more than 4 percent since 2007.

Those without a specific religion are not necessarily nonbelievers. In fact most of them do believe in a higher power of some kind. About 30 percent of the “nones” are “absolutely certain” there is a God or universal spirit. Seven percent of the U.S. population and 27 percent of those not affiliated with a religion believe there is no God or universal spirit.

The number of Americans who attend church “seldom or never” has climbed from 25 percent in a 2003 Pew survey to 29 percent today.

All this paints an interesting picture of American religious life, and according to the survey, could have political consequences. “Nones” seem to favor Democrats.

Here is a passage from Pew’s report:
With their rising numbers, the religiously unaffiliated are an increasingly important segment of the electorate. In the 2008 presidential election, they voted as heavily for Barack Obama as white evangelical Protestants did for John McCain. More than six-in-ten religiously unaffiliated registered voters are Democrats (39%) or lean toward the Democratic Party (24%). They are about twice as likely to describe themselves as political liberals than as conservatives, and solid majorities support legal abortion (72%) and same-sex marriage (73%). In the last five years, the unaffiliated have risen from 17% to 24% of all registered voters who are Democrats or lean Democratic.

Democrats may do better among those not identifying with religion, but it is still quite difficult to be an elected official in the United States as an atheist. A Pew study in 2011 found that 61 percent of Americans would be less likely to support a candidate that didn’t believe in God. Only 46 percent would be less likely to support a candidate that had an extramarital affair.

There is only one member of Congress who considers himself an atheist – Rep. Pete Stark of California.
