Americans go to church less but the rate of departure previously reported may have been incorrect, according to sociologists Michael Hout and Claude S. Fischer of the University of California, Berkeley.

According to the new data, 93 percent of Americans believe in God, a figure unchanged since 1988. The group that increased was the group Hout and Fischer call "unchurched believers," those people who believe in God but report no religion. 

Their research presented at the 104th annual meeting of the American Sociological Association found that the previous estimate of 'unchurched believers' proportion doubling during the 1990s was probably instead including results from earlier than 1991 and therefore doubled over a 14- or 15-year period. Their new data suggest that the trend continued through 2008, likely fueled at least partially by the growing number of Americans who were raised with no religion. 

"If you think of organized religion as having two parts—the organized part and the religious part—the church-leavers' quarrel is with the organized part," said Michael Hout, professor of sociology at the University of California, Berkeley, and the lead author of the study. 

As they originally reported in 2002(1), Hout and Fischer assert that politics continue to play a role in the increase in those reporting no religion preference. The sociologists seek to correlate the rising rates of non-religious Americans with political affiliation.   Political liberals and moderates are much less likely to report a religion now than in 1988; almost all political conservatives identify with a church now as they did twenty years ago.

Americans expressed stronger anti-religious feelings in 2008 than in 1998. For example, two-thirds of adults agreed that "religion brings more conflict than peace" in 2008 compared with just one-third in 1998. Similarly more Americans described themselves as "non-religious" in 2008 than in 1998.

Among the rising number of Americans who cite no religious preference, those who believe in either God or the afterlife outnumber those with no beliefs. In addition, the number of religiously affiliated non-believers declined sharply between 1973 and 2008.

The General Social Survey is conducted by the National Opinion Research Center and funded by the National Science Foundation.   Hout and Fischer presented their research, "The Politics of Religious Identity in the United States, 1974-2008," on Sunday, Aug. 9, at 8:30 a.m. PDT, in the Hilton San Francisco at the American Sociological Association's 104th annual meeting.
