Duke University sociologist Mark Chaves' working title for his new book on trends in U.S. religion was "Continuity and Change in American Religion."
But the folks on the Princeton University Press marketing team suggested he could attract more attention with the bolder title: The Decline of American Religion.
Chaves, director of the National Congregations Study, took another look at research showing indicators of traditional beliefs and practices are either stable or falling in a nation that is a symbol of the staying power of religion in the West.
His conclusion: "The burden of proof has shifted to those who want to claim that American religiosity is not declining."
Chaves shared his perspective in a paper on "The Decline of American Religion?" for the Association of Religion Data Archives. His work is a significant addition to the discussion of the future of faith in the U.S.
The argument that religion is declining has gained more attention in recent years with major surveys pointing to the existence of a substantial group of Americans who state no preference for organized religion.
Fifteen percent of respondents to the 2008 American Religious Identification Survey did not identify with a religious group, up from 8 percent in 1990. The 2007 U.S. Religious Landscape Survey found 16 percent of respondents said they were unaffiliated with any particular faith today, more than double the number who said they were not affiliated with any particular religion as children.
But researchers also point out strong signs of stability, even steady growth over the long term, in American religious life.
"The single most significant trend in American religion from 1900 to the present has been the steady and spectacular decline in the percentage of religiously unaffiliated people in the American population," J. Gordon Melton, founding director of the Institute for the Study of American Religion in Santa Barbara, Calif., wrote in a recent ARDA paper on "American Religion's Mega-Trends." "In 1900, the religiously unaffiliated included some 65 percent of the population. That figure has now dropped to around 15 percent."
