A rise in secularism
Kosmin and Keysar came to Trinity more than four years ago to found the Institute for the Study of Secularism in Society and Culture. Kosmin, a Trinity research professor in public policy and law, is director and Keysar is associate director. They started the institute, Keysar says, when they realized an increasing number of Americans claim no religion.

Along with research, the institute puts on public events and works with various Trinity departments to develop curriculum materials.

The Census does not ask about religion because of concerns about the constitutional separation of church and state. The General Social Survey by the National Opinion Research Center at the University of Chicago uses such a tiny sample that smaller religions can’t be tracked. “You aren’t going to find many Rastafarians if you ask 1,200 people,” Kosmin says.
ARIS surveyed more than 54,000 people. (And found a jump in Wiccans from 8,000 to 342,000 in the past 18 years, for instance.) ARIS is also a bigger survey than the one conducted by the Pew Forum on Religion & Public Life.

The government’s official Statistical Abstract of the United States uses the Trinity survey for its religion table. Kosmin is proud of that and the fact that the data is in “public use”—meaning open for other researchers to use.
The ARIS survey gives a snapshot of both the beliefs and the religious identification of Americans, as well as how demographic and cultural forces have changed over time.
The percentage of people who said they were Christian has dropped—from
86 percent in 1990 to 76 percent 2008. Most of those “lost” Christians
entered the no-religion category. Catholics are the single largest U.S.
denomination, with a quarter of the population, followed by Baptists
with almost 16 percent. The no-religion group was the third-largest.
Challenges to the old way
Kosmin predicts that the number of people who list no religion at all will continue to grow. Many of them are young and could pass that along to their children. Other people are likely to leave the denominations where they belong now, he says.
