Last year, I posted the results of the General Social Survey showing that, in 2012, 20% of American adults reported themselves as having “no religion,” and that these folks—referred to by demographers as the “nones”—are increasing by about .6% per year. This month, the Pew Research Group released the results of their 2014 Religious Landscape Study. This survey, undertaken every seven years, is based on the results of a quota sample of over 35,000 adults and has a margin of error of plus or minus .6%. Although Pew refers to their nones as “unaffiliated,” the results are strikingly consistent.

Pew reports that 22.8% of the population were nones in 2014, up 6.7% from 16.1% in 2007. Meanwhile, those calling themselves Christians declined from 78.4% to 70.6%. This amounts to an increase of 19 million nones, for a new total of 56 million. Among all religious groups, the nones are second in size only to evangelical Protestants. A followup question showed that, of this 22.8%, 3.1% said they were atheists, 4% claimed to be agnostic, and 15.8% believed “nothing in particular.” This leaves open the possibility that some of the nones engage in spiritual practices, pray, or believe in one or more gods. There was also a 6% increase in those saying that religion is “not too” or “not at all important” in their lives.

The Pew researchers offer two explanations for this shift.

• Generational replacement. The most dramatic increases in the percentage of nones occurred among younger adults. However, they increased across all generations, even rising by 2% among people over 70.
• Switching religions. Among those who report switching their religious affiliation, the nones showed the largest gains of any group. Eighteen percent of Americans who were raised in a religious faith now claim to be unaffiliated.

Another perspective on this trend comes from the 2015 State of Atheism in America, a study by the Barna Group. It combines the results of four surveys of 23,000 adults conducted in 2011 through 2014. The Barna Group calls their nones the “unchurched,” meaning that they say they haven’t attended church in the last six months. This results in a larger group, about 36% of the total. They find that 25% of the unchurched are either atheists or agnostics, a group they call “skeptics.” I find this a more interesting group than folks who believe “nothing in particular,” since they would seem to have given some thought to religion.

The Barna Group identifies five demographic shifts among their skeptics when they are compared to the same group in a 1993 survey they conducted.

1. They are younger. In fact, 34% of them are between 18 and 30.
2. They are more educated. Half of them are college graduates. Only 32% of Americans over 25 have graduated from college.
3. A higher percentage are women. Male skepticism increased too, but not as much as among women.
4. They are more racially diverse. This is due largely to an increase in skepticism among Hispanics and especially Asians.
5. They are more regionally dispersed. The Northeast and West continue to have higher percentages of skeptics, but the differences are not as great as in the past.

The last three trends suggest a mainstreaming of skepticism. Rather than being a distinctive subgroup, atheists and agnostics are becoming more broadly representative of the population. One major exception, however, is the continuing underrepresentation of African-Americans.

The Barna Group’s stated goal is to reconnect with skeptics and bring them back under the influence of superstition, so they asked skeptics what they thought of Christian churches. They note four common responses, although they don’t report the percentages who gave each one.

1. The church is group of people who share a physical space but are not otherwise connected to one another in meaningful ways.
2. The church adds little of value to their community.
3. The church stands for the wrong political policies: war, sexual and physical violence, prevention of gay marriage and reproductive freedom, etc.
4. Church leaders are not trustworthy.

The third response supports the backlash hypothesis—that young people are leaving the Christian religion because they disagree with its conservative politics.

What can we conclude from all of this? Due to the positive association of religiosity with age, the percentage of nones is likely to continue to increase. This is good news for liberals. In an earlier post, I presented evidence suggesting that the most important causes of religiosity are poverty and lack of education. Barring an increase in the financial desperation of the middle class or a weakening of our system of public education—both very real possibilities—the future of organized religion does not seem very bright.
