Sharp rise in religiously unaffiliated in the US

The Pew Research Center’s forum on Religion and Life today released its latest survey on the religious landscape in the US and they find that there are currently about 56 million religiously unaffiliated people in the US and they are the most rapidly growing group, jumping from 16.1% in 2007 to 22.8% in 2014. That is a huge increase. Non-Christian faiths showed a smaller increase over that same time period, from 4.7% to 5.9%. The big losers were Catholics (23.9% to 20.8%) and mainline Protestants (18.1% to 14.7%). Evangelicals have also dropped by about one percent.

There is an interesting feature about inter-religious marriages and its correlation with lack of religiosity.

Religious intermarriage also appears to be on the rise: Among Americans who have gotten married since 2010, nearly four-in-ten (39%) report that they are in religiously mixed marriages, compared with 19% among those who got married before 1960. The rise in intermarriage appears to be linked with the growth of the religiously unaffiliated population. Nearly one-in-five people surveyed who got married since 2010 are either religiously unaffiliated respondents who married a Christian spouse or Christians who married an unaffiliated spouse. By contrast, just 5% of people who got married before 1960 fit this profile.

There are also interesting data about age distribution. The unaffiliated are getting younger while Catholics and mainline Protestants are getting older.

PR_15.05.12_RLS-02While many U.S. religious groups are aging, the unaffiliated are comparatively young – and getting younger, on average, over time. As a rising cohort of highly unaffiliated Millennials reaches adulthood, the median age of unaffiliated adults has dropped to 36, down from 38 in 2007 and far lower than the general (adult) population’s median age of 46.4. By contrast, the median age of mainline Protestant adults in the new survey is 52 (up from 50 in 2007), and the median age of Catholic adults is 49 (up from 45 seven years earlier).

But this does not mean that the unaffiliated are growing simply because of generational displacement. The percentage of religiously unaffiliated is increasing across all age groups.

And the lesbian, gay, and bisexual community? They are by far the most unaffiliated.

Among respondents who identify themselves as gay, lesbian or bisexual, fully 41% are religiously unaffiliated, and fewer than half (48%) describe themselves as Christians. Non- Christian faiths also are represented in the gay community at higher rates than among the general public, with 11% of gay, lesbian and bisexual respondents identifying with faiths other than Christianity.

All this is bad news for religion in the US. You can be sure that this survey is going to lead to much discussion in the media because these Pew surveys are very comprehensive and an authoritative source on the state of religion, targeting more than 35,000 adults aged 18 and older. Already I heard a promo today on NPR’s The Diane Rhem Show saying that tomorrow they were going to discuss the causes and consequences of declining religious affiliation in the US.

    Yah!!! LOL. I cheered when I read this article last night.

    I’ve also done my part, being a lifelong xian who the fundies turned into a Militant Atheist.

    You can ground truth these reports. By checking your local areas and their churches.

    I get a local fundie xian churches newsletter every now and then. It’s free which is its one redeeming feaature.

    The local churches are losing members and money quite rapidly. To the point where they are laying off staff and deferring maintenance on their buildings. The largest xian bookstore in the USA also declared bankruptcy.

    The really odd thing about the locals. They have absolutely no idea why they are bleeding members and money!!!! None. (If they asked me, I would just tell them to look in the mirror and read Freethoughtblogs. They wouldn’t have the courage though.) This is a hazard of a reality free, thought free existence.

    The interesting part is how the ‘nones’ are both growing and becoming younger despite having lower birth rates. Young people are deconverting in large numbers.

  4. Chiroptera says

    The percentage of religiously unaffiliated is increasing across all age groups.

    I wonder how much of this is due to the crazy that is coming from so many of the leadership in the politically active, conservative denominations? I can see a lot of members in the pews being turned off by the clear lack of rationality and decency.

    If i weren’t for the ‘quiverful’ thing the evangelicals would also be dropping, 2 parents with 12 kids just to keep even.

    Unaffiliated does not necessarily equate to atheism or agnosticism. It does, however, equate to individuals thinking for themselves and not blindly following or allying themselves with religions. US believers have seen what religious leaders really stood for (e.g. war, theft, greed, child rape, selfishness, hypocrisy, etc.) and are turning their backs on them.

  7. anat says

    leftover1under, they split the ‘nones’ to atheists, agnostocs, unaffiliated who consider religion unimportant and those who consider it important. Atheists and agnostics are on the increase, and within the unaffiliated the greater increase is among those who consider religion unimportant.

    Perhaps “unaffiliated” is a stage in the process of shedding belief. Regardless, getting away from religious authority is good in and of itself. And exploring non-Western faiths shows a willingness to not conform to the dominant religions.
