10 Reasons Why Christianity is Declining—and Atheism is Growing

I'm Nevets: Nerd, cinephile, TV-junkie, bookworm, gamer, and slacker extraordinaire.

The results are in!

Good news, heathens! According to a recently released study by the Pew Research Center, it looks like America is becoming less and less of a Christian nation with each passing day. More surprising? The religiously unaffiliated is growing in a big, bad way.

The study (available here) found that the number of religiously unaffiliated Americans has skyrocketed from a mere 16.1% to 22.8% of the population. This number consists of a combination in the rise of atheism, agnosticism, and "nothing in particulars". This now makes the non-religious (none's) the second largest "religion" in the nation.

Christianity, of course, still rules the roost with a staggering 70.6% of the population on their team. But as large as this number is, it's one that's rapidly declining with each passing year. In just seven years (since the last massive Pew study) the number of American Christians has dropped nearly 8 percentage points from its previous 78.4%. This is a mighty steep decline for such short period of time, and the question remains: Why is it happening?

While there is no one particular answer as to why Christian numbers are declining and the numbers of atheists, agnostics, and "nones", in general, are rising, there are several possible (and probable) reasons for the change. This is the topic we're going to explore today with the following 10 possible reasons why Christianity is losing its grip on Americans.

It's true! Just take a look at your Facebook feed; chances are you won't have to scroll down too far before you find that someone has either shared or "Like'd" something science related. Even astrophysicist Neil deGrasse Tyson's very image (accompanied by a "Badass over here" text) has become an inescapable internet meme. Pretty cool-weird, huh? This is just a small example of how science's popularity is spreading in our culture. A culture that's suddenly seeing science as a fun, interesting, and valid, non-magical source for answers that we couldn't find anywhere else.

Speaking of Tyson, his reboot of The Cosmos recently became a hit documentary series on 10 different television networks, and his podcast, Startalk, was ranked number 13 on Rolling Stone Magazine's "Top 20 Best Comedy Podcasts Right Now" (and it's since even become a TV talk show!). Couple this bizarreness with the knowledge that the top ranking sitcom over the last several years has been one about a group of nerdy physicists and engineers (CBS's The Big Bang Theory), and the fact that movies about Stephen Hawking, mathematician Alan Turing, and even one about time dilation and black holes have each won Academy Awards in 2015, it shouldn't take long before the evidence adds up — science has finally begun to get its time in the limelight.

How this has to do with the decline of Christianity and the rise of atheism could simply have to do with the fact that science itself is devoid of religious ideas, and that it so often directly contradicts specifics of religious beliefs. Christian views having to do with spontaneous creation, a 6,000 year-old earth, virgin births, Noah's flood, miracles, resurrections, and so forth, are all impossibilities and improbabilities in the scientific point of view. And when we adopt and accept that point of view, we're left disposing of those less-worldly explanations. This may not always cause someone to let go of their religion, of course, but it may act as a very real starting point, where letting go of the magical tales and the need to use religion as an explanation, is only the beginning.

As scientific knowledge grows, it's always had the tendency of wedging religion out of the way (just look at the amount of non-believers who are scientists). With scientific awareness now becoming widespread among the general public, this effect may be occurring in a lot more lives.

9.) Famous non-believers have come out of the closet,_2006.jpg,_2006.jpg

Like it or not, we're living in a world where the rich and famous are idolized, respected, and adored. This includes not just movie stars and musicians, but politicians, news commentators, comedians, science popularizers, authors, and pretty much anyone else under the sun who happens to be in the public eye. And with Twitter, Facebook, gossip blogs, the paparazzi, and even news channels getting into the mix (hooking us up with an onslaught of daily access to celebrities personal lives) we now know everything about these famous figures — Including their religions.

You only need look at peoples fashions to know how highly influenced we are by famous figures whom we admire and/or respect. Being influenced by their religion (or lack thereof) isn't too different. When someone sees Brad Pitt on TV, for instance, telling us that he's an atheist-agnostic, it wouldn't be unusual for them to think "Hey, I always thought atheists were bad. But if Brad Pitt is one, then maybe there's something to it. I always liked him." Similarly, if someone is already having atheistic thoughts, maybe hearing that a celebrity they enjoy is an atheist could be enough to let them know it's okay for them to be one too.

Not too different from how Will & Grace made it okay for more gays to come out of the closet, sometimes non-believers just need to know they're not alone (and not weirdo's) before they can muster up the courage to tell the world how they feel.

8.) Film, TV, and the media


Not unlike the influence of celebrity, film, television, and other forms of media can also be highly persuasive in determining our opinions on religion. When shows like South Park or Family Guy, for instance, poke fun at religion, ridicule faith, or make a joke out of Jesus, that can have a huge impact on a viewers religious perspective (especially a young one). Because, while the jokes are only jokes, they can also convey an irreverent opinion, point out flaws otherwise unnoticed, and can result in the viewer henceforth associating the mocked beliefs with silliness and absurdity.

To understand this from an outside point of view, think about Scientology — a comparatively new religion — and how often we've heard it joked about on movies and TV, and the mouths of comedians. For a lot of us, the first we were introduced to that religion was from hearing it being made fun of. Due to this, most couldn't disassociate Scientology from wackiness and ridiculousness if we tried. It's, thankfully, ruined for us. If we were to primarily hear Christianity spoken about in a mocking or irreverent sense, then perhaps we'd disassociate ourselves from that as well. After all, no one wants to be the butt of the joke.

It's not just how media mocks or makes fun of religion that turns us off to it, of course. We're also now exposed to more open debates and conversations having to do with those beliefs and their proposed fallacies. On popular TV shows such as Real Time with Bill Maher, for example, we often find theists and atheists getting into deep discussions (sometimes even arguments) over the topic. On shows such as Penn & Teller's Bullsh!t, we were shown sociological experiments disproving supernatural events, and the promotion of a more scientific outlook on supposedly miraculous events. On science documentaries we're repeatedly presented with a stream of scientific theories and explanations about the universe that run contrary to what our religions would have us believe. This list goes on and on and has even carried on to films (see The Atheist Friendly Movies List, for more on those).

Combined, all of these movies, TV shows, news programs, and stand-up comedians have an impact on us as viewers. More so for younger viewers, for sure, but an influence on all of us nevertheless. They have the ability to open us up to new ideas, they give in-the-closet non-believers the extra nudge they need to come out, and, most of all, they cause us to think more deeply about the topic of religion when they openly question it in their respective popular mediums.

7.) Non-belief is in style and reaching a critical mass

As with the spread of African American culture, the almost unanimous acceptance of homosexuals and diverse races in society, and even the strange growth in the popularity of comic book heroes (seriously, there was actually a time when it was just "nerds" who liked that stuff), the counterculture grows into the cultural norm all the time. All it takes is a group of supporters, proponents, fans, activists, a good idea, a new innovation ect., to set the ball in motion, expose us to their influence, and finally for the trend to catch on and eventually take over. This is called reaching a critical mass. And it's occurring with non-belief.

People have been becoming less religious for decades, but today it's happening quicker than ever. This may be due to the introduction of the internet and other social media in our world and how it's helping spread ideas at a much faster rate. Now, an inevitable critical mass (which could typically take decades or even millenniums to occur) can be achieved quicker than ever before.

6.) America's changing political climate & religions bad image


We're in an atmosphere of big changes here in America, especially when it comes to such issues as the rights for gays to marry — something which we never would have thought possible just a mere 10 years ago, but is now quickly becoming a reality all over the country and the world. Not too different from the subtle acceptance grown of blacks during the late 19th century through to the 1960's, progressiveness is occurring. Those not on board are quickly being left behind, and American's are steadily beginning to disassociate themselves from those dissenters; who, typically, consist of a lot of Christians.

When we see the Tea Party and the others from the religious right begin fighting so vehemently against these issues, it doesn't bode well for their image in this growingly progressive public eye — or, subsequently, the image of the religion which motivates them. In essence, they're becoming a large contributor to what's giving Christianity such a bad wrap.

Due to the emergence of this vocal and highly-visible sect of the religious right, we're all forced to focus more on issues such as homosexuality and evolution, and the religion that's against them. Whether liberal or conservative, the god issue is now a relevant topic in politics. People who normally never gave their Christianity a second thought are now made to face it, and either defend or question the beliefs that come with it. And the youth of the nation is growing up not seeing the religion as one of love; but one of hate, ignorance and bigotry.

5.) The Internet — Irreligion goes viral

How the internet may have affected religious affiliation could have to do with two long-known facts:

  1. The biggest influence to an individuals personal religion is that of their home life and immediate environment.
  2. Studies have repeatedly shown correlations between the rise in education leading to a decrease in religious affiliation.

Since the rise of the internet, the following has occurred:

  1. People (now beginning at young ages) are no longer restricted to discussing topics with only their friends, family, teachers, acquaintances, and coworkers. They now have access to communicate with different kinds of people with varying ideas, knowledge, and beliefs, from all over the world.
  2. Intelligence has risen. Likely helped by the internet's open access to every opinion, idea, study, statistic, scientific discovery, and answer to almost any question we can muster.

Before the internet, the only access we had to the outside world was from our televisions, radios, libraries, and newspapers; with our only personal influences being those around us. With all of the information, opinions, and knowledge of the world now at our fingertips and literally in our pockets, our lives and beliefs were bound to be impacted.

It's not only that information is available to us, though. We're also generally exposed to more than just the opinions of whatever circle we chose to affiliate ourselves with. Just one look at the comments section of any religious or atheist website, article, or video will clearly show how impossible it is to ignore dissenting opinions these days. No longer are the days when we could simply insulate ourselves from outside views. Which brings us to our next reason for the drop in religious beliefs...

4.) We're now forced to talk about and question religion

Bill Nye vs Ken Ham debate was held at the Creation Museum's 900-seat Legacy Hall and sold out within minutes. Approximately 750,000 computers logged into the live stream.  It's estimated that almost 3 million people viewed the event live online.

Bill Nye vs Ken Ham debate was held at the Creation Museum's 900-seat Legacy Hall and sold out within minutes. Approximately 750,000 computers logged into the live stream. It's estimated that almost 3 million people viewed the event live online.

The topic of religion and belief has become unavoidable in today's culture and society. As mentioned above, it's now a relevant talking point in politics, its debated on all over the internet (veritably anywhere religion is even slightly mentioned), and it's regularly becoming comedy fodder in film, TV, and stand-up comedy. And with the rise of vocal secularist groups and such high-profile atheists as Richard Dawkins, Christopher Hitchens, Sam Harris, and Lawrence Krauss, religion is also now being specifically called out on its shenanigans on a regular basis.

Due to this, religious groups which hold firm in their beliefs are being put in the spotlight, and have become even more vocal in their views, in order to defend them. The results include incidences such as the one pictured above, where biblical creationist Ken Ham and popular scientist Bill Nye (the science guy) were put head to head in a sold-out debate concerning the origins of the human race. A debate watched live on approximately 750,000 computer screens by about 3 million people — pretty amazing numbers for a science debate.

Things have made it to a point where we're all forced into the position of picking sides. No longer are the days when we can simply accept our religions without questions, or easily isolate ourselves from the voices of dissenting opinions. And while this may strengthen many believers into more strongly defending their faith, for some, the dissenters are making sense, and the "converts" — who were otherwise unaccustomed to seeing alternative views — are growing.

3.) People are getting smarter

IQ scores have been increasing steadily since the beginning of the 20th century. This is a fact that was first discovered by a researcher at the University of Otago in New Zealan, named James R. Flynn, over twenty-eight years ago. It's now called The Flynn Effect, and it's a phenomena that's still occurring to this day. The bottom line to this is that we're getting smarter. Our health is improving, our schools are improving, and, thanks to the internet, our easy access to knowledge and new ideas has become almost limitless — all contributing factors to intelligence.

It's also been found in numerous studies (dating as far back as the 1920's) that there is a direct correlation between the rise in intelligence and education with a drop in religiosity. Meaning it's highly possible that the reason for the steady decline of Christianity in America may be due to the increased knowledge and education in the American people.

2.) A new generation is taking control

Taken from The Pew Research Center:

One of the most important factors in the declining share of Christians and the growth of the “nones” is generational replacement. As the Millennial generation enters adulthood, its members display much lower levels of religious affiliation, including less connection with Christian churches, than older generations. Fully 36% of young Millennials (those between the ages of 18 and 24) are religiously unaffiliated, as are 34% of older Millennials (ages 25-33). And fewer than six-in-ten Millennials identify with any branch of Christianity, compared with seven-in-ten or more among older generations, including Baby Boomers and Gen-Xers. Just 16% of Millennials are Catholic, and only 11% identify with mainline Protestantism. Roughly one-in-five are evangelical Protestants.

While it's true that rise in the "none's" is appearing in all ages, the unavoidable conclusion here is that, regardless of the reasons, the newest generation of adults is composed of one heck of a lot of non-believers. And these numbers are rising steadily, showing no signs of slowing down. The results being, as the older generation dies out, the most religious of our nation goes right along with them.

1.) Everything combined

In the end, the answer as to why Christianity in America is dwindling and the non-religious is growing is more than likely a combination of everything mentioned above; and then some. Together, they all culminate into a perfect storm of reasons to say goodbye to our previously held beliefs.

With the decline in the literal interpretation of scripture causing religion to lose it relevance; our rise in scientific awareness; the less-religious youth growing up; our easy exposure to new and diverse beliefs and opinions; and our continuous bombardment of the negative aspects, affects, bigotry, and fallacies of religions, every day we're being given more and more reasons to drop our religious ideas.

Whether this trend will last, no one knows. But, at least for the moment, we're seeing no sign of it slowing down.

CH Elijah Sadaphal from New York, NY on August 17, 2016:

Your hub has pointed out some very plausible explanations to describe an American phenomenon. Interestingly however, the paradigm that applies in America and the West (generally speaking) does not apply to the global population: that is, in a separate study, the same group (Pew) projected (1) that by the year 2070, Islam will be the world's majority religion and (2) while the unaffiliated compose 16.4% of the share of the global population now, that share is projected to be 13.2% in 2050.

Though atheism might be on the rise in West. I am pretty sure Muslim Countries are going to adhere to their religion. :)

Hey, Paul! Thanks for the comment, share, and kind words. You're aces! Let's hope the trend continues. (Of the critical thinking, I mean...)

@ Colin323

Hi, Colin. Personally, I've always been a bit wary about using the word "spiritual", as it's always appeared a vague and oftentimes misleading term that could easily be tossed around to mean almost anything involving deep feelings. Strictly speaking, there is no agreed upon definition for it, so I'm not sure if it would have much relevance for a survey about religion.

With that being said, I do agree that many people do have that vague wonder, hope, love, admiration, and feeling of awe in the face of nature, family, friends, the universe and the unexplained. The religious may call it "spiritual" in reference to an actual soul or the supernatural, and the non-religious may refer to it as "spiritual" in a more-or-less poetic figure of speech. The difficulty it seems, in my perspective, is deciphering who's meaning what when the term is used.

Personally, I chose the latter meaning. And under the latters interpretation of the word "spiritual" I can sympathize wholly (even if I wouldn't use that particular phrase to describe the feeling). People often seem to make a connection between a lack of god and religion with a lack of hope and happiness. But those people don't seem to realize that hope and happiness comes in many different forms for many different people. For many of us, nature and the universe is all we need.

But anyways! I've blathered on enough. Thanks for your comment! I hope you enjoyed the read.

Colin323 on June 01, 2015:

Ask people a different question - about their sense of spirituality, rather than about affiliation to an organised religion, and I suspect you would get a different picture. As your interesting article suggests, people are less inclined these days to affiliate to a particular Christian religion. But many people, I would argue, still have a profound sense of spirituality that may express itself in ways not associated with organised worship of a deity: a love of animals; of nature; of family; of others in the community, expressed in many and various life-affirming ways. Replace 'doing Good' for 'doing God' and you will have a more complete social picture these days.

The Gutter Monkey (author) on June 01, 2015:

Hey Kylyssa! Thanks for the kind words. And I agree, the internet does seem to be the most plausible / dominant explanation for the rise — Where once we were all restricted to just the views of our environment, we now have easy access to everyone and everything at any moment. It would be amazing if such a change didn't have a large impact on our society.

Anywho, thanks again!

Kylyssa Shay from Overlooking a meadow near Grand Rapids, Michigan, USA on June 01, 2015:

Those all look like plausible reasons to me. I think the Internet is the biggest player. It's harder to isolate people from information now.

Well-worded and worth sharing.
