Gen Z and Religion in 2021

by Ryan P. Burge, Eastern Illinois University

Looking for an updated version of this post? Gen Z and Religion in 2022.

It’s been nearly two years since I’ve written a post about the precarious religious position of Generation Z (those born after 1995), and with data from late 2021 available it seems like a prime opportunity to update what we know about their religious inclinations. Because almost all surveys only contact adult Americans (18+), we can’t get a full picture of the entirety of Gen Z, but just the oldest members of this generation. Thus, here I am analyzing those between the ages of 18 and 25 years old. 

Let’s start broadly, comparing the religious composition of different generations beginning with the Silent Generation (who were born between 1925 and 1945). In this generation, half of all respondents indicated that they were Protestant, while 22% said that they were Catholic. Just eight percent of the Silent Generation say that they were atheists or agnostics and nearly the same share describe their religion as “nothing in particular” (10%). In sum, the oldest Americans are 72% Christian and 18% none. 

Now, for Generation Z things are much different. Just twenty-two percent of the youngest adults describe themselves as Protestant  –  a more than fifty percent decline from the Silents. Catholics make up fourteen percent of Gen Z, an eight percentage point dip from the Silent Generation. Of course, the share of nones is much larger. Seventeen percent of young people describe their religion as atheist or agnostic, and thirty-one percent say that they are attached to no religion in particular. Taken together, 36% of Gen Z are Christians, while 48% are nones. They are the first generation in history in which the nones clearly outnumber the Christians. 

Is the rise of the nones accelerating equally among all generational cohorts or is it just happening among the youngest Americans? The answer is a bit nuanced. The graph above visualizes the share who were nones in 2008, 2012, 2016, 2020 and 2021 for each of the five generations mentioned previously. 

While just twelve percent of Silents were nones in 2008, that has risen fifty percent to 18% today. For Boomers, the increase was from 17% to 26%. Generation X has jumped from a quarter nones in 2008 to thirty-six percent in 2021. It’s worth pointing out that there’s a larger share of Gen X nones in 2021 than there were of Millennial nones in 2008. But for each of these three previously mentioned generations, there’s been a steady increase, although that increase seems to have slowed significantly between 2016 and 2021. 

For Millennials, that’s not the case. One third of them were nones in 2008. That jumped four percentage points by 2012, but only inched up a single point to 38% between 2012 and 2016. However, from that point forward Millennials have left behind religious affiliation in droves  –  seeing a seven point increase in just five years. 

That same general trend is evident among members of Generation Z. The earliest they showed up in polls was in 2016, when thirty-nine percent were nones. That rose six percentage points by 2020, then crept up another three points just between 2020 and 2021. Now, nearly half of Gen Z says that they have no religious affiliation. 

However, there’s also a finding in the data that seems to run counter to the trend previously described. When looking at each generation through the lens of religious service attendance, it would be reasonable to assume that younger generations are less likely to attend services than older Americans. But, that’s not exactly the case. 

When it comes to which generation is the most absent from worship it’s not Generation Z, it’s the Millennials and Gen X. Sixty percent of Millennials say that they attend services seldom or never, which is statistically the same as Generation X. Compared to those two generations, Gen Z is slightly more likely to attend worship. Thirty-six percent said that they never attended and another eighteen percent indicated that their attendance was seldom. That’s only 54%  –  about six percentage points lower than the two prior generations. At the same time, twenty three percent of Gen Z are weekly attenders, which is higher than Gen X or Millennials (21%). 

It’s not easy to figure out why there’s this noticeable uptick in attendance among Generation Z. In data from Dan Cox at the American Enterprise Institute, he reports that 47% of Gen Z never attend services, that’s eleven points higher than in the CES. And, when I checked the same figures with the General Social Survey, it was 41% who never attended. So, this may be just a statistical aberration in his data. 

Regardless, we have a picture of a rapidly secularizing America that will significantly alter the culture and politics of the United States for generations to come. A majority of Baby Boomers are now in their retirement years, and even the youngest Boomers will exit the workforce in the next few years. That leaves Gen X (35% Nones; 60% never/seldom attend) and Millennials (45% Nones; 60% never/seldom attend) to take over the institutions that give structure and order to American life. We have only begun to consider just how seismic this shift will be.

  1. Those are sobering, alarming statistics. Do we know why things are happening that way? Do we know what is driving the youngest generations away from faith? I am at the younger end if the Baby Boom and cannot imagine life without it.


    • My perspective or opinion is the opposite of yours. I’m a GenX’er who was in consecrated Catholic religious life back in the 90s. Now I’m somewhere in the agnostic-atheist spectrum, and my GenZ kids are in the Nones camp – well, my daughter has been looking at Zen Buddhism, so maybe she’s an “Other”, I’m not sure. Not that this will assuage your fears at all, but I can assure you that I am every bit as good a person now as a was in with faith; maybe better, because I’m more honest with myself. And my kids are alright too.


  2. Do we have any detail on whether or not the pandemic had effects on religious identification or attendance? It’s plausible, but hard to discern.


  3. I teach Intro Philosophy at a community college and when I ask my students to write about a 180 degree change in their thinking about one in five mention leaving their (mostly Christian) faith mostly because of the hypocrisy and irrationality (anti-science, etc.) they observed among believers.


  4. Don’t you think that lack of religious affiliation has nothing to do with spirituality? I mean I taught students for 36 years and I noticed less and less of them referred to themselves as catholic or something else but more and more believed in the spirituality of things.
