Are People Flocking to Catholicism in the U.S.?

This post is a collaboration between CARA Senior Research Associate Mark M. Gray and Rubén Rodríguez Barrón, a Ph.D. student at the University of Chicago.   

Over the past year, anecdotes about a surge in conversions to Catholicism in the United States have been widespread. We've seen and heard of packed OCIA classes, record numbers at Easter Vigil, and especially large increases among young adults have fueled speculation that something significant is underway in 2025.

What does the data say? For now, the honest answer is: not much yet. 

Dioceses will not begin reporting their 2025 sacramental data until early 2026, and those figures will not be publicly available until the release of the 2026 Official Catholic Directory (OCD) later that summer or fall. Any claims about nationwide conversion trends in 2025 are therefore necessarily anecdotal.

That said, we can place those anecdotes in context by looking carefully at recent historical data (i.e., including all U.S. Latin Rite territorial arch/dioceses, the Personal Ordinariate of the Chair of St. Peter, and the Diocese of St. Thomas in the Virgin Islands). Using diocesan reports from OCD, we can examine how entries into the Catholic Church have changed over the past decade, how the COVID-19 pandemic disrupted those patterns, and where recent numbers appear to be exceeding prior expectations. We can also explore how much these trends vary across dioceses and how they differ when we focus specifically on adult entrants rather than total baptisms.

What follows does not answer whether 2025 represents a true turning point. But it does clarify what would count as evidence of one, and what the most recent data already suggest.

National Trends in Entries into the Church
In 2015, there were approximately 834,000 entries into the Catholic Church in the United States. These entries include infant baptisms, minor baptisms, adult baptisms, and receptions into full communion for those previously baptized in other Christian traditions.

From 2013 through 2019, total entries declined steadily, falling by roughly 30,000 per year on average. 

This downward trend was already well established before the COVID-19 pandemic began.
Then came the pandemic. Parish closures, delayed sacraments, and widespread disruption made normal participation difficult or impossible for extended periods of time. As a result, interpreting sacramental data during these years requires caution.

By 2022, total entries had returned to roughly the level one would expect if the pre-pandemic decline had continued uninterrupted. In 2023 and again in 2024, however, the number of entries rose above that projected trajectory.

Whether this represents the emergence of a new trend or simply a period of catch-up following pandemic disruptions remains unclear.

Where Are New Entrants Coming From?
Looking only at national totals can obscure important local variation. Unsurprisingly, archdioceses with the largest Catholic populations also tend to report the largest numbers of entrants. Population size matters.

That said, some dioceses stand out as clear outliers. Fresno and Miami, for example, rank far lower in total Catholic population than many other dioceses yet appear among the top ten in total entrants. Conversely, dioceses such as Phoenix and San Diego, which have very large Catholic populations, fall outside the top ten in raw entry counts.

These discrepancies suggest that population size alone does not fully explain where new entries are occurring.

Adjusting for Population Size
One way to account for population differences is to examine entries per 1,000 Catholics. This shifts attention away from sheer size and toward relative intensity.

Using this measure, the dioceses that rise to the top look very different. Smaller dioceses and specialized jurisdictions dominate the list, including the Personal Ordinariate of the Chair of St. Peter, which serves former Anglicans entering the Catholic Church.

It is important to note a limitation here. Catholic population figures reported in the OCD are estimates, and dioceses vary widely in how frequently and accurately they update them. Some dioceses report identical population figures year after year, while others make abrupt revisions. These inconsistencies can meaningfully affect per-capita calculations and should be kept in mind when interpreting rankings.

Focusing on Adult Entrants
Much of the recent anecdotal attention has focused specifically on adults entering the Church. Adult baptisms and receptions into full communion offer a narrower but more targeted lens on conversion. In raw numbers, large dioceses once again dominate.



However, when we adjust for population size, the pattern closely resembles what we saw for total entries per 1,000 Catholics.

The same dioceses tend to appear repeatedly, suggesting that places with high overall entry intensity also tend to see relatively strong adult participation.

Infant and Minor Baptisms Relative to Adult Entries

Another way to examine diocesan differences is to compare the number of infant and minor baptisms to the number of adult baptisms and receptions into full communion.

Nationally, dioceses average roughly six infant and minor baptisms for every one adult entry. Some dioceses fall well below that ratio, while others far exceed it.


Lower ratios indicate dioceses where adult entries make up a larger share of total sacramental life. Higher ratios often reflect demographic factors such as high birth rates rather than weak adult evangelization. Large arch/dioceses like Los Angeles and Fresno fall into this latter category and should not be interpreted negatively on this measure alone.

At the same time, arch/dioceses such as Wheeling-Charleston, Palm Beach, and Oklahoma City appear as notable outliers, combining relatively strong adult entry with substantial infant and minor baptisms. These cases merit closer attention.

Conclusion
So, are people flocking to Catholicism in the United States?

The available data do not yet allow us to answer that question definitively. What they do show is a more nuanced and interesting picture than either optimism or skepticism alone would suggest.

After years of steady decline prior to the pandemic, total entries into the Church returned to their expected trajectory by 2022 and then exceeded that trajectory in 2023 and 2024. Whether this reflects delayed participation during COVID or the beginning of a new pattern remains uncertain.

At the diocesan level, the story is uneven. Some dioceses appear to be experiencing something genuinely distinctive, while others look much as they have for years. Differences in population size, demographics, and institutional structure all shape what entry patterns look like on the ground.

When the 2025 data are finally released, they will matter not because they confirm a headline, but because they will tell us whether recent increases represent a short-term rebound or a more durable shift in how people are entering the Catholic Church in the United States.

For now, the prudent conclusion is simple: something may be happening, but the data are still catching up.

Where The Catholic Population Has Changed the Most

What part of the country has become more Catholic in the last 25 years? If one were to look at Catholic population growth it would be apparent that there are more Catholics in states where there are more people in 2025 than in 2000. Generally, when populations grow in the U.S., the number of Catholics grows. This can happen through natural increases (more births than deaths) as well as migration and immigration. Two states stand out here in recent years: Texas and Florida. On a regional level, the South has experienced a net gain of more than 7.4 million Catholics from 2000 to 2025. The West has seen minimal net growth adding 1 million Catholics. At the same time the Northeast lost 4.4 million Catholics and the Midwest lost 2.3 million in the last 25 years. This is all part of a broader long-term shift of the U.S. population from the “Rust Belt” of the Northeast and Midwest to the “Sun Belt” of the South and to a lesser extent the West.

The changes described above have occurred during an unusual period of decreasing mobility in the population. In 2006, the U.S. Census Bureau estimates that approximately 17% of the population moved during the year. This has steadily declined to an annual rate of about 12% in 2024.

There are a few “outliers” in the overall population change patterns described above when one is specifically looking at Catholics. First, it’s important to note that these estimations are based on the Association of Statisticians of American Religious Bodies (ASARB) decennial Religion Census, three Pew Research Center Religious Landscape Surveys, and the Comparative Study of Electoral System (CSES) surveys. Each of these collections has varying methods and limitations.

Reviewing what we can, it is apparent that states like Alaska and South Carolina stand out. In the 2000s, Alaska’s Catholic population was just over 50,000. Currently, Catholics number more than 110,000 in the state for a 111% increase over the last 25 years. Meanwhile, Alaska saw just 18% overall population growth during this period. South Carolina has shown incremental growth in its Catholic population over time. In 2000, just 3% of the state was Catholic and this more than doubled in the last 25 years. The Catholic population of South Carolina grew by more than 250% while the state overall experienced 37% population growth. In 2000, Catholics numbered about 136,000 in the state and now in 2025 represent more than 450,000. South Carolina is a Southern state. Thus, it is part of that shift to the Sun Belt. However, Catholics are growing in number here at a pace well above this general population shift.

There are other Southern states where we can see the Catholic population growth rate outpacing the total population growth rates. These include North Carolina, Georgia, Tennessee, and Alabama. Outside of this Southern shift there are a few other states where Catholic numbers are outpacing overall growth. Oklahoma has seen its Catholic population rise from just under 170,000 in 2000 to more than 350,000 in 2024 (growing by 80% compared to 23% for the total population). Nevada has seen its Catholic population rise from more than 330,000 in 2000 to approximately 695,000 in 2024 (growing by 107% compared to 64% for the total population).    

It’s important to note that states with rapid Catholic population growth are not the most Catholic in absolute numbers by any means. California remains the state with the largest number of Catholics followed by Texas, New York, and Florida. South Carolina sits in the middle of the pack of states in terms of its Catholic population size and Alaska is near the bottom.

Does AI Know Who the Pope Is?

We are undoubtedly in the feeding frenzy phase of artificial intelligence (AI) adoption. As of today, Sam Altman, the OpenAI chief has declared AI may be more intelligent than humans, noting "We are past the event horizon; the takeoff has started."

My response to Mr. Altman, to quote a line from Billy Madison (1995), "What you've just said is one of the most insanely idiotic things I have ever heard..." How could I (jokingly) say such a thing? AI is everywhere. Maybe even your toaster? There is a well understood pattern to technology adoption. When you were a kid you may have had a little red wagon called a "Radio Flyer." What did a wagon have to do with radio? Nothing. But the toy wagon was made during the early age of flight and radio and it was a popular thing to link it to these new technologies as a marketing ploy. In other words, if you think AI is everywhere now just wait until this Christmas gift buying season. Take Altman's declarations of crossing an "event horizon" cautiously as he continues to seek more investors.

Our executive director has told me people will ask him from time to time how CARA is using AI. I told him to let them know we are hesitant to do so because AI isn't Catholic. That's more than a joke. We specialize in doing research about and for the Church and in this way must speak intelligently about theology and Church history in the language specific to Catholicism. 

But AI knows everything right? Well does it actually "know" anything? Or is it just very fast at processing extremely large databases of information and past experience? I'll be honest no one really knows how AI works. But we can get a sense from interacting with it.

I asked ChatGPT to describe the recent conclave to me in the following way:


It's not that ChatGPT won't tell you who the current pope is if directly asked, "Who is the current pope?" You can see the response below: 

With one query Pope Leo XIV has never existed and in the next he does. Notice in the second ChatGPT is relying on searching the internet and returning information from the Vatican, Crux, ... and Wikipedia! Welcome to the "event horizon" of the age of internet regurgitation packaged in a narrative that sounds fairly human. Is that AI? Is it even intelligent? Is it any better than Google circa 2000? I know my answer, for now.

ChatGPT does have a recent events "blindspot." When its most recent training does not include current or even recent events it must use search just like the rest of us to look for information it doesn't have. But it can usually recover quickly. 

For example, on July 12, 2024 a video about "The Weirdest Hoax on the Internet" was released. This told the story of a student at the University of Surrey named Alan MacMasters who was cautioned by a professor about the quality of research sources. This inspired Alan and his friends, in 2013, to create a fake Wikipedia page claiming that a fictional man named Alan MacMasters invented the electric toaster in 1893. For many years this fake page made it into newspapers, local holidays honoring MacMasters, and even bread commercials. It became "real" history. When I asked ChatGPT who invented the electric toaster on July 12, 2024, the date of the video about the hoax was released, ChatGPT responded, Alan MacMasters. A day later, on July 13, 2024, it correctly returned the history of the development of the electric toaster without the fictional information.  

Yet, we are now more than a month past the conclave and ChatGPT cannot correctly explain the selection of Pope Leo XIV and instead claims he may be a fictional character. This is the technology corporations are relying on and human beings are losing their jobs to? Seriously?

I asked ChatGPT in June 2025 to "Please generate a painting of the current pope." It responded:

Here is the image that was created of the "current" pope:
 

How does CARA currently use AI? For now, you just read it. It's not ready or useful to us as a reliable and factual research resource (we're not alone). It may be in the future. I am confident of it. For now, its hype is bigger than its utility. Perhaps when we get to a point where we have future iterations of AI models running on quantum computers we will have something truly special as Altman is currently trying to sell (...or not).

We'll surely at least wait for ChatGPT to catch up with the rest of humanity and become fully aware of Pope Leo XIV's existence (...and maybe until it can beat an Atari 2600 at chess).  

...An update from July 10, 2025. I decided to upload a picture of Pope Leo XIV and ask GhatGPT to identify the person in the photo. I already knew it did not know of Pope Leo XIV but I thought it might be able to identify him as Bishop or Cardinal Prevost. What I got is below. It's comically bad...

...An update from August 7, 2025. ChatGPT has been updated. It's most recent training now includes information up to this month. So I checked again. Same routine. I asked how Pope Leo XIV was selected and got the same response indicating no awareness of the current pope. I then told the model to check again about the current pope using search (i.e., equivalent to any Google search you or I could do) and to ChatGPT's surprise Pope Leo XIV does exist! I then asked ChatGPT when it thought it would have an awareness of Pope Leo XIV without relying on search. Here is the response:
 

 
One would assume that training through August 2025 would include the events of May 2025. But then again we are dealing with the weird, wacky, and inaccurate reality of AI. It's a whole different realm!
