Church charity statistics at a glance
Church charity statistics are easiest to read when you look at the scale of congregations and adherents side by side. The dataset below shows how much organizational footprint can sit behind a church tradition, and how quickly that footprint changes when you compare one denomination with another.
At-a-glance takeaways
- The Catholic Church is the largest entry in the dataset, with 19,405 congregations and 61,858,137 adherents, plus an adherence rate of 186.63 (ARDA U.S. Membership Report 2020).
- Non-denominational Christian Churches appear with 44,319 congregations and 21,095,641 adherents, which makes them one of the widest congregation networks in the list (ARDA U.S. Membership Report 2020).
- The Southern Baptist Convention reports 51,379 congregations, the highest congregation count in this dataset, and 17,649,040 adherents (ARDA U.S. Membership Report 2020).
- Several traditions have large congregational networks but much smaller adherence totals, which is a reminder that church charity statistics measure structure and membership differently (ARDA U.S. Membership Report 2020).

How to read these church charity statistics
The dataset is not a donation ledger or a direct measure of charity spending. It is a membership-and-congregation snapshot drawn from the ARDA U.S. Membership Report 2020, so the most reliable way to use it is to compare scale, density, and organizational reach.
The three numbers repeated across the rows are the core of the story. Congregations show how spread out a tradition is. Adherents show how many people are counted in the tradition. Adherence rate gives another way to compare presence, because it puts the tradition on a common scale rather than only counting raw totals (ARDA U.S. Membership Report 2020).
The core dataset fields
- Congregations: the number of individual congregational units reported.
- Adherents: the total adherent count reported.
- Adherence rate: the comparative rate shown in the source row.
A useful way to think about the dataset is this: large congregational footprint does not always mean the largest adherent base, and a very large adherent total can coexist with a smaller number of congregations. That tension shows up repeatedly in the table below.
The largest traditions by adherents
If you sort the list by adherents, the top of the field is dominated by a few very large traditions. The Catholic Church leads by a wide margin with 61,858,137 adherents and 19,405 congregations (ARDA U.S. Membership Report 2020). That single row is a useful anchor for the entire dataset because it sets the upper end of the adherence scale.
Right behind it, Non-denominational Christian Churches report 21,095,641 adherents across 44,319 congregations, and the Southern Baptist Convention reports 17,649,040 adherents across 51,379 congregations (ARDA U.S. Membership Report 2020). Those two rows are especially important because they show different forms of scale. One is defined by very broad congregational spread, while the other combines broad spread with a very large adherent total.
Top adherent totals
| Tradition | Congregations | Adherents | Adherence rate |
|---|---|---|---|
| Catholic Church | 19,405 | 61,858,137 | 186.63 |
| Non-denominational Christian Churches | 44,319 | 21,095,641 | 63.65 |
| Southern Baptist Convention | 51,379 | 17,649,040 | 53.25 |
| United Methodist Church | 30,051 | 8,018,629 | 24.19 |
| Church of Jesus Christ of Latter-day Saints | 14,567 | 6,721,031 | 20.28 |
| Muslim Estimate | 2,771 | 4,453,908 | 13.44 |
| Evangelical Lutheran Church in America | 8,857 | 3,139,413 | 9.47 |
| Assemblies of God, General Council of the | 12,739 | 3,094,547 | 9.34 |
| Jehovah’s Witnesses | 12,285 | 3,016,924 | 9.10 |
| National Missionary Baptist Convention of America | 7,564 | 2,428,820 | 7.33 |
The first ten rows already show a wide range of institutional shapes. For example, the United Methodist Church reports 30,051 congregations and 8,018,629 adherents, while the Church of Jesus Christ of Latter-day Saints reports 14,567 congregations and 6,721,031 adherents (ARDA U.S. Membership Report 2020). Both are large by any measure, but they do not scale in the same way.
A few immediate comparisons
- The Catholic Church has about three times the adherents of the Southern Baptist Convention, but fewer congregations than the Southern Baptist Convention (ARDA U.S. Membership Report 2020).
- Non-denominational Christian Churches have fewer adherents than the Catholic Church, but nearly as many congregations as some much larger traditions combined across the rest of the list (ARDA U.S. Membership Report 2020).
- The Muslim Estimate row has 4,453,908 adherents but only 2,771 congregations, showing a very different congregational profile than the Christian traditions above it (ARDA U.S. Membership Report 2020).
The largest traditions by congregations
Counting congregations alone changes the picture. The Southern Baptist Convention leads the dataset with 51,379 congregations, followed closely by Non-denominational Christian Churches with 44,319 congregations (ARDA U.S. Membership Report 2020). After that, the United Methodist Church reports 30,051 congregations, then the Catholic Church with 19,405 congregations, and the Church of Jesus Christ of Latter-day Saints with 14,567 congregations (ARDA U.S. Membership Report 2020).
That ordering matters because it shows the difference between reach and membership density. A tradition can be highly distributed without being the largest by adherents. It can also have a very large adherent base with comparatively fewer congregational units.
Top congregation totals
| Tradition | Congregations | Adherents | Adherence rate |
|---|---|---|---|
| Southern Baptist Convention | 51,379 | 17,649,040 | 53.25 |
| Non-denominational Christian Churches | 44,319 | 21,095,641 | 63.65 |
| United Methodist Church | 30,051 | 8,018,629 | 24.19 |
| Catholic Church | 19,405 | 61,858,137 | 186.63 |
| Church of Jesus Christ of Latter-day Saints | 14,567 | 6,721,031 | 20.28 |
| Assemblies of God, General Council of the | 12,739 | 3,094,547 | 9.34 |
| Jehovah’s Witnesses | 12,285 | 3,016,924 | 9.10 |
| Churches of Christ | 11,881 | 1,422,331 | 4.29 |
| Evangelical Lutheran Church in America | 8,857 | 3,139,413 | 9.47 |
| Presbyterian Church (U.S.A.) | 8,851 | 1,491,775 | 4.50 |
The congregation table makes one thing clear: some of the largest church networks are not the largest membership pools. For example, Churches of Christ report 11,881 congregations and 1,422,331 adherents, while the Presbyterian Church (U.S.A.) reports 8,851 congregations and 1,491,775 adherents (ARDA U.S. Membership Report 2020). That is a useful comparison because the two rows are similar in congregation count but not identical in adherent total.
What these top rows suggest
- Congregational spread is not a direct substitute for adherent count.
- Large traditions can be “wide” in geography and still vary a lot in membership totals.
- The dataset rewards reading both columns together rather than focusing on just one.
What adherence rate adds to the picture
The adherence rate column gives the dataset another layer of comparison. The Catholic Church’s 186.63 stands far above every other row in the list, and that alone signals that it is not just large, but outsized relative to the rest of the field in this source (ARDA U.S. Membership Report 2020).
The next highest rates in the top tier are 63.65 for Non-denominational Christian Churches and 53.25 for the Southern Baptist Convention, followed by 24.19 for the United Methodist Church and 20.28 for the Church of Jesus Christ of Latter-day Saints (ARDA U.S. Membership Report 2020).
That spread matters because adherence rate helps separate the biggest absolute counts from the most concentrated presence. It is a cleaner comparison than congregation count alone when you want to understand how dominant a tradition is within the source framing.
Highest adherence rates in the dataset
| Tradition | Congregations | Adherents | Adherence rate |
|---|---|---|---|
| Catholic Church | 19,405 | 61,858,137 | 186.63 |
| Non-denominational Christian Churches | 44,319 | 21,095,641 | 63.65 |
| Southern Baptist Convention | 51,379 | 17,649,040 | 53.25 |
| United Methodist Church | 30,051 | 8,018,629 | 24.19 |
| Church of Jesus Christ of Latter-day Saints | 14,567 | 6,721,031 | 20.28 |
| Muslim Estimate | 2,771 | 4,453,908 | 13.44 |
| Evangelical Lutheran Church in America | 8,857 | 3,139,413 | 9.47 |
| Assemblies of God, General Council of the | 12,739 | 3,094,547 | 9.34 |
| Jehovah’s Witnesses | 12,285 | 3,016,924 | 9.10 |
| National Missionary Baptist Convention of America | 7,564 | 2,428,820 | 7.33 |
The middle of the table drops sharply after those first few rows. That gap tells you that the dataset is heavily concentrated at the top and then spreads into a long tail of smaller traditions.
Mid-sized traditions and close comparisons
The middle rows are where the comparison work gets interesting, because many traditions cluster tightly enough that the numbers invite direct side-by-side reading.
The Lutheran Church-Missouri Synod reports 5,897 congregations and 1,802,680 adherents. The Episcopal Church reports 6,353 congregations and 1,576,611 adherents. The National Baptist Convention, USA, Inc. reports 2,530 congregations and 1,567,741 adherents (ARDA U.S. Membership Report 2020). Those three rows show how differently similar-sized traditions can present across the two main measures.
Another close grouping appears with the Presbyterian Church (U.S.A.), Churches of Christ, Christian Churches and Churches of Christ, and the Seventh-day Adventist Church. Their congregation totals range from 3,135 to 11,881, while their adherent totals range from 1,339,830 to 1,491,775 in the source rows (ARDA U.S. Membership Report 2020).
Mid-tier comparison table
| Tradition | Congregations | Adherents | Adherence rate |
|---|---|---|---|
| Lutheran Church-Missouri Synod (LCMS) | 5,897 | 1,802,680 | 5.44 |
| Episcopal Church | 6,353 | 1,576,611 | 4.76 |
| National Baptist Convention, USA, Inc. | 2,530 | 1,567,741 | 4.73 |
| Presbyterian Church (U.S.A.) | 8,851 | 1,491,775 | 4.50 |
| Churches of Christ | 11,881 | 1,422,331 | 4.29 |
| Christian Churches and Churches of Christ | 4,787 | 1,379,041 | 4.16 |
| Seventh-day Adventist Church | 5,989 | 1,339,830 | 4.04 |
| American Baptist Churches in the U.S.A. | 4,790 | 1,259,804 | 3.80 |
| African Methodist Episcopal Church | 3,667 | 1,059,888 | 3.20 |
| Orthodox Judaism | 914 | 941,480 | 2.84 |
Two rows stand out in particular. Orthodox Judaism reports only 914 congregations but 941,480 adherents, which makes it one of the more concentrated entries in the dataset. By contrast, Churches of Christ reports 11,881 congregations and 1,422,331 adherents, so it is much broader organizationally but not proportionally larger in adherents (ARDA U.S. Membership Report 2020).
Smaller traditions that still matter in the dataset
The bottom half of the list is not filler. It shows traditions that may be smaller by congregation count or adherence count, but still register clearly in the national picture. That makes the data more useful than a simple top-ten list, because it captures the long tail.
Examples include the United Church of Christ with 4,793 congregations and 924,744 adherents, the Church of God in Christ with 3,313 congregations and 920,429 adherents, and the Church of the Nazarene with 5,155 congregations and 905,690 adherents (ARDA U.S. Membership Report 2020).
The list also includes several traditions with fewer than 1,000 congregations but still meaningful adherent totals. Reform Judaism reports 690 congregations and 662,104 adherents. Conservative Judaism reports 529 congregations and 417,316 adherents. Greek Orthodox Archdiocese of America reports 533 congregations and 375,117 adherents (ARDA U.S. Membership Report 2020).
Selected smaller entries
- United Church of Christ: 4,793 congregations, 924,744 adherents, adherence rate 2.79 (ARDA U.S. Membership Report 2020).
- Church of God in Christ: 3,313 congregations, 920,429 adherents, adherence rate 2.78 (ARDA U.S. Membership Report 2020).
- Church of the Nazarene: 5,155 congregations, 905,690 adherents, adherence rate 2.73 (ARDA U.S. Membership Report 2020).
- Reform Judaism: 690 congregations, 662,104 adherents, adherence rate 2.00 (ARDA U.S. Membership Report 2020).
- Greek Orthodox Archdiocese of America: 533 congregations, 375,117 adherents, adherence rate 1.13 (ARDA U.S. Membership Report 2020).
These rows show that lower congregation counts do not automatically mean low adherent totals. In some cases, a tradition may be comparatively concentrated but still represent hundreds of thousands of adherents in the dataset.
Patterns the data makes visible
Several patterns repeat across the source rows.
1. Congregation count and adherent count are related, but not interchangeable
The Southern Baptist Convention has the most congregations, while the Catholic Church has the most adherents. That alone shows the limits of reading only one column. A church charity statistics article should keep both in view, because the institution’s footprint and its member base can move in different directions (ARDA U.S. Membership Report 2020).
2. The top of the dataset is unusually concentrated
The first few rows account for very large shares of the visible totals. Catholic Church, Non-denominational Christian Churches, and Southern Baptist Convention all sit far above the mid-tier in adherents, while a smaller cluster of traditions follows with totals in the single-digit millions or low millions (ARDA U.S. Membership Report 2020).
3. Some traditions are congregation-heavy without being adherence-heavy
This is especially visible in the Southern Baptist Convention, Non-denominational Christian Churches, Churches of Christ, and Presbyterian Church (U.S.A.) rows. These traditions show that dense networks of congregations can support relatively modest adherent totals compared with the very top of the list (ARDA U.S. Membership Report 2020).
4. Smaller traditions can still be numerically significant
Rows such as Orthodox Judaism, Reform Judaism, Conservative Judaism, and Greek Orthodox Archdiocese of America show that smaller congregation counts can still accompany large adherent bases. That long-tail structure is one of the most useful takeaways from the dataset (ARDA U.S. Membership Report 2020).
5. The dataset is better for comparison than for single-number claims
If you only quote the largest adherent count, you miss the fact that the same dataset ranks some traditions much higher in congregation count than in adherent count. If you only quote congregation totals, you miss how large some adherent bases are even when the tradition is relatively compact (ARDA U.S. Membership Report 2020).
The cleanest reading is to treat the list as a comparison tool. It answers questions like which traditions are broad, which are dense, which are top-heavy, and which maintain a large membership base with a relatively compact congregation footprint. Those are the practical comparisons that church charity statistics can actually support.
