Church membership statistics at a glance
Church membership in the United States is changing in ways that are easy to miss if you only look at one denomination at a time. The clearest pattern in the latest Pew Religious Landscape Study is that formal Christian identification is still the majority position, but the mix inside that majority has shifted, and the unaffiliated share is now large enough to reshape how local churches think about reach, retention, and participation (Pew RLS 2025).

What church membership statistics actually measure
Church membership statistics can describe very different realities depending on the source. Some datasets measure self-identification in a survey, some count official rolls, and some report participation or operational totals such as congregations, attendance, baptisms, or giving. That is why a single headline number can be misleading if it is not read in context (Pew RLS 2025; SBC Fast Facts 2025; ELCA 2024 Summary of Congregational Reports; JW 2024 Grand Totals; Fides Catholic Church Statistics 2025).
There are three especially important categories here.
- Self-identification asks what religion a person says they belong to.
- Official membership asks whether a person or family is formally enrolled on a church roll.
- Organizational statistics count the institution itself, such as congregations, baptisms, attendance, or financial activity.
That distinction matters because a person can identify with a faith tradition without formal membership, and a member on paper may not be active. The best way to interpret church membership statistics is to compare source types rather than treat them as interchangeable.
What the latest U.S. survey numbers say
The newest Pew Religious Landscape Study provides the clearest national snapshot in this dataset. Its headline is simple: Christianity is still the majority identity in the United States, but the majority is smaller than it used to be (Pew RLS 2025).
Christian identification is still the majority, but it has narrowed
In 2023-24, 62% of U.S. adults identified as Christian (Pew RLS 2025). That is still a large majority, but it is notably lower than 78% in the 2007 Pew RLS and 71% in the 2014 Pew RLS (Pew RLS 2025). The direction is unmistakable: the Christian share has fallen across the study series.
A compact way to see the trend is below.
| Measure | 2007 | 2014 | 2023-24 |
|---|---|---|---|
| Christian identification | 78% | 71% | 62% |
| Protestant affiliation | 51% | n/a | 40% |
| Catholic affiliation | 24% | 21% | 19% |
| Mainline Protestant | 18% | n/a | 11% |
| Evangelical Protestant | 26% | 25% | 23% |
| Historically Black Protestant | 7% | n/a | 5% |
| Religiously unaffiliated | n/a | n/a | 29% |
The overall Christian share is still the broadest indicator, but the denominational breakdown shows where the loss is coming from. Protestant affiliation fell from 51% in 2007 to 40% in 2023-24, while Catholic affiliation fell from 24% to 19% over the same period (Pew RLS 2025). Mainline Protestants fell from 18% in 2007 to 11% in 2023-24, evangelical Protestants from 26% to 23%, and historically Black Protestants from 7% to 5% (Pew RLS 2025).
The unaffiliated share is now too large to ignore
The religiously unaffiliated accounted for 29% of U.S. adults in 2023-24 (Pew RLS 2025). That group is not a single viewpoint. It includes 5% atheist, 6% agnostic, and 19% who describe their religion as nothing in particular (Pew RLS 2025).
That mix matters because “unaffiliated” is a category of absence, not always a category of rejection. For churches trying to understand local attendance patterns, the important takeaway is that the unaffiliated share is no longer a fringe segment. It is large enough to affect recruiting, neighborhood outreach, family formation, and the surrounding cultural expectation of religious participation.
Non-Christian religions also remain part of the picture
Non-Christian religions accounted for 7.1% of U.S. adults in 2023-24 (Pew RLS 2025). Within that group, 1.7% identified as Jewish, 1.2% as Muslim, 1.1% as Buddhist, and 0.9% as Hindu (Pew RLS 2025). These shares are smaller than Christianity and the unaffiliated category, but they are not trivial in a national membership picture.
The same Pew data also show that immigrants were 14% non-Christian versus 6% among U.S.-born adults in the 2023-24 RLS (Pew RLS 2025). That kind of split is useful because it reminds readers that church membership statistics often reflect broader demographic change, not only denominational behavior.
Gender differences show that membership shifts are uneven
One of the more striking Pew findings is that the share of women saying they were Christian fell from 82% in 2007 to 66% in 2023-24 (Pew RLS 2025). That is a substantial drop and suggests the overall change is not evenly distributed across demographic groups.
For readers looking at church vitality, demographic unevenness is a useful warning. A church may see stable attendance in one segment while the broader national pattern still weakens. Averages hide that kind of variation.
How major Christian groups compare
The national survey numbers show the broad direction, but organizational statistics reveal how different institutions report scale. The comparison is imperfect because each body counts something different, yet the numbers still show a practical contrast between broad affiliation, institutional membership, and active participation.
Side-by-side view of major bodies
| Group or source | Latest reported figure | What the number represents |
|---|---|---|
| Southern Baptist Convention | 12,722,266 | Total membership (SBC Fast Facts 2025) |
| Southern Baptist Convention | 46,876 | Cooperating churches (SBC Fast Facts 2025) |
| ELCA | 2,677,239 | Baptized members as of 12/31/2024 (ELCA 2024 Summary of Congregational Reports) |
| ELCA | 8,386 | Congregations as of 12/31/2024 (ELCA 2024 Summary of Congregational Reports) |
| Jehovah’s Witnesses | 118,767 | Total congregations in 2024 (JW 2024 Grand Totals) |
| Jehovah’s Witnesses | 9,043,460 | Peak publishers in 2024 (JW 2024 Grand Totals) |
| Worldwide Catholic Church | 1,405,454,000 | Catholics as of June 30, 2023 (Fides Catholic Church Statistics 2025) |
| Worldwide Catholic Church | 17.8% | Share of world population (Fides Catholic Church Statistics 2025) |
The Catholic figure is the largest by far because it is a global count, not a national U.S. denomination count. The SBC and ELCA figures are national or organizational membership totals, while the Jehovah’s Witnesses figures mix congregational structure with participation metrics. That is why direct comparisons should be read carefully rather than treated as equivalent membership measures.
Southern Baptist Convention: scale plus activity metrics
The Southern Baptist Convention reported 12,722,266 total membership in its 2025 Fast Facts (SBC Fast Facts 2025). It also reported 4,304,625 weekly worship attendance, 2,567,048 weekly small group Bible study attendance, 250,643 baptisms, and 46,876 cooperating churches (SBC Fast Facts 2025).
Those additional numbers matter because they show the difference between membership and participation. A membership roll can be much larger than weekly attendance, and attendance can differ from small-group engagement. The same data set reported 3,522 overseas missionaries, 3,299 domestic missionaries, and 684 new churches planted, which gives another dimension to organizational reach (SBC Fast Facts 2025).
Financially, the SBC reported $9,558,032,631 in undesignated receipts and $446,641,957 in Cooperative Program dollars given, with 4.67% average of undesignated receipts given through the Cooperative Program (SBC Fast Facts 2025). These are not membership counts, but they help explain how the organization sustains its structure.
ELCA: baptized members, confirmed members, and participation
The ELCA reported 8,386 congregations, 2,677,239 baptized members, 2,120,543 confirmed members, and 1,502,984 active participants as of 12/31/2024 (ELCA 2024 Summary of Congregational Reports). It also reported 21,964 baptized membership accessions and 124,657 total baptized membership losses in 2024, alongside 172,384 total accessions and 81,238 total losses (ELCA 2024 Summary of Congregational Reports).
Those figures show how membership reporting can include both inflows and outflows in the same year. They also show why a single membership number rarely tells the whole story. The ELCA reported average giving per baptized member of $729.05 and average giving per confirmed member of $920.45, which adds a financial layer to the organizational picture (ELCA 2024 Summary of Congregational Reports).
Attendance data further complicate the picture. The ELCA reported average on-site attendance as 19.64% of baptized membership and average online attendance as 12.26% of baptized membership (ELCA 2024 Summary of Congregational Reports). That split suggests that the institution is tracking participation across channels rather than relying on a single attendance model.
Jehovah’s Witnesses: congregation density and preaching activity
Jehovah’s Witnesses reported 118,767 total congregations in 2024, with 21,119,442 worldwide Memorial attendance and 23,212 Memorial partakers worldwide (JW 2024 Grand Totals). They also reported a peak of 9,043,460 publishers, 8,828,124 average publishers preaching each month, and 7,480,146 average Bible studies each month in 2024 (JW 2024 Grand Totals).
The group’s 2.4% increase over 2023 is important because it shows year-over-year growth within its own reporting system (JW 2024 Grand Totals). It also reported 296,267 baptisms, 1,679,026 average pioneer publishers each month, and 867,502 average auxiliary pioneer publishers each month (JW 2024 Grand Totals).
This kind of reporting emphasizes participation, preaching, and organizational rhythm. It is a different statistical universe from a survey question about affiliation.
Why official membership and self-identification are not the same thing
The Pew data and the denomination data can be read together, but they answer different questions. A survey tells you what people say about themselves. A church report tells you what a church counts. That difference explains why Christian self-identification can still be 62% while a denomination’s active participation may be lower than its membership roll would suggest (Pew RLS 2025; SBC Fast Facts 2025; ELCA 2024 Summary of Congregational Reports).
The 2007 Pew RLS is especially useful because it asked whether respondents or their families were official members of a local church or house of worship. In that survey, 61% of Americans said they or their family were official members (Pew 2008 RLS). The subgroup differences were wide: 92% of Mormons, 83% of historically Black Protestants, 74% of evangelical Protestants, 76% of Jehovah’s Witnesses, 67% of Catholics, 64% of mainline Protestants, 68% of Orthodox Christians, 22% of the unaffiliated, and 30% of religiously unaffiliated respondents said they or their families were official members (Pew 2008 RLS).
Those figures show that official membership is not evenly distributed across religious categories. They also show that some groups maintain a stronger formal membership culture than others. For analysts, that means membership statistics should be read as a signal of institutional style as much as a measure of belief.
What the numbers suggest for churches and observers
The strongest pattern across the data is not simply decline, but differentiation. Some measures fall sharply, some remain stable, and some grow. Christian identification falls at the national level, yet large institutions still report substantial rolls, active participation, and significant organizational capacity (Pew RLS 2025; SBC Fast Facts 2025; ELCA 2024 Summary of Congregational Reports; JW 2024 Grand Totals).
For churches, three practical lessons stand out.
- Track membership, attendance, and participation separately.
- Compare your local data against the same type of metric, not against an unrelated headline.
- Treat the unaffiliated share as a core audience category, not a footnote.
For readers studying church membership statistics more broadly, the main lesson is methodological. The most informative question is rarely “How many members are there?” It is usually “What kind of membership is being counted, by whom, and for what purpose?”
That question is what turns a set of church numbers into a useful reading of religious life.
