The 2007 Yearbook of American and Canadian Churches is out, and as always the statistical information is interesting. Among other things, it lists the 25 largest denominations (not all of them genuinely Christian, but the NCC publication doesn’t try to separate the true from the false, but simply takes them on self-description, which is fine for this particular work). Here they are, along with any reported increase or decrease:

1. The Catholic Church, 69,135,254 members, reporting an increase of 1.94 percent.
2. The Southern Baptist Convention (SBC), 16,270,315 members, reporting a increase of .02 percent.
3. The United Methodist Church (UMC), 8,075,010 members, reporting a decrease of 1.36 percent.
4. The Church of Jesus Christ of Latter-day Saints (LDS), 5,690,672 members, reporting an increase of 1.63 percent.
5. The Church of God in Christ (COGIC), 5,499,875 members, no increase or decrease reported.
6. National Baptist Convention, USA, Inc. (NBC), 5,000,000 members, no increase or decrease reported.
7. Evangelical Lutheran Church in America (ELCA), 4,850,776, reporting a decrease of 1.62 percent.
8. National Baptist Convention of America (NBCA), 3,500,000, no increase or decrease reported.

18. Pentecostal Assemblies of the World (PAW), Inc., 1,500,000 members, no increase or decrease reported.

25. Jehovah’s Witnesses (JW), 1,046,006 members, reporting a decrease of 1.56 percent.

To put these into broad categories: the United Methodist Church, ELCA, PCUSA, ECUSA, ABCUSA, UCC and Disciples are mainline denominations. The SBC, Assemblies of God, LCMS, Churches of Christ, and BBF are predominantly white, conservative Protestant denominations. COGIC, NBC, NBCA, AME, NMBCA, PNBC, PAW, and AMEZ are predominantly African-American Protestant denominations.
