End 2002: The last year the ICOC collected membership data centrally was 2002.
Latest 2004 membership for Brazil and Argentina churches are informal estimates only.
Membership statistics collected by icocinfo.org are unofficial. We encourage the cooperative sharing of this information, believing that these numbers are important to Christians interested in church growth, missions and church planting. If you would like to share data for your church or have access to membership information for churches in our fellowship, please contact .
As a matter of policy, we do not publish church-specific information where doing so might endanger the local church. However, such information is included in aggregate under the heading "Underground."
For a closer look at the formulas we use to calculate the "best available estimate" in the absence of complete data, download this Excel file. To report errors of fact or outdated information, contact .
