On September 21, 2002, The San Francisco Chronicle featured an article on the Glenmary study. "Nationally, the study reflected growing spiritual diversity in the United States by including such once-exotic faiths as Islam, Buddhism and Zorastrianism for the first time...     But the way the study counted American Muslims - and did not include millions of African American Christians - has sparked a statistical brouhaha... Researchers estimated Friday that the report, titled 'Religious Congregations and Membership in the United States 2000,' does not include some 8 million black American Christians in such denominations as the National Baptists, the African Methodist Episcopal Zion Church and the Church of God in Christ." Details from the study can be found on the American Religion Data Archive Web site.
