*The UCC's 2007 finish among the 25 largest U.S. Christian denominations. The UCC's 21st-place rank remained unchanged for four years in a row despite a 3.28 percent membership loss last year.

Six denominations reported an increase in membership in 2006, while eight reported a decrease. Eleven denominations failed to report at all or reported the same numbers as previous years, suggesting the ranking may be the best thing going, but not completely accurate.
