In the following segment from the ABC World News, that first aired on February 16, 2011, it was reported that the Jehovah's Witnesses are the fastest growing denomination in America:
In the related online ABC World News article, "Membership of Pentecostal Church, Jehovah's Witnesses Up, Protestant Down" we read:
The Jehovah's Witnesses, known for their door-to-door preaching, had the largest growth of any single denomination. They believe secular society is corrupt, and that Armageddon is imminent. Famous members include Venus and Serena Williams. Membership shot up 4.37 percent in a year. (link)
And from the website of the National Council of Churches, we get the following statistics:

The total for the Jehovah's Witnesses is a bit misleading, for they are the sole denomination that I know of which only counts ACTIVE members in their membership total. A more accurate comparison with the other denominations would be the attendance numbers of their yearly "Memorial Service", which for the United States in 2010 was 2,485,231. (Full, worldwide statistics available online HERE.)
I find these statistics quite interesting, and given some recent cryptic comments made by the American Reformed "pastor" David King (link to post) in the combox of THIS RECENT THREAD at the blog of the secretive, post-deleting, gent who goes by the name "Turretinfan", thought-provoking.
[FYI - I see that "Turretinfan" has yet again deleted a number of my responses in the above mentioned thread; seems I need to reproduce those posts here at AF in a new thread.]
Grace and peace,
