These 33,000 are subdivided into “6 major ecclesiastico-cultural mega-blocs”, and ordering them by denomination size we have (I am rounding up or down slightly for convenience, using year 2000 figures) :
Independents (about 22000)
Protestants (about 9000)
“Marginals” (about 1600)
Orthodox (781)
Roman Catholics (242)
Anglicans (168)

I think this is a fairly reputable source. Of course the number has probably grown since 2001. THis chart isn’t easy to transfer but you get the idea…
