>Not to split hairs but those stats are from 1910 [?!]

Not sure what to say . . .
Here are the more up-to-date
numbers, and their link:

---------------------------------------------------------

Largest Religious Groups in the United States of America

Christians in the US (1990) = 151,225,000

Protestants in the US (53%, 2001) = 80,149,250

Catholics in the US (23%, 2001) = 34,781,750

(Pew Research Council percentages)

It makes sense that Protestants outnumber Catholics as America was essentially founded on persecuted protestants fleeing the Roman Catholics and evil Anglican/Episcopalian bishops in England. I'm actually surprised the numbers are that high for Catholics.
