Need statistics on how many Russian speaking Christians live in USA
and Canada.   Christians Groups including: Orthodox, Pentecost,
Baptist, New Age, Lutherans, Seven day Adventist.If available how do
they spread by regions.
.

I'll guess 100,000 Russian Orthadox speak Russian intelegibly in the
USA and Canada. Half that number speak fluently, and twice that number
can get the general meaning listening to one or more Russian dialects.
I would guess only 1/10th that many in each of the demominations you
mentioned; mostly resent converts to these denominations. In each case
this is the denomination the person would mention. They may be quite
inactive at present and were not necessarily born in Russia.   Neil

I was surprised by the number of persons in the USA that speak Russian
in their home as answered by bobby g. There may be about that number
in Canada, so you should likely scale up by about thirty times my
previous answer.  Neil

This site, that deals with Russian speaking Christian groups, might help you: 

"According to 1990 Census Data, 241,798 Americans speak Russian at home"

Neil. thank you for you comments. It gave some ideas, but I really
need cold numbers. Sound like question is complicated so I decided to
increase premium if it'll help
