This is a quote from the Forbes article you linked to in your post #19 (which was an interesting read, thanks)

Just over half of the population are ethnic Russians, a quarter are ethnic Ukrainians and most of the remainder are Crimean Tatars
I really think it is an accepted fact that Crimea is made up largely of a Russian population, and I will look for other references to post when I have more time. I was just getting ready to play a game with my son so I can't right now.

Also looking at demographics for the entire country of Ukraine really isn't applicable to the point of Crimea.
