Here's offical info btw:
Yes: 96,77%, No: 2,51%, Total voted: 83,1%. In other words out of all people of Crimea who has right to vote 80,42% voted yes and 2,09% voted no to joinging Russia, the rest ignored referendum.
And a bit of "likbez" on Crimean Tatar situaion. The topic has been raised a couple of times during briefing before the referndum and afaik there were pro-Ukrainian rallies up to few dozens of people in Crimea here and there, mostly Tatars.
Tatars is about 12% of total Crimean population, political preferences is not as straightforward as some might think among them. There's so called Majlis of Crimean Tatars, that used to play a major role in the political life of Tatars in Ukraine, prime figures to know are Dzhemilev and Chubarov. Majlis is supposed to be an official representative of Crimean Tatars in the world, but I'm not sure about its actual legal status, de-facto actual support of it would be somewhere around 10-18% of all Crimeme Tatars, so they hardly could speak for all Tatars in Crimea.
Its natural to expect that majority of Majlis supporters would be situational allies with current Kiev authorities. Majlis people are the main recruit base for Hizb ut-Tahrir, an islamist organization (regarded as terroristic in Russia).
On another side there's about the same percentage of Crimean Tatars who are avidly pro-Russian -- business interests, relatives, military or navy service in Russia -- there's guy usually nicknamed himself as Ayup-han (pic below), talk to him if you want, he's Crimean Tatar. Everyone inbetween, ~60% of Crimean Tatars, are politicall indifferent, but given Tatars are traditionally run small businesses that either provides services or sell goods for recreational purposes (Crimea is popular resort), it's absolutely ok to expect big part of those to vote yes.
So there you have it. Bottomline. Considering all Tatars automatically pro-Ukrainian is a big mistake, to word it the right way -- they are least expected to vote yes, neverthelss I'm pretty sure a lot of them did exactly that.
//And if you think that Crimean Ukrainians en masse would vote any different than Crimean Russians -- just drop the topic altogether, you do not have any idea what's going on :D To word it in the shortest way possible -- your mistake here is you perceive this as strictly ethnical issue.
UPD: Guess the Tatar on the pic ;)
