Question:

How many different nationalities of caucasion people are there?

Best Answer - Chosen by Asker: That is unanswerable. Use of the word caucasian is a social construct as any anthropologist can tell you and a leftover from going on a century ago. Other than that there is the geographical region in eastern Europe known as the Caucasus which is generally Georgia, Armenia, & Azerbaijan.
