Denny O'Neil is the guy who created Talia and Ra's back in the early 70s. A couple of decades later, he wrote a graphic novel called "Birth of the Demon" which showed us the origin story of Ra's al Ghul (his first discovery of the Lazarus Pit phenomenon, for instance). In that one, it was stated that Ra's met Talia's mother at the famous Woodstock event. The lady was of mixed Chinese/Arabic heritage, as I recall. I tend to take that as definitive since O'Neil was the original writer for Ra's and his daughter, and thus ought to know more about the family background than anyone else does. Also, he was also the editor in charge of the Batman group of titles all through the 1990s, so it stands to reason that he expected his own graphic novel to be Totally Canonical at the time it was published. (Granted, in the New 52 continuity, who knows how much has changed?)
"Birth of the Demon" also indicated that Ra's al Ghul was born and raised hundreds of years ago in a city somewhere in North Africa. (The city was not named for us; apparently it is no longer inhabited.) No telling how long his family had lived in that region -- he might have Berber blood, Moorish blood, Egyptian blood, who knows?
But if we arbitrarily assume Ra's is practically "pure Arab" in his genetic heritage (which I doubt), and that Talia's mother was a simple half-and-half mixture of Arab and Chinese (which may not be the accurate percentages), that would give us something along these lines:
Talia would be 3/4 Arab (from three grandparents out of four), and 1/4 Chinese (through one of her mommy's parents).
If so, then Damian would be about 3/8 Arab, 1/8 Chinese, and the other 4/8 would be whatever Bruce Wayne's own racial/ethnic heritage is. (Heavy on the White Anglo-Saxon Protestant ancestry, I expect, although at least one Bronze Age story indicated that he is a direct descendant of a bunch of Waynes who were successively the lords of an old castle in Scotland, which is not necessarily the same thing as "Anglo-Saxon" per se.)
