If you'll tolerate a bit of thread drift, I'll admit I'm a bit annoyed by the word "Caucasian." It ought to be considered an obsolete anthropological term. Wikipedia says:

The term itself derives from measurements in craniology from the 19th century, and its name stems from the region of the Caucasus mountains, itself imagined to be the location from which Noah's son Japheth, traditional Biblical ancestor of the Europeans, established his tribe prior to its migration into Europe.

If you're going to call people African-American, Asian-American, Native American, etc., then obviously the equivalent term is European-American. Why not use it?

(People in other countries will have to work out their own terms, I suppose.)
