I think it's an issue of cultural norms and social differences between those in different races. Social fraternties/sororities are strongly social (sorry about stating the obvious), so there're going to be correlated strongly with race because culture is strongly correlated to race.
That said, I've seen a few exceptions. For example, I've personally met a black girl who's a Tri-Delta at a SEC. She expresses annoyance when people ask why she's not in a NPHC.
If you feel that a NPC organization is something you're interested in, by all means, rush and see if you find a fit.
