Interesting survey??

Well I logged onto my school account and a messaged popped up. Okay, this is probably one of the weirdest messages...well maybe the message wasn't weird it was the demands in the message. Apparently I have to fill out a survey updating my ethnicity. It even said there was a link I could go to if I needed to change it again later. UMMMMMMM.....WOW! According to this odd message it was required for the university to create this survey and to make the link available for us in case we needed it. My race/ethnicity has never changed, and I am almost sure it never will. Am I misunderstanding this message, am I completely missing the point? ughh.
