I wonder if the class of year reports are what race students reported on their application and the registrar numbers are what students checked off at registration? I didn’t crunch the numbers but there were a lot of unspecified or mixed race reported on the registrars report. I know for important legal document purposes my children report the most technically correct race but when they fill out stuff they don’t deem important they may self report one of their two ethnicities, no race, mixed, or both ethnicities. Perhaps when students fill these forms out on their own they are reporting something different than they did on their application?
