@MyOdyssey You misunderstand how the Common Application system works. There is no need “redact” information. Applications are transmitted electronically. Each university decides what their individual admissions officers see. At many Ivies (and it is my understanding that at Michigan too), the personal information page isn’t displayed on individual screens, nor are actual transcripts (the latter being summarised).
I think that many people believe that admissions officers still receive a stack of folders. Some universities may still do this, but most review applications on computers or iPads.
I also agree that many students still “work” their race etc., into their applications, especially through their essays (this is what happens in California). However, in the case of ‘holistic’ universities, I saw things like geography etc., play a much greater role than race.
