One reason adcoms are interested in Native youth are because of dismal educational statistics in this group. This is the only URM group whose graduation rates have gone down, not up.
How bad is it? Native youth: only 78% graduate from high school. For students attending federal Bureau of Indian Education schools, only 53% graduate from high school (my daughter attended one, was #1 in her class (the “Harvard” of BIE schools, and has transferred.)
According to the ACT, only 11% of Native youth who took the ACT were college ready (scored 18 or better on English, 22 or better on math.) Almost 80% of Asian youth scored at that level.
Harvard’s charter is to educate Native kids. In 2014-5 (latest data set), 2 out of 1650 freshmen were Native. Including those 2, there’s only 14 Native kids out of 6,636 undergraduates. For comparison: 657 Hispanic, 463 AA students.
OP, I respect you referring to yourself as Hispanic and/or Native (and I am Native.) You are definitely indigenous, and I think writing about your Quechua heritage and language preservation would make a compelling essay.
Best of luck with your future plans.
