@gallentjill (re legacy numbers) – I think that you need to keep in mind that many applicants have multiple attributes that make them more attractive applicants. The “legacy” status in particular may be highly prone to producing applicants who fit that definition – it’s not just legacy, but legacy plus. Because perhaps their Harvard-educated parent is also now a famous and influential VIP. Perhaps their Harvard-educated parent is a wealthy and generous donor. Perhaps as the offspring of Ivy-educated parents, that applicant has been essentially groomed since kindergarten to achieve, starting with the choice of elite schools have always been feeders for Ivies.
So yes, that is a very high number of legacies at Harvard. But that doesn’t mean that any particular student was admitted solely or even primarily because of legacy status. I’d note that the article you linked to was based on survey data from about half the incoming class – not hard numbers – so it might have been skewed, especially if legacy-students are for any reason more likely to answer surveys. But you can also drill down the data somewhat and see some patterns – see http://features.thecrimson.com/2017/freshman-survey/makeup/ http://features.thecrimson.com/2017/freshman-survey/makeup-narrative/
To start with, you see that they define “legacy” quite broadly – only about 18% had parents who went to Harvard – they get to the larger number by including siblings and extended family into the mix.
The legacies are also quite wealthy – and unfortunately the survey graphs do not give an overall picture of family wealth for Harvard students - but that certainly is a big chunk of full pay students with parental income over $500K.
Private vs public school? “58.7 percent of surveyed legacy students attended a private school, whereas 40 percent came from public school.” (Whereas overall, 60% of Harvard admits come from public schools – so that seems to extrapolate out to mean that among students who come from private high schools, about 30% are legacies, with only about 11% of those coming from public schools being legacies)
More: Of students who attended high schools that ranked, “73 percent were ranked in the top 2 percent of their class. 59 percent of students who had at least one parent attend Harvard and whose schools ranked, reported being in the top 2 percent of their class.”
And: “39.3 percent of first-generation students and 69 percent of legacy students were accepted into Harvard’s early admissions program.”
The legacy admit rate at Harvard historically was around 30% (based on a report from 2011 – at http://www.thecrimson.com/article/2011/5/11/admissions-fitzsimmons-legacy-legacies/ – it may have declined since then) — so yes, “legacy” students generally have bettter chances at admission than non-legacy – or at least rich legacy students who apply early are at a huge advantage, even more so if they attend a private high school and are in the top 2% of their class.
So bottom line: Harvard does not have a 30% legacy “bucket”. It does have admission policies that favor rich students who apply early, and a higher proportion of legacy admits come from that early applicant pool… but we don’t know if that stems from a preference or from a possiblity that a higher proportion of early applicants are also legacies.
