Very interesting article here on the effect of sibling status, diversity, and donations on admissions at top schools --
http://www.nytimes.com/2011/09/06/nyregion/at-elite-new-york-schools-admissions-policies-are-evolving.html?_r=1&pagewanted=all . Lots of details on issues that interest many people here. I have not even finished reading it yet. I'll update later after I finish reading it. Enjoy.
ETA: I am putting below some of the quotes I find most interesting.
NYTimes article wrote:"Of those 62 spots at Trinity, one of New York’s most competitive schools, 33 were taken first by qualified siblings of Trinity students. An additional 11 went to children of alumni, who also get a leg up in the process, and one more belongs to the child of a staff member. That left 17 spaces for families with no ties to Trinity, giving those without connections a 2.4 percent shot at the prize."
On the idea that sibling preferences may hurt family donations in a tough economy: “You get more money from five families than two families with five children.”
"29 percent of students at 31 private schools in New York City were minorities in the last school year, up from 20 percent a decade earlier ... Minority students make up half of Fieldston’s lower school now ... Dalton’s 2011-12 kindergarten class is 47 percent minority ... Trinity’s 45 percent."
"Administrators at several schools, along with consultants, said the sibling crunch had intensified in recent years both because families have gotten larger and because families are staying in the city longer. The increased demand has led schools to rethink not only sibling and legacy preferences, but everything about the application process."
