Not really? Yes there are other schools that are worse than Stanford, sometimes significantly more but take a top public school like University of Texas which has 5x as many students from the bottom 60% as from the top 1% (5.4% and 27.7%)
Stanford is at 17.5% and 18.6%.
For comparison Harvard is better, MIT is significantly better, on par with Texas, Yale and Princeton are slightly worse.
My point was about whether or not the Stanford Students' wealth distribution is more skewed towards higher family income, as compared to other schools.
And additionally, whether or not these differences are driven by academic achievement (which is often higher in higher income families, for various reasons if not more money spent on good grades) or other reasons.
Stanford is at 17.5% and 18.6%.
