I found the numbers for schools according to the 2005 edition of U.S. News and World Report's America's Best Colleges:
1)Harvard- 53M/47F
1)Princeton- 52M/48F
3)Yale- 50M/50F
4)UPenn-50M/50F
5)Duke- 51M/49F
5)MIT- 58M/42F
5)Stanford- 50M/50F
8)CalTech- 67M/33F
9)Columbia- 53M/47F
9) Dartmorth- 51M/49F
11) Northwestern- 47M/53F
So the top ten schools all have either equal numbers of men and women or more men than women, confirming what the report says about men not being missing at the very top schools. You have to getting to the 11th ranked school before you see more women than men. The first national university that I see with 40% men or less is #32 NYU, which is 40M/60F. Compare with some historically black schools:
Howard- 33M/67F
Hampton- 38M/62F
Fisk- 31M/69F
Clark Atlanta- 29M/71F
The conservative Christian college I attended between 98-00 was 70% female.
Notice that with the exception of the University of PA.they are all private(not subject to affirmative action)or Engineering schools.
