<p>There are roughly 150,000 people per year who take the LSAT. Probably about 100,000 of those apply to law school. My undergrad has about 250 per year apply to l.s.. That is probably a reasonable guide for the top 25 universities - so let's estimate that about 6,200 of those 100k are from top 25 universities. Throw in huge state schools, which just have more people and therefore more applicants, such as UVA/UMich, and we can increase the estimate to about 7,000. Then let's take the top 25 liberal arts colleges - probably about 100 per year from each of them. That's roughly (emphasis there) 10,000 people from the top schools (not HYPMS, obviously, but really good, selective schools) - so 10% of the law school applicants are coming from these great schools. </p>
<p>As a thread a few months back pointed out, kids from the best undergrads tend to go to the best law schools. So if you are talking about elite law school admission, you're talking about the kids who are at the top schools, whether by transfer or because they started there.</p>
