<p>In my search of geology department I have found that very few departments publish such data. Of the departments I applied to for my PhD I found averages for Minnesota and Wisconsin...</p>
<p>I'm not sure if Stanford publishes this material, I'd email the student services representative of the departments and ask if they can provide it or track such statistics.</p>
<p>I've had trouble finding those statistics as well.</p>
<p>But I'd caution you not to worry too much about them -- I get the feeling that those numbers are far less predictive for graduate school admissions than they are for undergrad, even for top programs. I suspect this may have to do with the vastly smaller applicant pool.</p>
