<p>the graduate students have a completely seperate campus on the other side of town, with their own buildings, chapel, and dining facilities.</p>
<br>
<p>well, the "graduate college" to which you refer houses only a small fraction of all graduate students. many others grad students live in university-owned housing at other edges of campus, and others still live in non-university housing in town and elsewhere. just as a factual note, princeton houses a much higher fraction of its graduate students than do its peers; it almost has to, because housing in princeton is so scarce and therefore so expensive. also, while the graduate college does have its own dining and certain social facilities, including the beloved "d-bar," it does not have its own chapel. the architect of the complex, the great ralph adams cram, wanted to eventually add a third court for "fellows" complete with such a chapel (where mass would be read in latin as in the old tradition) but alas, the university never commissioned it. see, if you wish, his autobiography, "my life in architecture."</p>
<br>
<p>Harvard, for example, has 6,000 undergrads and around 9,000 graduate students, I believe. </p>
<br>
<p>more like 12,000 grad and professional students, for a graduate-to-undergraduate ratio of roughly 2:1 (cf. P's 1:2, Y's 1:1).</p>
