That’s playing fast and loose with the numbers. When comparing enrollments, one should count only areas in which undergraduates and graduate students overlap. To use one of your alma maters as an extreme example, what sense does it make to include medical students in Cornell’s total? It’s in NYC, nowhere near the main campus and its undergraduates. This is not unusual; vet schools are quite often located elsewhere, for example, as are things like JHU’s IR school and NYU’s IFA. Even when things are located on one contiguous campus, law and other professional schools are often shoved to one corner of campus with their own buildings, libraries, career centers, etc. </p>
<p>To use examples with which I am familiar:</p>
<p>Duke has 6500 undergraduates and 7000 graduate students, thus falling into your first category. Only 2800 of those graduate students are in arts & sciences or engineering, however, and thus competing with undergraduates for attention. That’s a total of 9300 students overlapping.</p>
<p>UNC has 18,500 undergraduates and 11,000 graduate students, thus falling into your second category. Counting all of the categories in which there is overlap between the two (arts & sciences, business, education, library science, dentistry, journalism, nursing, public health), there is a total of 18,500 undergraduates and 7000 graduate students – for a whopping total of 25,000 students. That is more than double that of Duke’s overlapping population (and trust me, you can very much detect that difference).</p>
