<p>Obviously, that number includes only undergrads based in Wharton, and not dual-degree candidates based in another undergraduate school (or else there would be double-counting). Also, you have to throw external transfers into the mix, since Penn enrolls around 250 or so a year, including some in Wharton.</p>
