<p>I think you mean one female for every .67 males. </p>
<p>Total is about 10,400 males, and 15,300 females, as best as I can figure. Once you factor in the females at all colleges that are not on the open market due to having someone back home, wanting to meet a Williams, Dartmouth, or Yale guy, or not being an enthusiastic heterosexual, I’d say the sexual landscape is roughly 50:50 M:F</p>
