Yes, Runallday, that's it. Thanks! Ibfailure, if you check out the Open Magazine issue that runallday linked to, it shows survey data from 2010 on pg 8. There's also a link I found to the 2009 one:
Open Magazine (spring 2009) .
The 2009 survey provides percentages. In it, about 11% of Rice students self-identified as non-heterosexual (ie 5% homosexual, 5% bisexual, 1% other). A friend of mine who worked for Open said this percentage masks persons who report as heterosexual, despite having same-sex attractions and experiences, because they may not be comfortable admitting anything otherwise. Other revealing questions answered by self-reporting heterosexual students in the survey support her assessment; she thinks the percentage is closer to 15%.
