Thank you for your unpleasantly phrased and confrontational feedback.

The software I use to process this information has a lot of trouble handling "check multiple boxes". Adding "biracial" would be strictly inferior to just asking people which of their two races they identify more with, since biracial gives no race information.

You cannot infer relationship status from number of partners, because status differentiates "married" from "in a relationship", which the partner question cannot do.

So far each one of the three computer options has been selected by significantly more people than the "other hard sciences" group. There are 174 people selecting "practical computing", compared to 10 people in all of "hard science". I base these categories not based on what people think is the "central science" but on what will best distinguish between large categories of people.
