Math BS => Sociology PhD?

<p>Facts:</p>

<p>1) I'm a math major. This is because I like proving stuff better than sitting in lab spilling mercury on things.
2) I really like sociology. Specifically I like the idea of doing research and getting statistics and coming up with neat models about human society. Which means I want to be a grad student in sociology, but I have no idea what I want to do after that.
3) I go to Caltech. We don't really have a sociology program here. But even if we did I would still probably want to be a math major because I like proving stuff better than writing essays.</p>

<p>Questions:</p>

<p>a) Will it hurt me that I'm not getting a BS in sociology? How much? I was thinking maybe I could salvage my app by saying I can use math to build cool models of stuff.</p>

<p>b) What do sociology PhDs do after they graduate, aside from academia?</p>

<p>c) I'll have at least two papers before I graduate, but they're in a completely unrelated field (fruit fly stuff). Will they help my application?</p>

<p>d) How can I demonstrate my interest in the field (aside from taking classes?)</p>

<p>Thank you for your advice!</p>

<p>I know of a physics major from Caltech who got a PhD in social sciences or something generic like that. I can’t tell you much more though.</p>
