Human Development and Family Studies PhD - what do you do?

[baby doll couture]

I applied to a Human Development and Family Studies program because I want to learn statistics and methodology for use in studies that have overlapping data points - such as shared community-level or family-level variables.

Now, I am accepted, and realized that I have no idea what people with this degree actually do!

Anybody up on this? Penn State says that recent grads are academics (good) and some are private sector (OK). But what are prospects like - are they highly regarded in the research community? I come from a Psych background (Master's in Forensic Psych) and I am not sure if I should go to this program, a sociology one, or quantitative psychology. They are very similar.

THANKS!!!
