Solitary

Hi, I was wondering if anyone here is familiar with Berkeley's Sociology & Demography program? I am applying to Sociology PhD programs with social demography as a primary research interest and I was wondering if I should apply to the joint program at Berkeley instead of just sociology (you can't apply to both in the same cycle). The only things I am afraid about w/r/t/ applying to the joint program are 1) that I might realize a few years in that I mostly want to do sociology with some demographic relevance without actually doing formal demography and 2) that the joint program is more competitive to apply to. Is anyone here at Berkeley or familiar with the department and demography-inclined? What do you think are the pros and cons of the joint program versus getting a degree in just sociology, just specializing in demography? Thanks!
