Thanks for the useful feedback, everyone!
So, assuming that you are offered between 15-20k of support (comprised of scholarships and TAships), is it assumed that the PhD candidate will be able to subside off of that funding? Given the cost of living, that seems highly improbably. Are you expected to dig into savings, take out additional loans, and/or take on part-time work to account for further living expenses? Have you found that working during the summers can supplement your funding adequately? Basically, I'm trying to calculate how much debt I'll be walking away with!
I think living in NYC is skewing my perception of how much this is going to cost me (where I spend about 29,000 a year on living alone)!
