Gmendese - I would say that in general the salary range is between $35,000-$55,000. Your salary increases every year of your residency. Location is also a big factor as well. I know that in CA, the salaries tend to be lower than Boston. The salary does not vary with regards to specialites within the same program. For instance, in the Harvard system, all residents are paid the same regardless of whether they are at Brigham, MGH, BID, or Spaulding. As an example, here's the link to what the salaries will be for me:
