Residency salaries vary widely from program to program. Every program you look at will probably have a different salary. I'd say the range is probably $35,000 - $55,000.
The figures you posted are ANNUAL salaries for each year of residency. i.e, you get paid $41,146 for your intern (PGY1) year, $42,481 for your second year of residency (PGY2), and so on.
