Since the sky seems to be falling here on SDN, I'll post some numbers:
There were (last I heard) 538 active residency spots with 568 CASPR applicants from the class of 2013. This was prior to a final part II pass rate. So if we apply a traditional 90% part II pass rate (after the 2nd admin), you get 512-ish 4th years competing for 538 spots. That leaves room for the most recent programs to close and for students who haven't matched in the past to land a few spots. Remember that pretty much EVERY year there are "qualified" graduates who still don't get residency positions and it has nothing to do with a "shortage". It's a direct product of some iffy admissions and academic requirements at certain schools. In the spring of 2012 there were 4th year students who had entered CASPR and still not passed part I...somebody let students continue to move through school despite that fact that they were not going to be eligible for residency, and then let them "graduate" because they had met the school's requirements (Boards are a licensing requirement and have nothing to do with a school's diploma).
Every year, around this time, some terrible residency shortage rumors/posts/fear mongering is done. It generally starts from a pre-pod and then is supported by students from a few of the schools who take absolutely ZERO responsibility for their students doing poorly on boards or not getting residency programs. I remember as a pre-pod, some 3rd and 4th years ("brodiatrist", I believe, was one of them) from a certain school who were told by their Dean that the shortage was real and that everyone else had failed them. It was the APMA's fault, the NBPME's fault, the CPME's fault, the Residency Directors' faults, etc. Well guess what, there has yet to be a true "shortage" and it looks like this year may be no different (depending on the 2nd time national pass rate for part II).
Has the residency genesis been slower and to this point less successful than we all hoped? Absolutely. Are you going to get a residency if you are an average student with an average work ethic? Absolutely. So I've yet to get worked up about it, personally.
