There was a survey given to 1,200 residency program directors of which 793 responded: (

The Ophthamology program directors ranked the relative importance of academic criteria for selecting residents as follows:
1) Grades in required clerkships
2) Number of honors grades
3) Class rank
3) AOA honorary membership
5) Senior specialty elective grades
6) USMLE Step 2 score
7) USMLE Step 1 score
8) Academic awards in medical school
9) Med school's reputation
10) Other senior elective grades
11) Published research
12) Grades in preclinical courses
Interestingly, the medical school's reputation is ranked much lower than grades and board scores. Also there is no mention of the applicant's state residency. It seems that whether you can match successfully depends mostly on your academic performance, rather than where you are from.
