Usually, there is no way to know the state of residency of students accepted to any particular medical school, especially private medical schools. If you were able to look at a list of students actually ENROLLED, or were given a state by state breakdown of students actually enrolled, you should never conclude that it reflects data on the medical school's geographic preferences. What such lists more often reflect are the geographic preferences of ACCEPTED AND ENROLLED students who had choices of where to attend. Many students, by no means all, given the choice, tend to prefer schools in their own region.
Even if you look carefully in the MSAR at the tables on the right bottom of each 2 page spread for each medical school--INFORMATION ON THE ------- CLASS FIRST YEAR CLASS--, you will notice that the last line, NEW ENTRANTS, refers only to NEW ENTRANTS, not applicants accepted.
Moreover, account must also be taken of the population size of the state when looking at in-state and out-of state figures. Johns Hopkins, a private medical school in Maryland, a small state, in 2000-2001 had only 417 Maryland residents apply, while 6,108 non-residents applied. Ten times as many non-residents were interviewed. That year's class of 118 had only 7 Maryland residents. Nothing can be concluded about Hopkins' preferences.
