Yes, those are the stats for rads in general...for # applicants. Since most pgms have about 100 apps/slot, this shows that people really apply broadly.
You can also look at the statistics for # interviewees/slot.
For specific pgms, your best bet is to call, but that would be viewed as odd. But just use an alias and talk to the pgm coordinator. They vary from about 7-30 interviewees/slot.
Some pgms on FReida list # interviews 'last yr' that they offered. But this is self tabulated, but prob close to the truth. And it may not be updated yet. And many prgms don't list that info
