miglo;
UHS03 is right, the NRMP is only one of the residency match programs that you can pariticapate in as a DO (there is the AOA match and the 'MD' match; NRMP). The number of unmatched DO students presented each year for the NRMP is misleading for a couple of reasons.
First, many DO grads will participate in both the NRMP and the AOA match. Since the results for the AOA match come out earlier than the NRMP results (Feb vs March), those who matched in an AOA program may not withdraw from the NRMP, and also don't submit a rank list thus being counted as not matching. Second, many DO students sign contracts before the match. Again if they don't withdraw from the NRMP and don't submit a rank list, they are counted as not matching.
Of course there are those DO's who legitimately don't match. A few of my classmates ranked very competitive programs in OB/Gyn and surgery and didn't match and one ended up scrambling for a spot and the other went to an AOA program for internship.
Don't worry, as a DO grad, you'll find a residency spot in any field you want, be it AOA or ACGME (AKA: MD). Good luck...
Correction from RBorhani:
The 31% does not include those that did not turn in their rank order list as indicated above. It is % of unmatached ACTIVE applicants i.e. there were 1,451 DO applicants 185 withdrew and 282 did not rank any programs ... of the remaining 984 applicants 671 matched leaving 313(32%) unmatched.
