I think it's actually a little misleading, not to mention discouraging, for applicants to look at the numbers from specific schools. The ratio for any individual school has very little to do with how competitive it is to get in. For example, the ratio of matriculants to applicants for both Harvard and NYU is very, very low, but for completely different reasons.
Harvard is a very competitive school. The ratio here is so low because tons of people apply on the off chance that they will get in; I'm sure relatively few people who get accepted to Harvard turn it down.
NYU is a much less competitive school. The ratio here is so low because tons of people apply as a backup. Many, many of the people who are accepted here opt to go somewhere else.
So you really can't gauge your chances of admission by looking at an individual school's matriculant to applicant ratio. If you have reasonable stats and apply to a good variety of schools, your chances of gaining admission should be pretty darn close to 1:2. Best of luck to everybody waiting for those magic letters. 🙂
