than at other schools.
I’ll try to find that ND graphic from last year, which I think shows the # of legacy applicants and % of the class who are legacies. Without those figures the degree of preference is impossible to measure.
It doesn't say that legacy applicants have a greater chance of admission than a non-legacy applicant for a given level of credentials. It says that the portion of all legacy applicants admitted is much greater than the portion of all non-legacy applicants admitted.
This might be a measure of loyalty. That is, for ND compared to other schools, a greater number of highly qualified sons and daughters apply.
The article mentions this as a problem for achieving ethnic and economic diversity (which it is). It doesn't attempt to assess whether legacy applicants get preferential treatment.
However, I believe that to the extent an apples-to-apples comparison is possible, if two applicants have the same credentials, the legacy candidate is going to have a greater chance of admission. I am skeptical that the bona fides of the legacy pool are statistically superior to those of the non-legacy applicant pool to justify the 2x admission acceptance rate.
I doubt ND can, or would, offer more granular data than that.
As others have said, one explanation would be that high achieving legacies tend to apply to Notre Dame at a higher rate than the high achieving general population.
One factor that might be relevant is that I'm pretty sure the "bubble" is rather "deep". That is, there is a large number of applicants in the range from just below to just above the cutoff for admission. Thus a slight advantage to anything (including legacy status) could lead to a significant change in the mix of accepted applicants.
