This is an interesting question Caryl!  In many ways it would be great to see such data; but as a disabled person myself - I have to ask if there is any such data to cover non-disabled students (apart from nationally) regionally and/or institution by institution?  If there is not, then to produce and/or manage to find such data would be discriminatory towards disabled graduates if it is collected without their permission.  If some graduates declined to allow their personal data to be used in research, this of course would help invalidate the research per se.
