ymosko,
Frankly, research by posting a question such as this in the CR is not research that should gain you a graduate degree.
Certainly when all you are looking for can be accessed by doing a search for the actual sources reporting the information.
I doubt there is any way at al you can get the AIE for “Jewish” students in either place.
Busing is for all students, not just Yeshiva students.
Further, 25,000 to 2,590 does not calculate to 4 to 1, ratio. Something is very wrong with your numbers.
