Writing a paper on the financing of higher educational institutions in the US. I’m able to find good data on grants federal and state governments issue, but not data which is inclusive of loans disbursed to students which are used to pay for tuition. Really I’m looking to evaluate just how much American higher ed relies on the government for operating revenue.

Any suggestions? I know this ask isn’t very specific but I’m still in the research and surveying portion of this paper so really any good sources on federal student loans/university income streams would be helpful.
