With demand flat or falling to 2035, the model gives providers no such escape and does not fit its cost-cutting to the faster historical recovery. Deficits are therefore stickier in the model than in the recent past; this is a finding to test, not an assumption to hide."

'priceGroup' approximates the OfS funding price groups: A (clinical medicine, dentistry, veterinary science), B (laboratory science, engineering, technology, and pre-registration health courses), and everything else (C and D). The mapping is at subject level, so it is approximate: in medicine only the clinical years are group A, and some subjects allied to medicine are not group B. Earnings and employment: median earnings and the share in sustained employment or further study five years after graduation, for UK-domiciled first-degree graduates of English providers (LEO, 2023-24 tax year), averaged across each subject's CAH3 subjects weighted by graduates. Students by subject at English providers matched to an OfS finance group, from HESA Table 49 (all levels and modes, CAH3 subjects summed to the model's subjects in subjects.json). Withdrawal: of provider-subject pairs (CAH3) with at least 20 students in 2019/20, at providers still reporting students in 2024/25, the share with fewer than 5 in 2024/25; recoding between CAH3 subjects counts as withdrawal, so rates are upper bounds.
