So this is the grand synthesis/consolidation note. I need to assemble ALL durable claims across every facet:

1. Core answer (grow/shrink bifurcation)
2. Demography
3. Signaling / enrollment demand
4. Program mix × region
5. Cost structure
6. Research function
7. Regional variation

Let me compile the full durable claims inventory from the notes:

**Core answer:**
- "Grow or shrink" resolves as "both" — the system thins and bifurcates; region- and stratum-specific.
- Total enrollment drifts ~19M → ~14–15M by 2045 (Unverified).
- Degrees conferred roughly steady while institution count falls — "thins, doesn't shrink."
- Median campus roughly halves in enrollment.
- AI is an accelerant/sorter of existing trends, not the primary cause. Two-front squeeze: fewer 18-year-olds AND weakened degree signal.

**Demography (load-bearing, sourced):**
- Births 4.32M (2007) → ~3.59M (2023), ~17% decline (CDC/NCHS).
- HS grads peak ~3.9M/yr ~2025 (WICHE "Knocking at the College Door").
- Birth dearth hits college age 2029–2037.
- Northeast/Midwest/Plains lose 10–20% college-age cohorts (WICHE); TX/FL/TN/GA/Carolinas grow.
- Net domestic migration to Sun Belt (Census Bureau).

**Signaling:**
- Screening vs insurance decomposition: screening dies first (AI-verified work samples cheaper than proxy-filtering); insurance (blame-shifting/liability cover) is sticky residue, persists in regulated/litigation-exposed sectors through 2040s. Post-2035 degree demand tracks a sector's legal/liability regime before it tracks region.
- Licensed/statute-gated fields hold (nursing, law, accounting, teaching; catastrophic-failure: engineering, medicine); super-selectives hold.
- Mid-tier unlicensed BA premiums compress 30–50% real by mid-2030s (Unverified).
- Fastest collapse in generalist white-collar fields (business, communications, generic liberal arts).
- By ~2035 median degree = positional luxury marker; degree reprices from entry ticket to exit credential (licensure, grad gatekeeping, late-career management).
- "AI doesn't kill the degree; it kills the undifferentiated degree."
- Credential-value decay hits by major before by institution — compositional churn; campus fates track program mix.
- Pre-AI drift: Burning Glass Institute "The Emerging Degree Reset" (~46% of middle-skill postings dropped degree requirements 2021–22); HBS "Dismissed by Degrees".
- Stanford Digital Economy Lab "Canaries in the Coal Mine" (2025) — early-career employment declines in AI-exposed occupations.
- Total degree-seeking enrollment falls 15–25% below demographic baseline by 2045 (Unverified).
- Mid-market enrollment contracts 25–40% by ~2035 (Unverified).
- Micro-credentials are a middle-market illusion — complement at top, fail to stabilize bottom.
- Two brakes: AI application floods push employers back to crude degree filters; elite alumni networks.
- Two brakes... wait, the two brakes claim: "AI application floods push employers back to crude degree filters; elite alumni networks" — I should keep the brakes since the consolidation said keep every claim that still holds.
- Elite degrees gain value BECAUSE verification makes mid-tier signals redundant.
- Degree survives as insurance (sorting, licensure, networks), not instruction.
- Demand migrates to "protected degree + AI skill stack."

**Program mix × region:**
- Licensed vs unlicensed share of credit hours = dominant predictor; region governs whether winning mix is reachable.
- Licensed expansion takes 7–10 years (clinical placements, faculty pipelines, state approvals) — longer than declining-region runway → decline locks in.
- SEC/Sun Belt publics +10–25% seats through ~2040 as legislatures fund as economic development.
- Northeast small privates without licensed core: −30–50% by 2040 (Unverified).
- "Program mix picks the winners, regional demography picks which losers can still switch."
- Flagships everywhere partially
