🏛️ Your state's public flagship
University of Missouri-Columbia
The in-state tuition gap is the flagship's biggest draw — most in-state families pay far less than the out-of-state sticker. Average net price after aid runs about $20,268/yr. Admission odds depend on your student's GPA and test scores, not which high school they attend.
Source: IPEDS admissions, tuition & enrollment + College Scorecard net price. Flagship = the state's primary public research university.
Enrollment trend & projection
Private school enrollment comes from the NCES Private School Universe Survey (PSS), which is collected every other year — not annually like public-school data. The most recent published collection is 2021–22; NCES targeted spring 2026 for the 2023–24 release — we'll load it as soon as it's published.
If the recent trend holds…
At its recent rate of -5.2%/year, projecting from 2022's 271 students:
≈ 64 fewer students by 2027 — a real revenue/relevance risk worth getting ahead of.
An extrapolation of the recent trajectory, not a forecast of the school's plans; ignores one-off shocks.
Revenue at risk
At tuition per student, the 64 students projected to be lost by 2027 represent ≈ $1,024,000/year in tuition at risk.
Tuition is an editable estimate (PSS doesn't publish tuition) — set it to your school's figure.
