The University at Buffalo Admits 70.48% of Out-of-State Applicants. 5.66% of Them Enroll

The University at Buffalo does not publish an acceptance rate. It publishes counts, and for the Fall 2025 entering class those counts are 45,637 applications and 36,780 offers — 80.59% when you do the division. Split by residency, the gap runs the way most families expect: New York residents admitted at 80.09%, out-of-state applicants at 70.48%, international applicants at 94.42%. That nine-point residency gap is real, but it is not what shapes UB's entering class. The number that does sits on the other side of the offer letter. Of the 3,340 out-of-state applicants UB admitted, 189 enrolled — a 5.66% yield against 15.67% in-state. Out-of-state students end up about 4% of UB's domestic first-year class, and nothing in UB's filings or SUNY's policies requires that.

The Decomposition

Cohort: Fall 2025 entering class, first-time, first-year, degree-seeking students, per UB's Common Data Set 2025-2026 residency table. The live file is UB's revised posting, CDS_2025-26_v2.pdf; no earlier version was located.

Show the math: an admit rate is offers divided by applications. In-state, 28,935 / 36,127 = 80.09%. Out-of-state, 3,340 / 4,739 = 70.48%. Overall, 36,780 / 45,637 = 80.59%. Yield is enrollments divided by offers. In-state, 4,533 / 28,935 = 15.67%. Out-of-state, 189 / 3,340 = 5.66%. Out-of-state applicants were 10.4% of the applicant pool and 9.1% of the admitted pool, but 4.0% of domestic enrollees (189 of the 4,722 in-state and out-of-state students who enrolled). The shrinkage happens between the offer and the first day of class.

The Admit-Rate Direction Flips. The Yield Gap Doesn't

Read only the Fall 2025 row and you would conclude UB holds out-of-state applicants to a higher bar. Across the three filings carrying this table, that is one year, not a standing pattern: out-of-state applicants were admitted at a higher rate than New York residents in Fall 2023 and Fall 2024, then a lower rate in Fall 2025.

Sources: UB Common Data Sets 2025-2026, 2024-2025 and 2023-2024, Section C1 residency tables. Totals: Fall 2024, 40,855 applied / 30,307 admitted / 4,264 enrolled; Fall 2023, 38,210 / 26,481 / 4,269.

Read the two halves against each other. The admit-rate columns cross over: a 6.19-point out-of-state advantage in Fall 2023, 2.83 points in Fall 2024, then a 9.61-point in-state advantage in Fall 2025. The yield columns never cross, never come within eight points, and run 2.3 to 2.8 times higher in-state every year. Whatever moved the admissions decision between 2023 and 2025 did not move the enrollment behavior.

International figures need the same three-year treatment and more caution. The rate reads 73.61% in Fall 2023, 60.43% in Fall 2024, then 94.42% in Fall 2025, while international applications fell from 5,744 to 4,771 and admits rose from 3,471 to 4,505. Each column sums exactly to UB's stated totals, but UB publishes no note explaining the jump, and we cannot rule out a change in how the category was reported. Treat 94.42% as the single year UB filed it, not a rate to plan against.

A 4% Out-of-State Class, With No Cap Requiring It

UB's Common Data Set Section F1 reports that 4% of Fall 2025 first-year enrollees are from out of state, international students excluded. That line describes the class that showed up. It is not an admit rate and not a selectivity signal — UB admitted 70.48% of its out-of-state applicants that year. The two numbers describe different stages, and the distance between them is the story.

We looked for a rule that would produce that 4% and did not find one. What we checked: UB's three Common Data Set filings; UB's Office of Institutional Analysis site; the SUNY University-wide Policies and Procedures library, whose title search returns no policy for residency, nonresident, or out-of-state and whose Academic Affairs and Student Affairs categories list no such policy; and the SUNY Board of Trustees policies page. None states a non-resident cap, quota, or residency target. We also went looking at the state education statute granting the SUNY trustees their powers, but the official legislature page blocked automated retrieval, so we rest no claim on its text. Other state systems do publish hard non-resident limits; nothing in the sources above says New York does.

Our broader work on the in-state advantage myth argues that the residency advantage families expect at publics usually lives in yield, not in the admissions decision. UB is about as clean an instance as the data gets: no policy lever, no quota, and in two of three years not even an admit-rate penalty. Just a pool of out-of-state admits who go somewhere else. For contrast, UB's Fall 2025 transfer applicants were admitted at 65.45% (3,052 of 4,663) and enrolled at 48.92%, more than three times the first-year in-state yield.

Two Things in UB's Own Filings That Don't Line Up

First, the waitlist. UB's 2024-2025 filing, in a block headed for Fall 2024 admissions, reports 4,267 waitlist offers, 1,785 accepted, and 706 admitted from the waitlist — the same three numbers the 2023-2024 filing reports for Fall 2023. We are not reporting them as two separate years, because the record cannot support that. Treat the pair as one figure of uncertain vintage; UB publishes no other waitlist series that would settle which year it belongs to. The Fall 2025 block is distinct and usable: 2,355 offered a spot, 857 accepted, 106 admitted.

Second, a one- and two-applicant mismatch: in the Fall 2024 and Fall 2023 filings, the residency table's totals differ from the sex table's. Each residency table's rows sum exactly to its own stated total, and those are the totals used here.

What UB Doesn't Publish

UB runs no Early Decision plan — its Common Data Set answers "No" in all three filings we examined, so there is no UB ED acceptance rate to find and any figure presented as one is wrong. UB does offer non-binding, non-restrictive Early Action, closing November 1 with notification on an ongoing basis, but the Common Data Set template collects no Early Action counts and we found none elsewhere on buffalo.edu. There is no round-by-round decomposition either.

There is also no admit rate by school, college, or major: Section C carries only sex and residency, and UB's Factbook admissions dashboard covers higher-education history, gender, and level — not academic unit, residency, or round. There is no campus-level breakdown either, since UB's North, South, and Downtown campuses are one admitting institution with one first-year application. The waitlist is reported only as totals, and the residency series does not run further back than Fall 2023 in the filings we opened.

What This Means for Your Application

If you are applying from outside New York, the admit rate is not your obstacle: seven in ten out-of-state applicants were admitted in Fall 2025, closer to eight in ten in Fall 2024. What the data should change is where UB sits on your list. A school that enrolls 5.66% of its out-of-state admits is functioning, for most of them, as a backup rather than a destination — a reasonable role, as long as the rest of your list is built knowing it. If you are a New York resident, the 80.09% rate is the most straightforward number here.

Our free college list builder will put UB's verified numbers next to the other publics you are weighing, so you can see which are genuinely likely admits and which only look that way. Since UB offers Early Action but publishes no admit data for it, our application deadline tracker is the better way to hold the November 1 Early Action date and UB's regular deadline side by side. And a free strategy call is a good next step if you want help placing UB on your list.
