Admissions (Class of 2029 / Fall 2025)

Women: 50.7%, Asian: 12.6%, Black: 5.1%, Hispanic: 7.9%, White: 34.7%, International: 30.2%

381 varsity athletes (~11.3% of undergrads — highest among Ivies). NCAA Division I, Ivy League Conference.

Located in NYC. No officially published ED rate. Highest international enrollment among Ivies (30.2%). Strong pre-professional culture.

ED acceptance rate ~16.7% vs ~2.8% RD — one of the largest early/RD gaps among Ivies (ED multiplier ~3.4x per Class of 2029 data)
Yield protection is widely discussed on forums — Columbia is believed to use predictive models considering how many schools applicants applied to and level of demonstrated interest
Forum advice: ED is "basically required" for non-hooked applicants; the RD rate is so low (~2.8%) that RD admission without hooks is considered near-impossible
ED pool is loaded with recruited athletes who had prior coach contact — the "real" non-athlete ED rate may be lower than the published 16.7%
Highest international enrollment among Ivies (30.2%) — forums note Columbia is popular with international applicants drawn to NYC

NYC location is the defining feature — praised for professional opportunities but criticized for lack of traditional campus cohesion
Core Curriculum is rigorous and polarizing — students either love the shared intellectual experience or find it burdensome
Strong pre-professional culture, especially for finance and consulting
Forums describe social life as more fragmented than other Ivies due to NYC distractions
Post-2022 rankings controversy (US News methodology objections) created lasting reputation concerns on forums

Need-blind for domestic applicants; recently expanded to need-blind for international
Net costs are slightly higher than Harvard/Princeton at lower income brackets (~$10K vs ~$4K for families under $30K)
Forum consensus: generous but not best-in-class — some complaints about expected family contribution calculations

ED multiplier of ~3.4x is among the highest — model should strongly reward ED applicants
65% yield is relatively low for an Ivy — Columbia loses many admits to HYPSM; yield model should reflect this
Yield protection behavior means strong-but-uncommitted applicants may be waitlisted in RD — consider modeling this
High international student share (30%) affects demographic composition and yield patterns
