When you drive down Stewart Street or walk across the leafy campus in southwest Ohio, it’s easy to think you’ve got the University of Dayton student population figured out. It looks like your classic, mid-sized Midwestern school. But honestly, the numbers tell a much more interesting story than just a sea of red and blue jerseys on a Saturday afternoon.
The student body isn't just one big monolithic group. It’s actually a pretty complex mix of undergraduates chasing that famous "UD porch life" and graduate researchers working on high-level aerospace tech. For the 2024-2025 academic year, the total headcount sits right around 10,506 students.
Wait, is that big? Small? Basically, it’s the "Goldilocks" of campus sizes. You aren't just a number in a massive lecture hall, but you also won't know every single person you pass on the way to the Kennedy Union.
Breaking Down the Numbers: Undergrads vs. Grads
If you're looking at the raw data, the undergraduate crowd is definitely the heart of the operation. About 7,740 students are pursuing their first degree here. These are the folks living in the Ghetto—that's what they actually call the student neighborhood, and it’s a point of pride, not a slur—and filling up the stands at UD Arena.
On the flip side, the graduate and law student population is surprisingly robust. There are 2,766 graduate students currently enrolled. What's wild is that while undergraduate numbers have dipped slightly over the last decade (down about 900 since 2015), the graduate side has actually been growing. People are coming here for the serious stuff: engineering, business, and specialized doctoral programs.
The gender split is almost a perfect mirror image.
- Men: 5,477 (52%)
- Women: 5,029 (48%)
It’s one of those rare campuses where you don't feel a lopsided energy one way or the other. It feels balanced. Sorta rare for a school with such a heavy engineering lean, right?

The Diversity Question
Let's be real for a second. If you look at the stats, UD has historically been a very white institution. About 70.5% of the students identify as White. For a long time, that was the narrative—that it lacked a certain "cultural grit."
But the needle is moving. Slowly, but it's moving.
Currently, the racial breakdown looks something like this:
- Hispanic/Latino: 617 students (roughly 6%)
- Black or African American: 585 students (around 5.6%)
- Two or More Races: 347 students
- Asian: 186 students
It’s not just about race, though. The University of Dayton student population is surprisingly "un-local." Only about 54% of students are from Ohio. The rest are coming in from places like Chicago, St. Louis, and the East Coast.
And then there's the international crowd. You’ve got nearly 1,000 international students from over 30 different countries. The biggest groups? Usually from China, India, and Kuwait. You’ll hear a dozen different languages while waiting in line for a bagel, which definitely kills that "small town" vibe people expect.
Where Everyone Lives (and Why it Matters)
You can't talk about the student population without talking about the housing. It defines the culture.

Most schools have dorms. UD has a neighborhood.
About 90% of undergraduates live on campus or in university-owned housing. This is huge. It means the student population doesn't just vanish at 5:00 PM. They stay. They hang out on those iconic porches. They build a community that feels more like a small village than a school.
Age Distribution: Not Just 19-Year-Olds
While the vast majority (about 8,773) are under 25, there is a significant "adult learner" presence.
- Traditional Age (18-21): The bulk of the undergrads.
- Young Professionals (22-29): Mostly the law and masters students.
- Returning Learners (30-50+): Often folks in the online programs or continuing education.
Actually, the online population has exploded lately. We're talking a 75% increase in online-only students since 2015. Nowadays, about 729 students never even step foot on the Dayton campus. They're part of the population, just... virtually.
The Academic Vibe
Why are these 10,000+ people here? It’s not just for the basketball games (though those are legendary). The student-to-faculty ratio is 14:1.
That’s a fancy way of saying your professors actually know your name. You aren't being taught by a nameless TA in a 500-person auditorium. This affects the "type" of student UD attracts: people who want to be mentored, not just lectured.

The most popular majors currently driving the population are:
- Mechanical Engineering (The big kahuna at UD)
- Finance
- Marketing
- Computer Science
What’s Changing in 2026?
The university isn't just sitting still. They’ve been trimming some underperforming graduate programs lately to "right-size" the ship. Casey Gill, the VP of student development, has been pretty vocal about maintaining an "optimally sized" undergraduate population.
They don't want to be a 30,000-student behemoth. They like being mid-sized. It's their identity.
They're also making it easier to transfer in. If you're a community college student or looking to switch schools, UD has recently loosened up their credit transfer rules to keep the enrollment numbers steady.
Actionable Insights for Prospective Students
If you're thinking about becoming a part of the University of Dayton student population, here’s what you actually need to do:
- Visit on a Tuesday: Don't just go for a Saturday game. Walk around on a weekday to see the actual "commuter-less" culture in action.
- Look past the surface: If you’re a minority student, reach out to the Multi-Ethnic Education and Engagement Center (MEC). The numbers are growing, but the support systems are what make the difference.
- Check the "Ghetto" availability: If you’re a transfer, ask specifically about university-owned houses. Living in a house with friends is the "core" UD experience that most students cite as their favorite part.
- Research the "Flyer Promise": If the cost is a barrier, look into this program. It’s designed specifically to diversify the population by helping students from underrepresented backgrounds afford the private school tuition.
The University of Dayton is in a weirdly cool spot right now. It's big enough to have "Top 100" research facilities but small enough that you'll still get a "Happy Birthday" text from your advisor. It’s a population that is slowly becoming more global, more digital, and more diverse, while desperately clinging to those old-school neighborhood traditions.
