University of California, Los Angeles (UCLA)

What UCLA is

The University of California, Los Angeles — UCLA — carries both its university system and its city in its name. Its own fact sheet gives total enrolment as 46,678 students, made up of 33,040 undergraduates and 13,638 graduate students, with 5,464 faculty members ^[2]. Read together, those numbers describe a university whose centre of gravity is undergraduate teaching: roughly seven undergraduates for every two graduate students, and about eight and a half students for each member of the faculty.

Within the whole, the College of Letters and Science is by far the largest unit, with 25,473 undergraduates and 2,991 graduate students ^[2]. That is more than three-quarters of all undergraduates and about a fifth of all graduate students — a reminder that at a university of this shape, most teaching happens in one big liberal-arts college rather than in professional schools.

Who studies there

The composition figures are the most revealing part of the picture. 79.4% of undergraduates are California residents, while only 45.6% of graduate students are ^[2]. Undergraduate education at UCLA is therefore overwhelmingly a service to its own state; graduate education draws far more heavily on the rest of the country and the world.

Other measures describe who gets in and what they bring. 29% of undergraduates are first-generation students — the first in their families to attend university — and 28% receive Pell Grants, the United States federal grants given on the basis of financial need ^[2]. Just over one in four undergraduates is therefore from a lower-income household by that measure. International students make up 7.7% of undergraduates, and the university reports 6,347 international students in all, drawn from 107 countries ^[2].

These are the standard numbers institutions use to describe themselves, and each answers a different question: the residency share says how far a university serves its home state, the first-generation and Pell shares say how open it is to students whose parents did not go to university or who need aid, and the international share says how far the campus reaches beyond the country. UCLA's profile is a very large undergraduate population, mostly from California, with a substantial minority of first-generation and lower-income students and a comparatively small international undergraduate presence.

A link to AI research

One thread connects UCLA to the story of artificial intelligence. Song-Chun Zhu joined UCLA in 2002 and worked there as a computer vision researcher before returning to China ^[1]. Computer vision is the branch of AI concerned with getting machines to interpret images and video, and it is one of the fields where large universities with big graduate programmes have trained many of the researchers who later built AI systems.

How to read these figures

Enrolment numbers of this kind are snapshots, reported by the institution itself and revised from year to year as admissions cycles and funding change. They are useful not because any single figure is permanent but because they show the shape of an institution: how many people it teaches, at what levels, and where those people come from. For anyone trying to understand how a very large university is organised — and how its undergraduate college, its graduate programmes and its research staff fit together — this is the ground floor of the picture.
