Against a design intent of 400 students and 70 faculty, today's GSD runs at roughly twice and three times those numbers. The school has more than tripled its teaching corps relative to the original plan while enrollment only doubled. While the GSD has added square footage to its total footprint by acquiring additional buildings, the fact is that most academic energy is still concentrated in the main building. Furthermore, there's a case to be made that this expansion has only exacerbated budgetary constraints.
Being oversized is not only a matter of crowding; it is a structural cost problem. Each student costs the school about $87,000 a year to educate but pays about $39,000 in net tuition, so every seat is subsidized roughly $48,000 from the endowment and gifts.
Adding students widens that gap rather than closing it. From AY15‑16 to AY24‑25 expenses and revenue have grown nearly in lockstep, at about 3.4% a year. Where has this additional revenue come from? Over the past decade almost all of the GSD's revenue growth came from just two sources, net tuition and the endowment draw, about $11M each; gifts and sponsored research actually shrank.
Critically, tuition did not grow because of enrolling additional students. It was price: net tuition per student rose about 3.5% a year, well ahead of inflation.
With this in mind, holding the population steady is not an option either: if the GSD stays at its AY24‑25 population of 888 students while expenses continue to inflate at 3-4% a year, the budget will either slip into deficit within a few years or tuition will have to keep rising, putting it even further out of reach of many students. Hold tuition affordable and the school runs deficits; raise it to keep pace and it prices people out.
We already see this squeeze playing out in the data over the past decade, with the school paying for its overgrowth by making each seat steadily more expensive. The problem is therefore the structure of the institution, the ratio of people to resources, not the pace of growth, and shrinking is the one move that raises resources per student instead of chasing costs.
