Enrollment trend & projection

Total enrollment went from 774 in 2018 to 1,254 in 2022 — over 4 years.
+62.0%
Why only 2 data points?

Private school enrollment comes from the NCES Private School Universe Survey (PSS), which is collected every other year — not annually like public-school data. The most recent published collection is 2021–22; NCES targeted spring 2026 for the 2023–24 release — we'll load it as soon as it's published.

For a more current snapshot, see The Greenwich Country Day School's own published school profile (as of 2024-25): www.gcds.net/admissions/school-profile ↗
