USAMO and USAJMO 2026 Results Analysis

This article extracts practical insights from the newly published USAMO and USAJMO 2026 results and shows how to reproduce the same views on MathIntegrity.org.

MathIntegrity mirrors official MAA-published winner lists into a searchable dataset, so coaches, students, and parents can quickly analyze state and gender patterns.

In this article, we use three concrete examples to demonstrate the workflow:

1. Which states provide the most USAMO and USAJMO students
2. Gender distribution among USAMO students
3. Gender distribution among USAJMO students

It also includes a step-by-step workflow for using MathIntegrity.org to view distributions and inspect student trajectories.

For score-distribution context and historical perspective, see Evan Chen’s write-up: USAMO statistics.

Data Source and Important Disclaimer

• Official upstream source: MAA Student Awards page for USA(J)MO winners (MAA Youth Program Awards Winners).
• MathIntegrity source tables (structured copy for search and analysis): database/contests/amo/year=2026/results.csv and database/contests/jmo/year=2026/results.csv.
• State counting method: state is taken from database/students/students.csv (joined by student_id), not from the contest CSV state field.
• Coverage limitation: this dataset contains published USA(J)MO awardees/winners, not the full competitor or qualifier pool.
• Gender source: database/students/students.csv (gender field).
• Gender values come from the student profile table and may be corrected over time as records are updated.
