American Society for Rickettsiology · Annual Meetings 2022–2025
ASR by the Numbers
Who comes to the ASR Annual Meeting, where they work, and how the program has grown. Every figure is a total, never a person.
Attendance
A steady meeting of 128–168 scientists, and almost half are trainees
Registrants per meeting, split into trainees and everyone else. Staff, social guests and canceled registrations are left out.
Bars are drawn to one scale (168 = full width). Percentages are the trainee share. 2026 was the joint ESCCAR meeting in Logroño, Spain, run by its own organizers, so it is not included.
