Headcounts are as of November 1 each year. Weill Cornell Medicine is excluded.
To reflect new definitions of University Faculty and RTE Faculty, headcounts prior to 2022 have been restated in this December 2022 presentation. To review previously published numbers, see our Factbook Archives.
The University Faculty is established by Article XIII of the University Bylaws and includes those with the title of Professor, Associate Professor, Assistant Professor, University Professor and Professor-at-Large. Faculty are counted within the college of tenure or primary academic appointment.
The Research-Teaching-Extension (RTE) Faculty include those with the following titles: Professor-of-the-Practice (all ranks), Clinical Professor (all ranks), Research Professor (all ranks), Librarian (all ranks), Archivist (all ranks), Lecturer, Senior Lecture, Research Associate, Senior Research Associate, Extension Associate, Senior Extension Associate, Instructor, Teaching Associate, Senior Scholar, Senior Scientist, Research Scientist and Principal Research Scientist.
The headcounts above exclude all adjunct, acting, visiting, courtesy and emeritus appointments as well as postdocs, interns, residents and other temporary titles and casual employees. Staff and union employees on leave are omitted, but academics on leave are included. Staff and union employees with no salary or who work less than 20 hours per week are omitted. Student employees are omitted.
In cases where employees have more than one job, only the primary job/appointment is presented.
