* For the purposes of the Humanities Indicators, a faculty member is defined as an employee of a two-year or four-year college or a university who teaches credit-earning courses and who may also perform research activities. Faculty thus include not only individuals who have faculty status in their institutions but also those who are classified as instructional staff by their employers. Faculty exclude those individuals whose duties are purely research-oriented (even though such individuals may be classified as faculty by their institutions).
** Includes the agricultural sciences.
