III-24a: Median Annual Earnings of Full-Time Workers with a Doctoral Degree, by Gender and Field of Degree, 2015*
* Full-time workers are those who worked 35 or more hours per week for 50 or more weeks during the previous 12 months. Earnings estimates have been rounded to the nearest $1,000. The analysis excludes holders of the D.D.S., D.V.M., M.D., and other non-research degrees.

Since the humanities were dropped from the biennial Survey of Doctorate Recipients (SDR) in 1995, the National Science Foundation’s National Survey of College Graduates (NSCG) is the only source of nationally representative data on the occupations and earnings of humanities Ph.D.’s. Conducted every two years, the NSCG gathers detailed education, occupation, and earnings information from a sample of individuals drawn from the larger pool of all those identified via the American Community Survey (ACS) as holders of a baccalaureate degree. Given the size of the NSCG sample, reliable estimates are available only for broad academic fields. For the NSCG disciplinary categories included in each of the field-of-degree categories employed by the Humanities Indicators, see the provided crosswalk. This earnings indicator is based on NSCG data, but similar items included in the Humanities Indicators rely on data from the ACS. Due to marked differences in how NSCG and the ACS classify academic fields, the contents of the field-of-degree categories used for this indicator are not identical to those used for the ACS-based Indicators III-07a and 07b. (For more information on the contents of the categories used for the ACS analysis, see the pertinent crosswalk.)
Another key difference between these indicators and the ACS-based earnings indicators is that the Ph.D. holders considered here are those whose doctoral degree was in the humanities (irrespective of the field of their undergraduate and any terminal master’s degree). The ACS does not collect data about the field of advanced degrees. The ACS-based indicators thus describe the earnings of undergraduate humanities majors who went on to pursue advanced degrees, regardless of the field of the advanced degree.
