The National Science Foundation’s Survey of Earned Doctorates (SED) began in 1957-58 to collect data continuously on the number and characteristics of individuals receiving research doctoral degrees from all accredited U.S. institutions. This includes discipline specific data on degrees awarded in the field of Linguistics. Information from this survey becomes part of the Doctorate Records File (DRF). The DRF contains data on all earned doctorates granted by U.S. universities, in all fields from 1920 to the present. The results of this annual survey are used to assess characteristics and trends in doctorate education and degrees. This information is vital for educational and labor force planners within the federal government and in academia.

The NSF is testing the SED Tabulation Engine, a pilot tool allowing users access to selected variables from the Survey of Earned Docturates.
