This report presents data on the demographic and employment characteristics of the nation's doctoral scientists and engineers. Data were developed as part of the Longitudinal Doctorate Project. Current information on the supply and utilization of doctoral personnel in science and engineering reflects the results of the 1997 Survey of Doctorate Recipients (SDR), the 13th in a biennial series. The population of the 1997 survey included persons under the age of 76 who hold doctorates in science or engineering from U.S. institutions. This report provides information on the number of scientists and engineers by demographic characteristics such as citizenship, place of birth, field of degree; and employment-related characteristics such as occupation, sector of employment, median salary, and various labor force rates. Some tables in this report include estimates for doctoral scientists and engineers employed in four-year colleges and universities. Detailed statistical tables, technical notes, and the survey instrument are also included. The Technical Notes section contains information on survey methodology, coverage, concepts, definitions, and sampling errors. (WRM)
