This report presents a summary of the 1989-90 results of the Survey of Earned Doctorates conducted each year since 1958. Organized into three sections, the report first presents an analysis of trends in the numbers of doctorate recipients including data with regard to fields, gender, citizenship status, time-to-degree, and post-graduation plans (status, postdoctoral location and plans, employment sector). A second section on financial support examines primary sources of support and indebtedness. The final section discusses trends among United States citizen minority doctorates including trends in numbers and proportions of doctorates, doctoral fields, gender, parents' education, degree-granting institutions, primary sources of support, indebtedness, time-to-degree, post-graduation plans, and a summary and tables. Data on five groups are reported: Asians, blacks, Hispanics, Native Americans, and whites. Minorities earned 9.4 percent of doctorates in 1990 and in 1975 they earned 6.3 percent. The most significant gains were among Asians, Native Americans, and Hispanics. Blacks experienced a 17 percent decrease in doctoral degrees received between 1975 and 1990. Four appendixes present basic tables, trend tables for 1980 through 1990, technical notes and the survey instrument. (JB)
