This report investigates the effects of diversity on governance by examining the supply and demand for minorities trained in public policy analysis and management and international affairs specialties at the federal level. The data were obtained from various U.S. Government published reports. Topics covered concerning the supply side include: college participation rates; enrollment trends in graduate professional programs in public policy and international affairs analysis and management; and diversity initiatives in higher education. Among topics covered concerning the demand side are: foundation support for public policy and international affairs; federal programs in international affairs; diversity in the federal civilian workforce; diversity at the professional level; trends in achieving equal employment opportunity; minority recruitment; diversity and international affairs; diversity in management intern programs, and diversity within a variety of specific U.S. Government departments and agencies. The difficulty of achieving diversity is addressed in sections on the scope and findings of key federal studies; successful strategies in promoting diversity; and the need for diversity at the Cabinet level. The final section evaluates the outlook to the year 2000. The appendix contains numerous charts and tables detailing findings on these issues. (Contains 81 endnotes and a bibliography of 21 references.) (JB)
