This book is designed to provide current and historical statistics about the professional segment of the population and particularly the participation and availability of women and minorities. Over 200 data sources were used to prepare the statistical tables and charts. The first five chapters focus on general enrollments, general degrees, general professions, general workforce, and academic workforce; they include both tables which do not specify subject fields and tables where several subject fields are included. In the section on general professions, data for individual professions follow tables that include data for multiple fields. Tables in chapters 6 through 10 provide data on degrees, enrollments. and workforce by subject field: physical, mathematical, and computer sciences; engineering, technology, and technicians; agricultural, biological, medical, and health sciences; social and behavioral sciences; and arts, humanities, and education. Fairly major differences were found between the proportions of degrees granted to women and minorities in any particular field and the proportions of those persons found in the workforce for that field. A bibliography, data sources, and recruitment sources are identified, and an index is included. (MNS)
