THE NATIONAL ACADEMIES

National Academy of Sciences

National Academy of Engineering

Institute of Medicine

National Research Council

The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M.Alberts is president of the National Academy of Sciences.

The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering.

The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I.Shine is president of the Institute of Medicine.

The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M.Alberts and Dr. Wm. A.Wulf are chairman and vice chairman, respectively, of the National Research Council.

Preface and Acknowledgments

Issues of gender differences in science and engineering careers continue to merit discussion. In many fields of science and engineering, especially in the life and social sciences, the number of women receiving bachelor’s degrees equals or exceeds the number of men. Yet it continues to be the case that women are underrepresented as professors and elsewhere in the upper echelons of science and engineering. Outside the life and social sciences, the proportions of women shrink, being smallest in engineering. A careful statistical study of these differences has not been conducted for almost twenty years, and many barriers to women in science and engineering have been lowered in that time. This study documents the changes that have occurred, both in the representation of women in science and engineering and in the characteristics of women scientists and engineers.

This report is the result of the labor of many hands in addition to the deliberations of the panel. The tireless efforts of Jim Voytuk were greatly appreciated. Charlotte Kuh served as a member of the Panel until she moved to the National Research Council. Her efforts, both administrative and substantive, were critical to the successful completion of this report. Early drafts were improved by the comments of Mary Frank Fox who

served as a consultant to the Panel, and by the comments of Lowell Hargens, Patricia McManus, Sharon Harlan, Ed Hackett and Barbara Reskin. The panel is also grateful to the following members of the NRC staff who helped on this project as it moved from building useful data sets from the raw NSF data to completed analyses: Rink van der Have, Stephane Baldi, and Ramal Moonesinghe. Linda Skidmore served as the initial project officer.

This study would not have been possible without funding from the Andrew W.Mellon Foundation, National Institutes of Health, and the National Research Council.

The report has been reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise, in accordance with procedures approved by the NRC’s Report Review Committee. The purpose of this independent review is to provide candid and critical comments that will assist the institution in making its published reports as sound as possible and to ensure that the report meets institutional standards for objectivity, evidence, and responsiveness to the study charge. The review comments and draft manuscript remain confidential to protect the integrity of the deliberative process. We wish to thank the following individuals for their review of this report: Margaret Burbidge, University of California, San Diego; Uma Chowdhry, DuPont; Jonathan Cole, Columbia University; Daniel Hamermesh, University of Texas, Austin; Derek Neal, University of Wisconsin, Madison, and Gerhard Sonnert, Harvard University.

Although the reviewers listed above have provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations, nor did they see the final draft of the report before its release. The review of this report was overseen by Judith Liebman, University of Illinois Champaign. Appointed by the National Research Council, she was responsible for making certain that the independent examination of this report was carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of this report rest entirely with the authoring committee and the institution.

Finally, the panel would like to dedicate this report to the memory of Mary Ellen Jones, Betty Vetter and Robert McGinnis. Mary Ellen served as a helpful member of the Panel until her death. Betty’s tireless work with the Scientific Manpower Commission (later renamed the Commission on Professionals in Science and Technology) kept a constant statistical eye on the status of women in science and engineering. Robert McGinnis was a pioneer in the sociology of science and scientific careers and an inspiration for scholars in the field.

Although women have made important inroads in science and engineering since the early 1970s, their progress in these fields has stalled over the past several years. This study looks at women in science and engineering careers in the 1970s and 1980s, documenting differences in career outcomes between men and women and between women of different races and ethnic backgrounds.

The panel presents what is known about the following questions and explores their policy implications: In what sectors are female Ph.D.s employed? What salary disparities exist between men and women in these fields? How is marital status associated with career attainment? Does it help a career to have a postdoctoral appointment? How well are female scientists and engineers represented in management?

Within the broader context of education and the labor market, the book provides detailed comparisons between men and women Ph.D.s in a number of measures: financial support for education, academic rank achieved, salary, and others. The study covers engineering; the mathematical, physical, life, and social and behavioral sciences; medical school faculty; and recipients of National Institutes of Health grants.

Findings and recommendations in this volume will be of interest to practitioners, faculty, and students in science and engineering as well as education administrators, employers, and researchers in these fields.
