The underrepresentation of women, minorities, and persons with disabilities in most areas of scientific and technical endeavors is an issue of continuing concern to educators, employers, and those organizations responsible for sponsoring research and development activities. Although the number of women graduating with bachelor’s degrees from some scientific fields equals or exceeds the number of men, in many fields there are far fewer women than could be expected from their number in the general population or on college and university campuses (see "Indices of Representation" on page 63). Since 1989, the number of underrepresented minorities earning bachelor’s degrees in science, mathematics, and engineering (SME) has risen each year.
Underrepresented minorities earned over 17 percent of the total number of undergraduate SME degrees awarded in 1995, up from 12 percent in 1989. (See appendix table 3-1.) The continuing differences in the enrollment and graduation rates of different racial/ethnic groups in science, mathematics, and engineering at the undergraduate level need to be better understood.
This chapter examines factors that influence access, achievement, and educational outcomes for women, minorities, and persons with disabilities who attend 2-year and 4-year institutions. This review of undergraduate education looks at changes in enrollment, course-taking patterns, and outcomes over the past few decades at all institutions of higher learning. It examines patterns of courses taken and outcomes (degrees awarded, attrition) by age, race/ethnicity, and major. An examination of these factors provides a greater understanding of the reasons that disparity among groups entering the fields of science, mathematics, and engineering has persisted.
Since 1980, more women than men have enrolled in college, and since 1982, women have earned more undergraduate degrees than have men. In 1995, women constituted 49 percent of the U.S. population ages 18 to 24 and earned 55 percent of all bachelor’s degrees awarded, up from 43 percent in 1966. (See appendix tables 3-2 and 3-3.)
Despite impressive gains, the participation of women in the physical sciences, mathematics, and engineering still lags significantly behind that of white men and Asians, as evidenced by the following:
Women are, however, as well or more highly represented than men in some science fields. For example, they earned nearly half of the bachelor’s degrees awarded in 1995 in the biological/agricultural sciences and social sciences and 73 percent of the degrees in psychology. (See appendix table 3-2.)
Systematic data on minority participation in science, mathematics, and engineering education have been collected only since the late 1970s. (See appendix tables 3-4 and 3-5.) The bulleted data below show disparities persisting over time. Recent studies provide insight into the role that precollege preparation, self-confidence, work and family, availability of role models, peer support, and teaching methods play in maintaining that disparity.

Patterns of overrepresentation and underrepresentation of the racial/ethnic and gender groups were analyzed in more detail. To measure the extent to which the various groups were overrepresented, at parity, or underrepresented in the college population, an index of representation (IR) was computed. (See "Technical Notes to Chapter 3" for details.)
The IR for total college enrollment indicates that in 1980 white males and females, Asian males and females, and American Indian females had higher proportions among persons enrolled in college than they had among the general population of 18- to 24-year-olds. Asian males and females had the highest index scores. (See figure 3-1, text table 3-1, and appendix tables 3-6, 3-7, 3-8, and 3-9.) In 1980, black males and females, Hispanic males and females, and American Indian males were underrepresented in the college population. Hispanic males and black males had the lowest index scores. The IR score for American Indian females in 1980 indicates that their representation in the college population was higher than their representation in the general population.
Between 1980 and 1990, except for white females, persons from all racial/ethnic and gender categories were less represented in the college population than in the general population. After 1990, the representation scores of both white males and females decreased while those of the other categories increased. Racial/ethnic minorities have improved their representation in higher education. Black females had almost achieved parity by 1994. Their IR score in 1994 was essentially equal to that of white males whose proportional representation in the college population has systematically decreased below parity. On the other hand, Asian males and females, white females, and American Indian females continued through the beginning years of the 1990s to be overrepresented in the college population. The rate of improvement among black males has been slower than that of the other groups that improved. Hispanic males have caught up with black males in their proportional representation in the college population.
