Why So Few?: Women in Science, Technology, Engineering, and Mathematics
The number of women in science and engineering is growing, yet men continue to outnumber women, especially at the upper levels of these professions. In elementary, middle, and high school, girls and boys take math and science courses in roughly equal numbers, and about as many girls as boys leave high school prepared to pursue science and engineering majors in college. Yet fewer women than men pursue these majors. Among first-year college students, women are much less likely than men to say that they intend to major in science, technology, engineering, or math (STEM). By graduation, men outnumber women in nearly every science and engineering field, and in some, such as physics, engineering, and computer science, the difference is dramatic, with women earning only 20 percent of bachelor’s degrees. Women’s representation in science and engineering declines further at the graduate level and yet again in the transition to the workplace.
Drawing on a large and diverse body of research, this report presents eight recent research findings that provide evidence that social and environmental factors contribute to the under-representation of women in science and engineering. The rapid increase in the number of girls achieving very high scores on mathematics tests once thought to measure innate ability suggests that cultural factors are at work. Thirty years ago there were 13 boys for every girl who scored above 700 on the SAT math exam at age 13; today that ratio has shrunk to about 3:1. This increase in the number of girls identified as “mathematically gifted” suggests that education can and does make a difference at the highest levels of mathematical achievement. While biological gender differences, yet to be well understood, may play a role, they clearly are not the whole story.
