The United States has produced viable female presidential candidates, women athletes who command millions of dollars in endorsements, and the first female Nobel economist. Yet there is still no female equivalent of a Steve Jobs, Bill Gates, or Mark Zuckerberg. Women continue to lag behind men in computer science, where their share of the workforce has actually declined over the past 25 years. Today, women hold 27 percent of all CS jobs, down from 30 percent a decade ago, and account for just 20 percent of undergraduate CS majors, down from 36 percent in 1986.
