Women are earning more PhDs than men. According to a piece by Daniel de Vise in the Washington Post:
The number of women at every level of academia has been rising for decades. Women now hold a nearly 3-to-2 majority in undergraduate and graduate education. Doctoral study was the last holdout – the only remaining area of higher education that still had an enduring male majority.
Of the doctoral degrees awarded in the 2008-09 academic year, 28,962 went to women and 28,469 to men, according to an annual enrollment report from the Council of Graduate Schools, based in Washington.
Men and women appear to earn different types of PhDs, however. According to the article, most of the gains women made in PhD achievement were in health sciences, education, and social and behavioral studies. Men still earn almost 80 percent of engineering doctorates and more than 70 percent of doctorates in mathematics and computer science.
