Fig.4 - Female Physicians in Workforce (%)
STEM professions, like medicine, require higher education or training in nearly all cases. Since the feminist revolution of the 1970s, the opportunities available to men and women in higher education have become broadly similar in most advanced economies. In some countries, such as the United States, 33% more bachelor's degrees are conferred on women than men. This has not yet translated to equal representation for women in all STEM professions.
