The contraceptive pill is widely recognised for its profound social impact, but its economic consequences were equally transformative. Developed at the urging of birth control activist Margaret Sanger, the pill aimed to liberate women sexually and socially. However, it also triggered what may be the most significant economic shift of the late 20th century.
The pill's effectiveness was a key factor. With a typical-use failure rate of just 6%, it was three times safer than condoms. Used perfectly, the failure rate dropped to 0.3%. Unlike other methods, the pill gave women private, discreet control over their fertility without requiring negotiation with a partner.
Approved in the US in 1960, the pill was quickly adopted by married women. But the real revolution began around 1970, when US states started making it easier for single women to access oral contraceptives. Universities opened family planning centres, and by the mid-1970s, the pill was the most popular form of contraception for 18- and 19-year-old women.
This newfound control over fertility allowed women to invest in long-term careers. Before the pill, pursuing a professional degree—such as medicine, law, or dentistry—was risky, as an unplanned pregnancy could derail years of study. With the pill, women could reliably delay motherhood and commit to demanding courses. In 1970, over 90% of medical and law degrees were held by men, but by 1980, women often made up a third of these classes.
The pill also changed marriage dynamics. Before its widespread availability, women married young to secure a partner. The pill allowed women to delay marriage and focus on their careers while still having a social and sexual life. This shift contributed to a surge in women entering professional fields, fundamentally altering the workforce and the economy.
