Womenâs participation in the work force increased gradually through most of the 20th century, then rose more rapidly from the early 1970s through the early 1990s. About one-third of working-age women held jobs outside the home in the years after World War II. By the early 1990s, about three-quarters of those women worked.
Since then, however, the trend has stagnated. The proportion of women ages 25 to 54 either working or looking for work stood at 75 percent in April.
That remains more than 10 percentage points lower than the figure for men in the same age range working or seeking work, which was 88.6 percent in April.
Ms. Yellenâs speech was unusually narrative and unusually personal. Speaking at her alma mater, she told the stories of other women who graduated from Brown, including her husbandâs aunt, Elizabeth Stafford Hirschfelder. She said Ms. Hirschfelder, who graduated in 1923, faced discrimination throughout her career as a mathematician. âI believe that Betty Stafford Hirschfelder was denied opportunities and greater success simply because she was a woman,â she said.
Ms. Yellen, who is 70, said women of her own generation had faced fewer obstacles and had more opportunities. âI enrolled at Brown fully planning to attend graduate school and have a career, as did many of my classmates in the Class of 1967,â she said. She noted that changes in policy supported and reinforced changes in society. A 1974 law, for example, allowed women to apply for loans without a male co-signer.
Women gained entry into a wider range of professions, and the gap between menâs and womenâs wages narrowed significantly. Nancy H. Teeters became the first woman appointed to the Fedâs board in September 1978. Ms. Yellen said that their increased work force participation had produced clear benefits not only for women, but also for men, for the children of working women and for the American economy.
âThe evidence shows that the rise in womenâs participation has contributed to widespread improvements in the safety and productivity of our workplaces, to the health of families and to the macroeconomic success that our country has enjoyed,â she said. She spoke at a conference titled â125 Years of Women at Brown.â
That progress, however, has stalled in the United States even as the participation of women in the work force has continued to rise in other developed countries. The United States, which had one of the highest rates of participation in the early 1990s, fell to 17th among 22 developed nations in one recent analysis.
That analysis, a 2013 study by Francine D. Blau and Lawrence M. Kahn, both of Cornell University, attributed much of the difference to government policies. The United States lags behind other countries in the availability of paid maternity leave, affordable child care and flexible work schedules. Ms. Blau and Mr. Kahn estimated that adopting European policies on those issues could close more than half of the gap in the United States between male and female labor force participation.
Ms. Yellen also cited research showing that women still make about 10 percent less, on average, than men with similar backgrounds who work in similar positions.
