Significance The US workplace is hypersegregated into two worlds, a “men’s world” comprising occupations with very few women, and a “women’s world” comprising occupations with very few men. Although many commentators have argued that this gender divide would gradually wither away, in fact the workplace suddenly stopped integrating 20 y ago. By building a model that combines mobility and segregation processes, we show that the stall was partly driven by a change in how fathers transmit occupations. When daughters streamed into the economy, fathers began to pass on male-typed occupations disproportionately to their sons, whereas mothers remained steadfastly gender-neutral. This son-biased shift, which cut off the integrative trend, suggests a role for family-centered interventions that target where the gender revolution faltered.
