Gendered hiring and attrition on the path to parity for academic faculty

Despite long-running efforts to increase gender diversity among tenured and tenure track faculty in the U.S., women remain underrepresented in most academic fields, sometimes dramatically so. Here we quantify the relative importance of faculty hiring and faculty attrition for both past and future faculty gender diversity using comprehensive data on the training and employment of 268,769 tenured and tenure-track faculty rostered at 12,112 U.S. PhD-granting departments, spanning 111 academic fields between 2011-2020. Over this time, we find that hiring had a far greater impact on womens representation among faculty than attrition in the majority (90.1%) of academic fields, even as academia loses a higher share of women faculty relative to men at every career stage. Finally, we model the impact of five specific policy interventions on womens representation, and project that eliminating attrition differences between women and men only leads to a marginal increase in womens overall representation--in most fields, successful interventions will need to make substantial and sustained changes to hiring in order to reach gender parity.
