Abstract

Although wealth concentration and large fortunes have attracted increased scholarly attention in recent decades, this work has been largely gender-blind. This study examines changes in the gender composition of global billionaires over the last 14 years (Forbes world’s billionaires list, 2010 – 2023) and asks how male and female billionaires differ in their likelihood to perpetuate their billionaire status. Between 2010 and 2023, we find a modest increase in the percentage share of female billionaires, from 9.0 to 12.8 percent. While the share of female self-made billionaires more than doubled, the share of female billionaire heirs increased only by 43 percent during the observed period, highlighting the importance to differentiate between the source of billionaires’ wealth when studying gender differences. To examine differences in the long-term perpetuation of billionaire fortunes by gender and source of wealth of billionaires, we apply survival analyses. We find that men stay on the Forbes list significantly longer than women. Overall, this study contributes to the literature on gender wealth inequalities by showing how billionaires’ wealth is structured by gender.
