As sexual and reproductive repression increases around the world, engaging with reproductive politics has become acutely urgent. This reproductive repression exists alongside pervasive economic precarity, untenable costs of living, and pressing demands for higher labor productivity. What feels like the emergence of a novel reproductive and economic dystopia, however, is a long-lasting reality for poor Black women globally. Comparing Senegal and North Carolina, T.D. Harper-Shipman shows how states and markets turn to poor Black women's fertility to assuage economic and social crises that would otherwise expose the failings of modern political economy. Moving through formative moments that draw reproductive health, gender, race, and labor into closer proximity—from the transatlantic slave trade through to the present—Harper-Shipman argues that reproductive health policies are instruments for national and international elites to regulate resource distribution and recreate future stores of differentiated labor across time and space.   Unruly Fertility attends to the innovative and unconventional forms of resistance that poor Black women use to decouple their productive and reproductive labor from state efforts to manage their fertility. These discreet forms of resistance establish new possibilities that scaffold decolonial reproductive politics. Harper-Shipman compels us to view reproductive politics as an enduring battle over which bodies deserve the fruits of modernity, and which bodies get perpetually marked as the vehicles for carrying all of humanity forward.
