This working paper series presents preliminary results from the Gender and Everyday Water Use in Los Angeles Study. Conducted by researchers at the UCLA Center for the Study of Women with the support of a Sustainable LA Grand Challenge Grant, this project investigates the important but understudied role of gender—as it intersects with race and class—in residential water use in Los Angeles. The goal of reducing residential water use requires nuanced understanding the ways that people use, think about, and value water. In the context of international development, policymakers and researchers understand that gender shapes water, especially because women and children are disproportionately responsible for procuring water. In the United States, feminist scholars long have found that divisions of labor and decision-making are often gendered. Putting together these two bodies of knowledge, along with the fact that women have led many American water struggles, from Standing Rock to Flint to Compton, it is surprising that gender remains largely absent from water management and water research in the U.S. This study found that women disproportionately are responsible for the household management of water and for its use in households. It connects everyday life to the large-scale questions of water scarcity and management that face our world in the twenty-first century.
