What is the relationship between design, power, and social justice? "Design justice" is an approach to design that is led by marginalized communities and that aims explicitly to challenge, rather than reproduce, structural inequalities. It has emerged from a growing community of designers in various fields who work closely with social movements and community-based organizations around the world.This book explores the theory and practice of design justice, demonstrates how universalist design principles and practices erase certain groups of people-specifically, those who are intersectionally disadvantaged or multiply burdened under the matrix of domination (white supremacist heteropatriarchy, ableism, capitalism, and settler colonialism)-and invites listeners to "build a better world, a world where many worlds fit; linked worlds of collective liberation and ecological sustainability.
