In rejecting "Plessy v. Ferguson's" "separate but equal" doctrine in "Brown v. Board of Education," the U.S. Supreme Court created a presumption that segregation equals discrimination. However, alongside this assertion, American space has become increasingly separate. A socio-legal analysis identifies three generations of spatial segregation in the United States and calls for recognizing the fourth generation--separate, therefore equal--in which minority communities require voluntary self- segregation to achieve equality. This fourth generation of spatial separation requires the law to embrace a protective role, by which it will defend the ability of minority communities to segregate spatially, the autonomy of individual community members, and the welfare of the society at large.
