Urbanization processes and outcomes that exclude racialized or ethnic-minority residents create deeply unjust landscapes because the majority population—often white or of European origin—are in a position to disproportionately shape and reap the benefits of access to a range of urban amenities and opportunities. In this chapter, we consider the deep roots of these processes and discuss what urban sustainability and justice outcomes are when people’s racialized realities are, and are not, taken into account. We analyze these dynamics through two core issues: (i) racial and ethnic segregation and (ii) white privilege. In closing, we provide some examples of existing policy approaches and grassroots revindications that seek to redress the impacts of racialized or ethnically exclusionary urbanization processes.
