This document summarizes a presentation about structural racialization and opportunity mapping. It discusses how understanding of opportunity has evolved from one-dimensional to multi-dimensional, recognizing the interaction of physical, social, and cultural structures that produce racialized outcomes. It addresses concepts like implicit bias, intergroup relations, and the geography of opportunity. Solutions require recognizing how implicit and explicit biases interact with policies and institutions to maintain racial hierarchies through processes like categorization, inequality, and exploitation. Mapping is presented as a way to show the spatial inequities produced by opportunity segregation and the cumulative effects of structures that mediate different groups' access to resources.
