This document provides an overview of a class presentation given by Samir Gambhir of the Kirwan Institute for the Study of Race and Ethnicity. The presentation discusses how maps can be used to effectively convey information about issues of equity and social justice. Specifically, maps allow for overlaying multiple data points, telling stories through spatial context, and engaging stakeholders through a visual format. Examples are given of how maps have been used to analyze opportunities for minority-owned businesses, hospital investments relative to minority neighborhoods, and targeting areas for advocacy around policies like the Earned Income Tax Credit.
