In the decade since Opportunity Mapping has come onto the scene, The Kirwan Institute for the Study of Race and Ethnicity has employed the methodology in partnership with cities across the country to better understand equity and opportunity. This work has led to policy changes that have made cities and regions more equitable. This presentation will explore the Tacoma Equity Index, an index designed in partnership with the City of Tacoma Office of Equity and Human Rights to inform the creation of policies to create a more just and equitable Tacoma where all people have the opportunity to succeed. This presentation will walk participants through the equity index process, which employs a participatory design approach and focus on how local data can be incorporated into these indexes to achieve a more nuanced understanding of local equity and opportunity priorities. Next, participants will explore the tool and learn firsthand how such a tool can be used to craft equitable policy at the city and neighborhood scale. Presenters will then answer questions from the audience.
