This document summarizes a workshop on opportunity mapping presented by researchers from the Kirwan Institute. The workshop consisted of three parts: an introduction, a discussion of opportunity mapping and advocacy, and a look toward the future of democratizing data. In the introduction, the presenters provided background on the Kirwan Institute and discussed why mapping is an effective tool for advocacy. They then explained what opportunity mapping is, how it can be used to identify inequities, and potential outcomes of the approach. Finally, they discussed making opportunity maps interactive and accessible online to further their use. The overall workshop aimed to demonstrate how mapping can tell stories about spatial inequities and support advocacy efforts.
