This document summarizes a presentation about using geographic information systems (GIS) and opportunity mapping for research and advocacy at the Kirwan Institute. It provides an overview of the Kirwan Institute's mission and work analyzing spatial trends related to opportunity, such as access to employment, education, healthcare, and more. It then describes the methodology of opportunity mapping, which identifies indicators of opportunity, calculates z-scores to measure relative performance, and develops an overall opportunity index to compare areas and identify gaps. Examples of opportunity maps for various regions are also presented to demonstrate how the technique can be used to analyze issues of inequity.
