GIS & Health with Rex Dwamena & Johnnie 'Chip' Allen: Turning Public-Health Data into Action
Let us know what you thought of this episode. Where people live can profoundly influence their access to care, exposure to risk, and overall health outcomes. In this episode, Rexford Dwamena explains how GIS helps public-health professionals look beyond countywide averages to uncover disparities at the neighborhood level. Joined by Erica Phillips and Johnnie “Chip” Allen, Rex discusses the development and application of the Health Opportunity Index, the role of spatial analysis in directing limited resources, and why maps must lead to meaningful policies and interventions—not simply display data.
