Data has the capacity to illustrate the lived experiences in and of communities, transforming anecdotal evidence into actionable knowledge. This introduction to advocating with community data introduced participants to the fundamentals of community data collection, organization, and visualizing. Participants compiled and generated a dataset, and built a website that models how one might access, analyze, map and use data to inform decision-making. In addition, participants discussed advocacy, community engagement, and crowdsourcing towards developing techniques for equitable partnerships with community partners. This workshop involved hands-on experience with spreadsheets, Jekyll, and Leaflet.
