Insights
Learn about the OEPS, code resources, and research insights .
The OEPS data ecosystem was designed to support research seeking to study environments impacting and impacted by opioid use and opioid use disorder (OUD), inform public policy, and reduce harm in communities nationwide. It provides access to data at multiple spatial scales and time periods, already cleaned, merged, and documented. Read more about the project, our methodology, and insights.
OEPS is led by the Healthy Regions and Policies Lab, based at the Department of Geography & GIScience at the University of Illinois at Urbana-Champaign. It was developed for the Justice Community Overdose Innovation Network (JCOIN), a NIH HEAL Initiative, as part of the Methodology and Advanced Analytics Resource Center at the University of Chicago.
