Data Integration Across Jail & Homeless Services – Blueprint for Success

CSH selected the Center for Data Science and Public Policy (DSaPP) at the University of Chicago to develop a web-based data
integration tool, which was completed in The tool connects county jail administrative data from the justice system to homeless system data, through communities’ Homeless Management Information Systems (HMIS). The tool utilizes a matching algorithm developed using machine learning, which can match the integrated data by personal identifiers and report the overlap between systems to administrators. The data match can be done repeatedly over time, and can be used to understand the service profiles of persons who have long histories of engagement with these systems, advance policy, and programmatic solutions to address the needs of these persons and system service gaps.
