Welcome to the Evidence Library—a collection of research, resources, and supporting evidence that informs the work behind this site.

Here, you’ll find carefully selected studies, reports, data, and other credible sources that help explain what we know, how we know it, and why it matters. The library is designed to make the evidence easy to explore while providing transparency about the information and research behind our approach.
