The growth of supportive housing over the last 30 years is grounded in research showing how in what ways it works best. As supportive housing evolves, communities need timely evidence to preserve, improve, and scale it for the future. This Research Agenda was initiated by CSH and is now a joint project of CSH and the National Center for Housing and Health. CSH and the Center are releasing the National Research Agenda for Supportive Housing to catalyze the next generation of research that centers people and communities and drives positive change. This research will be clearly communicated and tied to potential actions that communities, funders, and policymakers can take.
