As this special issue of the journal well reflects, much progress has been made in homelessness research. That progress has been matched with advances in homelessness policy and programming, nearly all of it informed by the contributions of the research community. While the imperatives of policy-making have required decisions to be made with imperfect knowledge, a substantial enough convergence of theory and evidence has enabled policymakers to shift homelessness policy and practice in important ways. Those shifts have also prefigured some of policymakers’ needs from the research community in the future.
