Homelessness has been, and continues to be, a complex issue around the world. Urban planners, policy makers, and non-profit organizations have a strong interest in improving the ways in which they help the homeless. The impacts of politics, religious beliefs, budget constraints, and the status quo on their efforts to develop and implement sustainable solutions to homelessness have already been extensively studied. To the extent that research guides their actions, this paper makes the case for incorporating the place dimension of sustainability, Geographic Information Systems (GIS), and spatial analysis into solutions to homelessness for long-lasting results. An analysis of 30 relevant peer reviewed papers reveals the staggering absence of the place dimension of sustainability, GIS, and spatial analysis from solutions to homelessness that are being considered sustainable. These findings have implications for future research and the development of truly sustainable solutions to homelessness.
