Comment on Dennis P. Culhane et al.’s “Testing a typology of family homelessness based on patterns of public shelter utilization in four U.S. jurisdictions: Implications for policy and program planning”

A comprehensive typology of homeless families would help us understand how to provide services and supports appropriate to particular subgroups. In their attempt to establish such a typology, Culhane and his colleagues employ administrative data sets to correlate shelter use with behavioral indicators. These data sets are limited in that they fail to incorporate the complex, intense, and sometimes traumatic experiences that characterize the lives of homeless families, causing this study to fall short of what is required to create an accurate typology. Among the areas overlooked by this approach are the high levels of traumatic stress and violence in the lives of homeless families, children's needs, and the interactions between parents and children. When only limited research is available, there is a danger that even modest findings will be used to support broad policy directions. Further research is needed to arrive at a defensible typology.
