Is Homelessness Itself Trauma?

I feel like I've hit gold with my recent discovery of the Homeless Resource Center, a project of the US Department of Health and Human Services (Substance Abuse and Mental Health Services Administration). The project looks for solutions to homelessness and focuses on the history that homeless people have with mental illness, substance abuse, and trauma. Furthermore, they categorize homelessness as a trauma in and of itself, and look for public health solutions to treating trauma and homelessness. The Web site is chock full of data, including the recently published and publicly available Journal of Primary Prevention. The Web site seeks to bring together up to date research on this issue.We have been struggling with how to frame the issue of homelessness and violence directly, since homeless people have many different experiences with violence and often how they became homeless seems as important as what they have experienced since. It occurs to me that looking at the problem through the lens of trauma might be a useful way to deal with the problem.
