The study . . . examines the experience of 943 residents of permanent supportive housing in Philadelphia during the years 2001 to 2005. The characteristics of their permanent housing, circumstances of leaving, and the post-permanent housing careers of leavers were identified. The study also focused on the impact of factors associated with leaving permanent housing and post-permanent housing careers, such as the length of the period of homelessness and the degree and nature of disability. The results will be of interest to policymakers and service providers who design, administer, and/or operate permanent housing programs that promote residential stability and self- sufficiency.
