An innovative new study has included longitudinal community-level data to evaluate the impact of community investment on the relationship between permanent supportive housing (PSH) and chronic homelessness. The study, The Relationship between Community Investment in Permanent Supportive Housing and Chronic Homelessness, is the first published study to look beyond the effectiveness of PSH at the individual level.
The study used data from 372 Continua of Care (CoC) between 2007 and 2012 collected during point-in-time (PIT) homelessness counts for the U.S Department of Housing and Urban Development. An analysis of the data revealed a correlation between increased investment in PSH units and a decrease in chronic homelessness over time. The study indicates that the inverse relationship grows over time. The study estimates that an increase of one PSH unit per 10,000 adults is correlated with a 2% decrease in chronically homeless people in the first year. Over the course of the study between 2007 and 2012, the average number of PSH beds increased by 57% while the average rates of chronic homelessness decreased by 35%, leading researchers to believe that PSH units will have a stronger effect on decreasing homelessness over time.
