The New York/New York Agreement Cost Study: The Impact of Supportive Housing on Services Use for Homeless Mentally Ill Individuals

A research team from the Center for Mental Health Policy and Services Research, University of
Pennsylvania, has published the most comprehensive study to date on the effects of homelessness
and service-enriched housing on mentally ill individuals’ use of publicly funded services.
Five years in the making, the study measures for the first time the full extent of homeless
mentally ill individuals’ dependence on an array of publicly funded emergency service systems.
The study also ascertains the degree to which this dependence is reduced by placement into
service-enriched housing. And by comparing precise measurements of the cost of the service
use to that of the housing, the study has determined exactly how much the public saves by
placing homeless mentally ill people into service-enriched housing, and how little this housing
ultimately costs.
