The Runaway and Homeless Youth Act (RHYA) provides foundational support to address youth and young adult homelessness across the country. These grants, administered by the U.S. Department of Health and Human Services (HHS), began providing resources in 1974 and allowed local systems of care to be developed and shaped by the unique needs of each region, their available resources, and their local policy priorities. Remarkably similar systems of care emerged in local communities all over the U.S., including: street outreach, emergency shelter, aftercare, education and employment, health care, behavioral health, transitional housing, family intervention, and independent housing options. This continuum of care helps fully prepare youth to achieve successful outcomes: safe exit from homelessness, family reunification, establishment of permanent connection(s), employment, and sustainable independent living.
