This report examines the unique aspects of homelessness among youth ages 16 to 21. Section I reviews existing literature and data on the size, characteristics, and needs of homeless youth. Section II summarizes New York State's current efforts on their behalf. Section III analyzes obstacles to serving this population. Section IV outlines an action plan for New York State to improve its services. Although New York State has been a leader in recognizing the needs of runaway and homeless youth, the scope and methods of the present service delivery system fail to meet the magnitude and nature of the crisis. Probably the greatest deficiency is the lack of services available to older homeless youth as compared to those for youth and children under 16. Other gaps and barriers include the unavailability of transitional services which address long-term rather than emergency needs; inadequate coordination of services such as education, health care, and housing; and limitations of current funding sources. The recommendations address five areas: (1) coordination between state agencies; (2) implementation of a formal mechanism to ensure coordinated planning and service delivery at the local level; (3) development of transitional services; (4) improved preparation for independent living of youth in residential child care; and (5) evaluation and research in developing and improving the service delivery systems.
