The elderly population is rapidly expanding while the core tax-paying populaiton is shrinking. The ratio of working Americans to retired Americans will drop from 5 to 1, to 2 to 1 over the next 50 years. As the elderly population grows, and subsequently the need for adequate elderly health and housing services grows, the resources to provide services will decrease. Finding a more efficient means of service delivery is of paramount importance. This document provides an overview of aging demographics and barriers to the coordination of health and housing services, and examines the costs of aging services and methods of service delivery. Three approaches to the coordination of health and housing services are provided along with lessons from providers and federal, state, and local opportunities for the coordination of health and housing services.
