Development, demonstration, and research projects, supported by the Administration on Aging's Research and Development Grants Program, have two major objectives: to stimulate community efforts in behalf of the elderly, and to develop solutions to many social and economic problems of the elderly. As of September 1, 1969, 117 projects had been funded. These projects seek to: (1) coordinate the community's social, health, and welfare services for older people; (2) develop new services and new patterns of services to older people; (3) increase older people's opportunities for participation in community life and social productivity; (4) assist older people in maintaining human and community contacts; (5) define the effects, on the lives of older people, of changing social conditions; and (6) identify social and economic factors that are either beneficial or detrimental to the well-being of older people. The single general priority for Fiscal Year 1970 funding activities has been the development and demonstration of systems for coordinating comprehensive community services for older people. This priority is composed of two parts: the design and development of systems of service delivery; and the development, implementation, and testing of a range of specific services and service patterns. Current and completed projects are listed by purpose and state. (DB)
