This paper reports the findings of a study which examined the problems of homeless adults in New York City. The goals of the study were twofold: (1) to document and analyze the life circumstances of homeless adults in New York City who are dependent upon the public sector for their sustenance; and (2) to develop explicit standards for the provision of humane residences and services for the mentally disabled in the community. To collect data, informal interviews were conducted with willing homeless persons and with potential helping agents, and the homeless mentally disabled persons were observed. There are 36,000 homeless men and women in the city. The causes of homelessness include unemployment, insufficient decent low-cost housing, and the mass deinstitutionalization of mental patients. The immediate event which precipitates homelessness may include eviction, conditions in prior residences, failure of aftercare provisions for discharged mental patients, withdrawal of familial supports, and loss of income. The paper then examines patterns of survival among the homeless-- their needs, personal resources, and opportunities. Included among the recommendations made are the following. Shelter must be provided during the winter months. The conditions in the men's shelter, the Keener Building, and the Bowery hotels under contract with the city demand immediate attention. The admission regulations at the shelter care center for women are overly restrictive and should be revised. Long-term supportive housing is essential to complete the range of sheltering arrangements needed for homeless adults. Technical assistance and start up funding from both city and state sources should be targeted specifically for groups who wish to establish housing for the homeless. The Social Security Administration and the Department of Social Services should provide special assistance to homeless people. (Author/RM)
