This paper discusses the effects of President Reagan's budget cuts on federally supported human service programs in New York. Various programs are analyzed to determine their vulnerability to budget reductions. It is suggested that employment, nutrition and health programs are most likely to be cut while education, adoption assistance, senior citizen, and community development programs are not in immediate danger. A review of the federal block grant approach reveals the possibility of an unequal regional distribution of funds that will hurt the Northeastern United States, especially New York City. The need for state and local governments to offset this reduction in funds is discussed. Appendices to the report contain a collection of fact sheets on human service programs, and a general analysis of types of programs, their constituencies, their vulnerability, and their potential organizational allies.
