It is the purpose of this study to present problems of unemployed youth in the context of changing manpower needs, labor force projections, and federally sponsored skill training programs. It is intended to be useful as a guide for administrators with job training responsibilities in the planning of vocational programs. Part I, dealing with National Trends, presents an analysis of unemployment and employment trends, and manpower requirements in the 1970's. Data on federally sponsored vocational training programs, and tables describing projected manpower needs are included. Part II, Profiles of The States, explores the relationship between net migration, labor force projections, unemployment, and federally sponsored training programs. Maps and tables of states are used to present extensive data. A future volume in the study will present a profile of nine American cities. (CH)
