This case study examines the development and problems of the Mon-Yough Community Action Committee, Inc. (MYCAC), one of the local anti-poverty agencies in Allegheny County, Pennsylvania. The agency's major effort is to overcome problems created by the decline of the local steel industry by supporting existing welfare agencies, and through such innovative institutions as community centers. The target groups include older retired persons, youth (especially late adolescents), high school dropouts, workers facing displacement because of technological change, socially disadvantaged groups (Negroes), and the physically handicapped. MYCAC jurisdiction does not overlap with that of the county; this fact has made program coordination difficult because of a relative lack of appropriate organizations which might naturally join community action in the area, and by the double requirement that it relate its activities downward to 31 local community action committees, and upwards to the Allegheny County community action agency. (Seventeen tables of demographic and economic data are included and discussed.) (dm)
