This report describes capacity and needs assessments of youth services in the District of Columbia. The assessments were conducted by the Urban Institute, Georgetown University, and the University of the District of Columbia in the summer of 1999. D.C. Mayor Anthony Williams requested these assessments to help guide the allocation of additional funds in the area of youth services. This report describes various indicators of needs across geographic regions of the city. Data come from existing District data sets, a survey of service providers; and interviews with service providers, parents, and youth related to early childhood development, K-12 academic achievement, post-school success, health and well-being, and crime. The indicators of need suggest that the need for additional youth services is high in most parts of the city. The areas east of the Anacostia River should receive about 40-50 percent of available resources, while the upper Northwest should receive a relatively small share of the new resources. Other areas should receive varying amounts. Most indicators show similar patterns of need. The findings also suggest that the hours of available capacity for youth services appear to be more than double the hours of actual use in all areas of the city. (SM)
