A conceptual framework for studying emerging neighborhood effects on individual development is presented, identifying specific mechanisms and processes by which neighborhood disadvantage influences adolescent developmental outcomes. Using path analyses, the authors test the hypothesis that these organizational and cultural features of neighborhoods mediate the effects of ecological disadvantage on adolescent development and behavior; they then estimate the unique contribution of neighborhood effects on development using hierarchical linear modeling (HLM). The study involves samples of neighborhoods from two sites, Chicago and Denver. The analyses support the hypothesis that the effects of ecological disadvantage are mediated by specific organizational and cultural features of the neighborhood. The unique influence of neighborhood effects is relatively small, but in most cases these effects account for a substantial part of the variance explained by the HLM model.
