AbstractThe impact of neighborhood cultural and institutional lye upon rates of delinquency among black male adolescents is examined. Focusing on three adjacent black neighborhoods at varying levels of black population change, this paper presents direct tests of three corollaries derived from a causal model adapted from Shaw and McKays cultural transmission theory of delinquency. The preliminary results are compatible with the model: the level of delinquency is higher in a racially changing than in two more racially stable neighborhoods. Other findings. however, fail to support the cultural transmission interpretation of these results. Contrary to Shaw and McKay, delinquency is lowest in the area where criminal influences are the most pronounced. This anomaly is discussed and interpreted in a manner consistent with De FIeur and Quinney's (1966) reformulation of differential association theory.
