Understanding the relationship between ethnicity and youth violence requires an analysis of specific developmental contexts that can vary by ethnicity. One of the most important developmental contexts for children is the community where they grow up. In the United States and elsewhere, children from certain ethnic groups have disproportionately grown up in neighborhoods characterized by high levels of segregation and disadvantage, as indicated by poverty and inequality (Evans, 2004;Hernandez, 2004;Massey & Denton, 1996;Wilson, 1996). Several aspects of these disadvantaged contexts can interfere with successful adaptations to prosocial behavioral expectations and facilitate the learning, use, and escalation of aggressive, violent, and delinquent behavior during childhood and into adulthood (Sampson & Laub, 2004).Ethnic minority youth often grow up in ecological contexts that have fewer resources to foster the development of protective factors that reduce risk for violence compared with their nonminority peers. Otherwise stated, a child's ethnicity can increase the likelihood that he or she will be raised 17
