The three boys in the Manhattan neighborhood were of Hispanic/Latino origin and the two girls were African American. Conversely, the four boys in the Bronx neighborhood were African American, and the girl was a recent immigrant from South America. Four adolescents in Manhattan had lived in their neighborhoods since birth and one boy moved to the neighborhood 6 years prior to the interview. In the Bronx, two boys had lived in their neighborhoods since birth whereas two boys had lived there for 8 years. The girl moved to the Bronx a year before the interview.
