We analyzed data from the Chicago Community Adult Health Study (CCAHS) (Morenoff et al., 2007), a household probability sample of 3,105 adults aged eighteen and over living in Chicago, Illinois, stratified into 343 neighborhood clusters previously defined by the Project on Human Development in Chicago Neighborhoods (PHDCN) (Sampson et al., 1997). The sample consists of 1240 non-Hispanic Blacks, 983 non-Hispanic Whites, 802 Hispanics, and eighty persons of other racial groups. Each neighborhood cluster typically included two Census tracts with meaningful physical and social identities and boundaries. Between May 2001 and March 2003, one individual from each of the selected households was interviewed, with a response rate of 71.8%. Data were weighted to match the 2000 Census population estimates for the city of Chicago in terms of age, race, and gender.
