Across sites, primary caregivers self-identified as belonging to the following ethnic groups: 50% European American, 28% African American, 13% biracial, and 9% other groups (e.g., American Indian, Native Hawaiian). Thirteen percent of the sample reported being Hispanic American. During the 2002 to 2003 screening period, more than two thirds of those families enrolled in the project had an annual income of less than $20,000, and the average number of family members per household was 4.5 (SD = 1.63). Forty-one percent of the adult population had a high school diploma or GED equivalency, and an additional 32% had 1 to 2 years of post–high school training.
