Source: Authors' analysis of data from the Fragile Families and Child Wellbeing Study. Notes: Marginal effects for each sub-group are obtained by interacting sub-group variables with the neighborhood collective efficacy scale. Continuous variables are used for neighborhood disadvantage (national z-score) and family income (income-to-needs ratio); marginal effects are estimated at the values shown in parentheses. Models control for all socio-demographic and mental health history variables present in Exhibit 1, including sample city at birth.
