Punishing and toxic neighborhood environments independently predict the intergenerational social mobility of black and white children.

Abstract

We use data on intergenerational social mobility by neighborhood to examine how social and physical environments beyond concentrated poverty predict children's long-term well-being. First, we examine neighborhoods that are harsh on children's development: those characterized by high levels of violence, incarceration, and lead exposure. Second, we examine potential supportive or offsetting mechanisms that promote children's development, such as informal social control, cohesion among neighbors, and organizational participation. Census tract mobility estimates from linked income tax and Census records are merged with surveys and administrative records in Chicago. We find that exposure to neighborhood violence, incarceration, and lead combine to independently predict poor black boys' later incarceration as adults and lower income rank relative to their parents, and poor black girls' teenage motherhood. Features of neighborhood social organization matter less, but are selectively important. Results for poor whites also show that toxic environments independently predict lower social mobility, as do features of social organization, to a lesser extent. Overall, our measures contribute a 76% relative increase in explained variance for black male incarceration beyond that of concentrated poverty and other standard characteristics, an 18% increase for black male income rank (70% for whites), and a 17% increase for teenage motherhood of black girls (40% for whites).
