The consequences of lead exposure for later crime are theoretically compelling, but direct evidence from representative, longitudinal samples is sparse. By capitalizing on an original follow‐up of more than 200 infants from the birth cohort of the Project on Human Development in Chicago Neighborhoods matched to their blood lead levels from around age 3 years, we provide several tests. Through the use of four waves of longitudinal data that include measures of individual development, family background, and structural inequalities in how lead becomes embodied, we assess the hypothesized link between early childhood lead poisoning and both parent‐reported delinquent behavior and official arrest in late adolescence. We also test for mediating developmental processes of impulsivity and anxiety or depression. The results from multiple analytic strategies that make different assumptions reveal a plausibly causal effect of childhood lead exposure on adolescent delinquent behavior but no direct link to arrests. The results underscore lead exposure as a trigger for poisoned development in the early life course and call for greater integration of the environment into theories of individual differences in criminal behavior.

Mare. 2017. “Urban Income Inequality and the Great Recession in Sunbelt Form: Disentangling Individual and Neighborhood-Level Change in Los Angeles.” RSF: The Russell Sage Foundation Journal of the Social Sciences 3: 102-128. Publisher's Version Abstract
New social transformations within and beyond the cities of classic urban studies challenge prevailing accounts of spatial inequality. This paper pivots from the Rust Belt to the Sunbelt accordingly, disentangling persistence and change in neighborhood median income and concentrated income extremes in Los Angeles County. We first examine patterns of change over two decades starting in 1990 for all Los Angeles neighborhoods. We then analyze an original longitudinal study of approximately six hundred Angelenos from 2000 to 2013, assessing the degree to which contextual changes in neighborhood income arise from neighborhood-level mobility or individual residential mobility. Overall we find deep and persistent inequality among both neighborhoods and individuals. Contrary to prior research, we also find that residential mobility does not materially alter neighborhood economic conditions for most race, ethnic, and income groups. Our analyses lay the groundwork for a multilevel theoretical framework capable of explaining spatial inequality across cities and historical eras.

Objectives. To assess the relationships between childhood lead exposure and 3 domains of later adolescent health: mental, physical, and behavioral.

Methods. We followed a random sample of birth cohort members from the Project on Human Development in Chicago Neighborhoods, recruited in 1995 to 1997, to age 17 years and matched to childhood blood test results from the Department of Public Health. We used ordinary least squares regression, coarsened exact matching, and instrumental variables to assess the relationship between average blood lead levels in childhood and impulsivity, anxiety or depression, and body mass index in adolescence. All models adjusted for relevant individual, household, and neighborhood characteristics.

Results. After adjustment, a 1 microgram per deciliter increase in average childhood blood lead level significantly predicts 0.06 (95% confidence interval [CI] = 0.01, 0.12) and 0.09 (95% CI = 0.03, 0.16) SD increases and a 0.37 (95% CI = 0.11, 0.64) point increase in adolescent impulsivity, anxiety or depression, and body mass index, respectively, following ordinary least squares regression. Results following matching and instrumental variable strategies are very similar.

Conclusions. Childhood lead exposure undermines adolescent well-being, with implications for the persistence of racial and class inequalities, considering structural patterns of initial exposure. 

The environmental fragility of cities under advanced urbanization has motivated extensive efforts to promote the sustainability of urban ecosystems and physical infrastructures. Less attention has been devoted to neighborhood inequalities and fissures in the civic infrastructure that potentially challenge social sustainability and the capacity of cities to collectively address environmental challenges. This article draws on a program of research in three American cities—Boston, Chicago, and Los Angeles—to develop hypotheses and methodological strategies for assessing how the multidimensional and multilevel inequalities that characterize contemporary cities bear on sustainability. In addition to standard concerns with relative inequality in income, the article reviews evidence on compounded deprivation, racial cleavages, civic engagement, institutional cynicism, and segregated patterns of urban mobility and organizational ties that differentially connect neighborhood resources. Harnessing “ecometric” measurement tools and emerging sources of urban data with a theoretically guided framework on neighborhood inequality can enhance the pursuit of sustainable cities, both in the United States and globally.

In 1986, the National Research Council published a two-volume report, Criminal Careers andCareer Criminals.” This work generated fierce debates central to the field of criminology and pitted some of the biggest names in the business against one another. In this paper, we consider the last 30 years and ask whether the report was an intellectual turning point. Our answer is that while the report did change the methodological direction of criminology, it lacked a theoretical explanation of the dynamics of crime. After the report was published, several efforts attempted to fill this breach. We reflect on the role that the Criminal Careers report played in our own work, from the time of the report’s release to the development and assessment of what is now known as the age-graded theory of informal social control and the broader field of “life-course criminology.”
