Winter, Alix S., and Robert J. Sampson. 2017. “From Lead Exposure in Early Childhood to Adolescent Health: A Chicago Birth Cohort.” American Journal of Public Health 107 (9): 1496-1501. Publisher's Version Abstract

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.

Sampson, Robert J., and John H. Laub. 2016. “Turning Points and the Future of Life-Course Criminology: Reflections on the 1986 Criminal Careers Report.” Journal of Research in Crime and Delinquency 53: 321-335. Publisher's Version Abstract
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.”
James J. Heckman, John Eric Humphries, and Tim Kautz make a powerful case for noncognitive skills--or what they conceptualize as character--as an explanation of educational achievement and other important outcomes in life. They do so while exposing the myth of the GED, arguing that the GED harms its intended beneficiaries by failing to instill the character skills that predict adult success. Childhood interventions to build personal character, especially self-control, are emphasized. The Myth of Achievement Tests is a major contribution, but I integrate relevant research on crime and social control across the life course that motivates a more dynamic conceptualization of character. I also review evidence on the environment as a source of both cognitive and noncognitive skills, including exposure to concentrated deprivation, violence, and lead toxicity. Moreover, I review evidence suggesting that social reactions to character shape life chances in ways not reducible to individual propensities, such as changes in criminal-justice policy that created large cohort differentials in incarceration for the same underlying behaviors. Social context and the character of American society itself are thus central to fostering individual character--not just skills but the desire to conform. It follows that self-control and social control need to be better unified theoretically and in designing interventions.

Sampson, Robert J., and Alix Winter. 2016. “The Racial Ecology of Lead Poisoning: Toxic Inequality in Chicago Neighborhoods, 1995-2013.” DuBois Review: Social Science Research on Race 13 (2). Publisher's Version Abstract
This paper examines the racial ecology of lead exposure as a form of environmental inequity, one with both historical and contemporary significance. Drawing on comprehensive data from over one million blood tests administered to Chicago children from 1995-2013 and matched to over 2300 geographic block groups, we address two major questions: (1) What is the nature of the relationship between neighborhood-level racial composition and variability in children’s elevated lead prevalence levels? And (2) what is the nature of the relationship between neighborhood-level racial composition and rates of change in children’s prevalence levels over time within neighborhoods? We further assess an array of structural explanations for observed racial disparities, including socioeconomic status, type and age of housing, proximity to freeways and smelting plants, and systematic observations of housing decay and neighborhood disorder. Overall, our theoretical framework posits lead toxicity as a major environmental pathway through which racial segregation has contributed to the legacy of Black disadvantage in the United States. Our findings support this hypothesis and show alarming racial disparities in toxic exposure, even after accounting for possible structural explanations. At the same time, however, our longitudinal results show the power of public health policies to reduce racial inequities.

This paper assesses the state of life-course criminology and argues that its major limitation to date is the general failure to incorporate social change. Invoking the concept of cohort differences in aging because of macro-level change, I discuss some of the watershed changes of recent times, including the historic crime decline, the technological revolution, massive immigration and urbanization, rises in inequality, and the Great Recession. I then introduce a new study from Chicago that attempts to link individual development and pathways of crime to some of these large-scale social changes, capitalizing on a cohort sequential design from the Project on Human Development in Chicago Neighborhoods. I conclude with implications for global criminology, especially the role of urbanization, ethnic diversity, and inequality in Asia.

This paper investigates acute, compounded, and persistent deprivation in a representative sample of Chicago adolescents transitioning to young adulthood. Our investigation, based on four waves of longitudinal data from 1995 to 2013, is motivated by three goals. First, we document the prevalence of individual and neighborhood poverty over time, especially among whites, blacks, and Latinos. Second, we explore compounded deprivation, describing the extent to which study participants are simultaneously exposed to individual and contextual forms of deprivation—including material deprivation (such as poverty) and social-organizational deprivation (for example, low collective efficacy)—for multiple phases of the life course from adolescence up to age thirty-two. Third, we isolate the characteristics that predict transitions out of compounded and persistent poverty. The results provide new evidence on the crosscutting adversities that were exacerbated by the Great Recession and on the deep connection of race to persistent and compounded deprivation in the transition to adulthood.

This article focuses on stability and change in “mixed middle-income” neighborhoods. We first analyze variation across nearly two decades for all neighborhoods in the United States and in the Chicago area, particularly. We then analyze a new longitudinal study of almost 700 Chicago adolescents over an 18-year span, including the extent to which they are exposed to different neighborhood income dynamics during the transition to young adulthood. The concentration of income extremes is persistent among neighborhoods, generally, but mixed middle-income neighborhoods are more fluid. Persistence also dominates among individuals, though Latino-Americans are much more likely than African Americans or whites to be exposed to mixed middle-income neighborhoods in the first place and to transition into them over time, even when adjusting for immigrant status, education, income, and residential mobility. The results here enhance our knowledge of the dynamics of income inequality at the neighborhood level, and the endurance of concentrated extremes suggests that policies seeking to promote mixed-income neighborhoods face greater odds than commonly thought.
O’Brien, Daniel, Robert J. Sampson, and Christopher Winship. 2015. “Ecometrics in the Age of Big Data: Measuring and Assessing ‘Broken Windows’ Using Large-scale Administrative Records.” Sociological Methodology 45: 101-147. Website Abstract
The collection of large-scale administrative records in electronic form by many cities provides a new opportunity for the measurement and longitudinal tracking of neighborhood characteristics, but one that will require novel methodologies that convert such data into research-relevant measures. The authors illustrate these challenges by developing measures of “broken windows” from Boston’s constituent relationship management (CRM) system (aka 311 hotline). A 16-month archive of the CRM database contains more than 300,000 address-based requests for city services, many of which reference physical incivilities (e.g., graffiti removal). The authors carry out three ecometric analyses, each building on the previous one. Analysis 1 examines the content of the measure, identifying 28 items that constitute two independent constructs, private neglect and public denigration. Analysis 2 assesses the validity of the measure by using investigator-initiated neighborhood audits to examine the “civic response rate” across neighborhoods. Indicators of civic response were then extracted from the CRM database so that measurement adjustments could be automated. These adjustments were calibrated against measures of litter from the objective audits. Analysis 3 examines the reliability of the composite measure of physical disorder at different spatiotemporal windows, finding that census tracts can be measured at two-month intervals and census block groups at six-month intervals. The final measures are highly detailed, can be tracked longitudinally, and are virtually costless. This framework thus provides an example of how new forms of large-scale administrative data can yield ecometric measurement for urban science while illustrating the methodological challenges that must be addressed.

J., Ursano Robert, Jodi B. A. McKibben, Dori B. Reissman, Xian Liu, Leming Wang, Robert J. Sampson, and Carol S. Fullerton. 2014. “Posttraumatic Stress Disorder and Community Collective Efficacy following the 2004 Florida Hurricanes.” PLoS ONE 9 (2): e88467. Publisher's Version Abstract
There is a paucity of research investigating the relationship of community-level characteristics such as collective efficacy and posttraumatic stress following disasters. We examine the association of collective efficacy with probable posttraumatic stress disorder and posttraumatic stress disorder symptom severity in Florida public health workers (n = 2249) exposed to the 2004 hurricane season using a multilevel approach. Anonymous questionnaires were distributed electronically to all Florida Department of Health personnel nine months after the 2004 hurricane season. The collected data were used to assess posttraumatic stress disorder and collective efficacy measured at both the individual and zip code levels. The majority of participants were female (80.42%), and ages ranged from 20 to 78 years (median = 49 years); 73.91% were European American, 13.25% were African American, and 8.65% were Hispanic. Using multi-level analysis, our data indicate that higher community-level and individual-level collective efficacy were associated with a lower likelihood of having posttraumatic stress disorder (OR = 0.93, CI = 0.88–0.98; and OR = 0.94, CI = 0.92–0.97, respectively), even after adjusting for individual sociodemographic variables, community socioeconomic characteristic variables, individual injury/damage, and community storm damage. Higher levels of community-level collective efficacy and individual-level collective efficacy were also associated with significantly lower posttraumatic stress disorder symptom severity (b = −0.22, p<0.01; and b = −0.17, p<0.01, respectively), after adjusting for the same covariates. Lower rates of posttraumatic stress disorder are associated with communities with higher collective efficacy. Programs enhancing community collective efficacy may be an important part of prevention practices and possibly lead to a reduction in the rate of posttraumatic stress disorder post-disaster.
Sampson, Robert J. 2014. “Inequality from the Top Down and Bottom Up: Toward a Revised Wacquant.” Ethnic and Racial Studies Review 37: 1732-1738. Publisher's Version Abstract
In this response I focus on two major themes in Wacquant's trilogy: (1) punishment and the state; and (2) territorial stigmatization. I discuss evidence that supports elements of Wacquant's argument, while at the same time demonstrating the need for an account that brings mediating institutional processes of the state, violence, the civil sphere and neighbourhood mechanisms more fully into the larger theoretical picture. I conclude that ‘bottom-up’ processes of inequality must be integrated with ‘top-down’ forces of the state to advance our theoretical understanding of penality and spatial marginality in federated and unitary governments alike.
Hwang, Jackelyn, and Robert J. Sampson. 2014. “Divergent Pathways of Gentrification: Racial Inequality and the Social Order of Renewal in Chicago Neighborhoods.” American Sociological Review 79 (4). Website Abstract
Gentrification has inspired considerable debate, but direct examination of its uneven evolution across time and space is rare. We address this gap by developing a conceptual framework on the social pathways of gentrification and introducing a method of systematic social observation using Google Street View to detect visible cues of neighborhood change. We argue that a durable racial hierarchy governs residential selection and, in turn, gentrifying neighborhoods. Integrating census data, police records, prior street-level observations, community surveys, proximity to amenities, and city budget data on capital investments, we find that the pace of gentrification in Chicago from 2007 to 2009 was negatively associated with the concentration of blacks and Latinos in neighborhoods that either showed signs of gentrification or were adjacent and still disinvested in 1995. Racial composition has a threshold effect, however, attenuating gentrification when the share of blacks in a neighborhood is greater than 40 percent. Consistent with theories of neighborhood stigma, we also find that collective perceptions of disorder, which are higher in poor minority neighborhoods, deter gentrification, while observed disorder does not. These results help explain the reproduction of neighborhood racial inequality amid urban transformation.
