Neighborhood Characteristics, Peer Networks, and Adolescent Violence

Although ecological researchers consistently find high rates of crime and violence within socioeconomically disadvantaged neighborhoods, there is little consensus as to why this pattern exists. To address this question, we use data from the National Longitudinal Study of Adolescent Health (n=12,747) to examine three related research questions. Are neighborhood characteristics associated with adolescent violence net of compositional and selection effects? Are neighborhood characteristics associated with adolescents’ exposure to violent and prosocial peers? Does peer exposure mediate the neighborhood characteristics–violence association? Results indicate that across a wide range of neighborhoods, socioeconomic disadvantage is positively related to adolescent violence net of compositional and selection effects. Additionally, neighborhood disadvantage is associated with exposure to violent peers, and peer exposure mediates part of the neighborhood disadvantage–violence association. Joining structural and cultural explanations for violence, our findings suggest that neighborhood disadvantage influences adolescent violence indirectly by increasing opportunities for youth to become involved in violent peer networks.     

DECOMPOSING THE PEER EFFECT ON ADOLESCENT SUBSTANCE USE: MEDIATION,NONLINEARITY, AND DIFFERENTIAL NONLINEARITY*

Although the correlation between peer delinquency and delinquency is one of the most consistently demonstrated findings in delinquency research, researchers have focused primarily on the direct, linear, and additive effects of peers in statistical models, rather than on empirically modeling mediating, nonlinear, and moderating processes that are specified by theory. To address these issues, we measure respondent delinquency and peer delinquency with illegal substance use and then decompose the effect of peer substance use on self‐reported substance use. Logistic hierarchical models on a sample of adolescents from the Project on Human Development in Chicago Neighborhoods (PHDCN) indicate that the effect of peer substance use on self‐reported substance use is partially mediated by perceptions of the health risks of substance use. In addition, the direct statistical effect of peers is nonlinear: On average, the peer effect decreases at higher values of peer substance use, which is consistent with a “saturation” effect. We also find that the functional form of the peer substance use/substance use relationship is dependent on the neighborhood context. In neighborhoods with more opportunities for crime, the peer effect is initially strong but decreases as peer substance use increases, which is consistent with a saturation effect. Conversely, in neighborhoods with fewer opportunities for crime, the effect of peers is initially small, but as delinquent peer associations increase, the peer effect increases multiplicatively.     

ASSESSING NEIGHBORHOOD AND SOCIAL PSYCHOLOGICAL INFLUENCES ON CHILDHOOD VIOLENCE IN AN AFRICAN‐AMERICAN SAMPLE*

The present study examines the extent to which neighborhood and social psychological influences predict childhood violence among 867 African‐American youth. The results showed that neighborhood affluence was the only neighborhood‐level variable to exert a significant influence on childhood violence. Furthermore, childhood violence was significantly related to social psychological influences, such as adopting a street code, associating with violent peers, parental use of violence, and quality parenting. Overall, the findings suggested that simply living in a violent neighborhood does not produce violent children, but that family, peer, and individual characteristics play a large role in predicting violence in childhood.     

LEARNING TO BE BAD: ADVERSE SOCIAL CONDITIONS,SOCIAL SCHEMAS,AND CRIME*

In this article, we develop and test a new approach to explain the link between social factors and individual offending. We argue that seemingly disparate family, peer, and community conditions lead to crime because the lessons communicated by these events are similar and promote social schemas involving a hostile view of people and relationships, a preference for immediate rewards, and a cynical view of conventional norms. Furthermore, we posit that these three schemas are interconnected and combine to form a criminogenic knowledge structure that results in situational interpretations legitimating criminal behavior. Structural equation modeling with a sample of roughly 700 African American teens provided strong support for the model. The findings indicated that persistent exposure to adverse conditions such as community crime, discrimination, harsh parenting, deviant peers, and low neighborhood collective efficacy increased commitment to the three social schemas. The three schemas were highly intercorrelated and combined to form a latent construct that strongly predicted increases in crime. Furthermore, in large measure, the effect of the various adverse conditions on increases in crime was indirect through their impact on this latent construct. We discuss the extent to which the social‐schematic model presented in this article might be used to integrate concepts and findings from several major theories of criminal behavior.     

Violence in Urban Neighborhoods: A Longitudinal Study of Collective Efficacy and Violent Crime

Objectives

Cross-sectional studies consistently find that neighborhoods with higher levels of collective efficacy experience fewer social problems. Particularly robust is the relationship between collective efficacy and violent crime, which holds regardless of the socio-structural conditions of neighborhoods. Yet due to the limited availability of neighborhood panel data, the temporal relationship between neighborhood structure, collective efficacy and crime is less well understood.

Methods

In this paper, we provide an empirical test of the collective efficacy-crime association over time by bringing together multiple waves of survey and census data and counts of violent crime incident data collected across 148 neighborhoods in Brisbane, Australia. Utilizing three different longitudinal models that make different assumptions about the temporal nature of these relationships, we examine the reciprocal relationships between neighborhood features and collective efficacy with violent crime. We also consider the spatial embeddedness of these neighborhood characteristics and their association with collective efficacy and the concentration of violence longitudinally.

Results

Notably, our findings reveal no direct relationship between collective efficacy and violent crime over time. However, we find a strong reciprocal relationship between collective efficacy and disadvantage and between disadvantage and violence, indicating an indirect relationship between collective efficacy and violence.

Conclusions

The null direct effects for collective efficacy on crime in a longitudinal design suggest that this relationship may not be as straightforward as presumed in the literature. More longitudinal research is needed to understand the dynamics of disadvantage, collective efficacy, and violence in neighborhoods.

     

Violent Crime,Residential Instability and Mobility: Does the Relationship Differ in Minority Neighborhoods?

This study examines the reciprocal relationship between violent crime and residential stability in neighborhoods. We test whether the form of stability matters by comparing two different measures of stability: a traditional index of residential stability and a novel approach focusing specifically on the stability of homeowners. We also examine whether the racial/ethnic composition of the neighborhood in which this stability occurs affects the instability—violent crime relationship. To test the simultaneous relationship between residential mobility and crime we estimate a dual multivariate latent curve model of the change in the violent crime rate and the change in the rate of home sales while controlling for neighborhood socioeconomic and demographic characteristics using data from Los Angeles between 1992 and 1997. Results indicate that the initial level of violent crime increases the trajectory of residential instability in subsequent years, whether the instability is measured as homeowner turnover specifically, or based on an index of all residents. However, the effect of instability on violent crime is only apparent when measuring instability based on an index of general residential turnover and not when including the presence of owners in this measure, or when measuring it based on homeowner turnover. We consistently find that stable highly Latino communities exhibit a protective effect against violence.     

DIFFERENTIAL SUSCEPTIBILITY? IMMIGRANT YOUTH AND PEER INFLUENCE*

There is reason to suspect that lower levels of exposure to criminogenic peer‐based risks help explain why immigrant youth are less involved in crime and violence. However, it also is possible that if and when they do encounter these risks, immigrant youth are more vulnerable to them than are native‐born youth. Drawing from literature on the adaptation experiences of immigrant adolescents, we hypothesize that immigrant youth will be relatively more susceptible to the effects of both 1) exposure to deviant peers and 2) unstructured and unsupervised socializing with peers when compared with their nonimmigrant counterparts. Using a sample of approximately 1,800 adolescents from the Project on Human Development in Chicago Neighborhoods (PHDCN) study, we find support for our first hypothesis but not the second. Specifically, in both cross‐sectional and longitudinal models, we find that exposure to deviant peers has a greater impact on violence among immigrant youth than it does for native‐born youth. Furthermore, this pattern of results is supported with supplemental, sensitivity analysis using the AddHealth data. In contrast, there are no statistically significant differences across immigrant generation status with regard to the effect of informal socializing with peers on violence.     

NEIGHBORHOOD HOUSING INVESTMENTS AND VIOLENT CRIME IN SEATTLE, 1981–2007*

Despite significant advances in the study of neighborhoods and crime, criminologists have paid surprisingly less attention to the extralocal forces that shape violence. To address this issue, we draw on an emerging body of work that stresses the role of home mortgage lending—a resource secured via interaction with external actors—in reducing neighborhood violence and extend it by addressing concerns that the lending–violence relationship is spurious and confounded by simultaneity. We explore the longitudinal relationship between residential mortgage lending and violence in Seattle with a pooled time series of 118 census tracts over 27 years, and we instrument our endogenous predictors (home mortgage lending and violent crime) with changes in their levels from prior periods. Employing Arellano–Bond difference models, we assess both the effect of mortgage lending on violent crime as well as the effect of violent crime levels on mortgage activity. We find that infusions of home mortgage lending yield reductions in subsequent violent crime; yet the impact of violent crime on subsequent lending is not significant. Results underscore the importance of incorporating external forces such as home mortgage lending into explanations of neighborhood violence.     

THE SOCIAL ECOLOGY OF PUBLIC SPACE: ACTIVE STREETS AND VIOLENT CRIME IN URBAN NEIGHBORHOODS

Drawing on one element of the discussion by Jacobs ( 1961 ) of the social control benefits of “eyes on the street,” this article explores the link between the prevalence of active streets and violence in urban neighborhoods. Three distinct data sources from the Project on Human Development in Chicago Neighborhoods are merged to explore the functional form and potential contingency of the active streets–violence relationship: 1) video data capturing the presence of people on neighborhood streets; 2) longitudinal data on adolescents (11 to 16 years of age) and their self‐reports of witnessing severe violence; and (3) community survey data on neighborhood social organizational characteristics. The results from multilevel models indicate that the proportion of neighborhood streets with adults present exhibits a nonlinear association with exposure to severe violence. At low prevalence, the increasing prevalence of active streets is positively associated with violence exposure. Beyond a threshold, however, increases in the prevalence of active streets serve to reduce the likelihood of violence exposure. The analyses offer no evidence that the curvilinear association between active streets and violence varies by levels of collective efficacy, and only limited evidence that it varies by anonymity. Analyses of data on homicide and violent victimization corroborate these findings.     

THE ELUSIVE RELATIONSHIP BETWEEN COMMUNITY ORGANIZATIONS AND CRIME: AN ASSESSMENT ACROSS DISADVANTAGED AREAS OF THE SOUTH BRONX

Several theoretical perspectives posit a negative association between the extent of a neighborhood's organizational infrastructure and crime; yet, empirical support for this proposition has been limited in that researchers generally examine only a few types of organizations or combine them into one aggregate measure. Studies with few measures may omit organizations that are effective at reducing crime, whereas those using aggregate measures obscure differences across organizations in their ability to control crime. Using data from 74 block groups in the South Bronx, NY, this research seeks to specify more clearly the relationship between organizations and crime in a disadvantaged urban environment. We examine the relationship among nine different types of organizations and violent and property crime controlling for prior crime, land use, and area sociodemographic characteristics. Consistent with theories that highlight the importance of organizations for establishing ties outside the neighborhood, we find that block groups with more organizations that bridge to the larger community experience a decrease in crime. Property crime also is reduced in block groups with more organizations that promote the well‐being of families and children. We find that schools are associated with an increase in property crime, whereas the effects of other organizations are context specific and vary based on neighborhood racial composition, commercial land use, and disadvantage.     

NEIGHBORHOOD DISADVANTAGE AND POLICE NOTIFICATION BY VICTIMS OF VIOLENCE*

This research uses data from the Area‐Identified National Crime Victimization Survey to examine the influence of neighborhood socioeconomic disadvantage on the likelihood of police notification by victims of violence. The results indicate that neighborhood disadvantage does not significantly affect the likelihood of police notification among robbery and aggravated assault victims. However, a significant curvilinear effect of neighborhood disadvantage is observed for simple assault victims. The implications of these results for community‐level crime research and for theoretical perspectives on police notification are discussed.     

Street Youth Crime: A Test of Control Balance Theory

Utilizing a sample of 400 homeless street youths, the paper explores the role control balance plays in the generation of crime. Using vignettes designed to represent violent crime, serious property crime, and minor property crime, the paper tests whether these youths sense of control over their poverty, shelter, hunger and other living conditions influences their participation in crime. Further, it examines how perceptions of risk and thrill, as well as deviant values, self‐control, deviant histories, and peer support impact on crime. Results indicate that both control deficits and control surpluses were related to assault and serious theft but not minor theft. Perceptions of thrill, deviant peers, deviant histories, and deviant values predicted violent and property crime, and perceptions of risk were related to the property offenses. Criminal peers also conditioned the impact of control surpluses and deficits on property offenses. Results are discussed in terms of future research and policy.     

Females' initiation into violent street crime

The present study is concerned with understanding when and how women become involved in violent street crime. Specifically, the study explores the correlates or explanatory factors of such offending in a sample of women arrested and/or incarcerated for violent street crimes in New York City. The findings suggest that an adequate understanding of female offending must consider the impact of neighborhood, peer, and addiction factors which affect both males' and females' participation in criminal violence. In addition, different configurations of these factors appear to contribute to the initiation of violent offending, depending on the age of onset. Early initiation into violent crime was accompanied by participation in a wide variety of other offending behaviors and deviant lifestyles. In contrast, those women who began their violent offending later did so in the context of a criminal career which, until the beginning of substance abuse, was more specialized and focused on typically nonviolent, gender-congruent activities (e.g., prostitution, shoplifting).     

REASSESSING NONLINEARITY IN THE URBAN DISADVANTAGE/VIOLENT CRIME RELATIONSHIP: AN EXAMPLE OF METHODOLOGICAL BIAS FROM LOG TRANSFORMATION*

Sociologists and criminologists have become increasingly concerned with nonlinear relationships and interaction effects. For example, some recent studies suggest that the positive relationship between neighborhood disadvantage and violent crime is nonlinear with an accelerating slope, whereas other research indicates a nonlinear decelerating slope. The present paper considers the possibility that this inconsistency in findings is partially caused by lack of attention to an important methodological concern. Specifically, we argue that researchers have not been sensitive to the ways in which logarithmic transformation of the dependent variable can bias tests for nonlinearity and statistical interaction. We illustrate this point using demographic and violent crime data for urban neighborhoods, and we propose an alternative procedure to log transformation that involves the use of weighted least‐squares regression, heteroscedasticity consistent standard errors, and diagnostics for influential observations.     

Gang Membership,Drug Selling,and Violence in Neighborhood Context

A prominent perspective in the gang literature suggests that gang member involvement in drug selling does not necessarily increase violent behavior. In addition it is unclear from previous research whether neighborhood disadvantage strengthens that relationship. We address these issues by testing hypotheses regarding the confluence of neighborhood disadvantage, gang membership, drug selling, and violent behavior. A three‐level hierarchical model is estimated from the first five waves of the 1997 National Longitudinal Survey of Youth, matched with block‐group characteristics from the 2000 U.S. Census. Results indicate that (1) gang members who sell drugs are significantly more violent than gang members that don’t sell drugs and drug sellers that don’t belong to gangs; (2) drug sellers that don’t belong to gangs and gang members who don’t sell drugs engage in comparable levels of violence; and (3) an increase in neighborhood disadvantaged intensifies the effect of gang membership on violence, especially among gang members that sell drugs.     

The Acute and Enduring Consequences of Exposure to Violence on Youth Mental Health and Aggression

The bulk of “neighborhood effects” research examines the impact of neighborhood conditions cross-sectionally. However, it is critical to understand whether the effects of neighborhood context are situational and whether they endure over time. In this study, we take seriously the notion that there are enduring consequences of exposure to deleterious neighborhood conditions. Using a rich set of longitudinal data on adolescents from the Project on Human Development in Chicago Neighborhoods, we estimate the effect of exposure to violence on both internalizing (depression and anxiety) and externalizing problems (aggression). We find that exposure to violence has both an acute and enduring effect on aggression, yet no effect on anxiety-depression, net of individual, family, peer, and neighborhood influences. Part of the enduring effect of violence exposure is explained by changes in social cognitions brought on by the exposure, yet much of the relationship remains to be explained by other causal mechanisms.     

WHEN IT'S GOOD TO BE “BAD”: VIOLENCE AND ADOLESCENT PEER ACCEPTANCE*

This article examines the relationship between adolescent violence and peer acceptance in school. Deriving hypotheses from subcultural theories of crime and violence, it tests whether the violence–status relationship varies across sociodemographic characteristics and educational contexts of students. Analyses of school network data collected from the National Longitudinal Study of Adolescent Health suggest that violence generally holds a negative relationship to peer friendship nominations for both males and females. However, for males, this effect varies by the educational standing of the students. Violence shows a modest positive association to peer acceptance for males who perform poorly in school. No evidence exists that race moderates the violence –status relationship. These findings are replicated in longitudinal analyses of a large metropolitan high school. For females, violence has a significant negative relationship to peer status that does not vary by individual characteristics. However, school levels of violence moderate the relationship between social status and female violence such that violent females have greater numbers of friendships in highly violent schools. The implications of these findings for peer research and delinquency theory are discussed.     

UNSTRUCTURED SOCIALIZING,COLLECTIVE EFFICACY,AND VIOLENT BEHAVIOR AMONG URBAN YOUTH*

Relying on extensions of routine activities and social disorganization theories, we examine whether 1) neighborhood social characteristics shape opportunities for the development of unstructured socializing with peers among adolescents, 2) whether unstructured socializing leads to an increase in violent behavior within urban communities, and 3) whether neighborhood collective efficacy modifies the impact of unstructured socializing on violence. The study outlined in this article uses three waves of data from the Project on Human Development in Chicago Neighborhoods Community Survey and Longitudinal Cohort Study. Results from multilevel linear models suggest that neighborhood collective efficacy supports the development of unstructured socializing with peers. Multilevel Rasch models of violent behavior indicate that, consistent with previous research, unstructured socializing is a powerful predictor of violence. Collective efficacy exerts an independent influence on violent behavior and attenuates the effect of unstructured socializing on this outcome.     

The role of young adolescents' perception in understanding the severity of exposure to community violence and PTSD

This study seeks to (a) identify and measure the lifetime exposure to community violence of 137 African American and Latino middle school students from a low income neighborhood and apply numerical weights to each violent event; (b) examine the relationship between the objective severity of child self reported violence exposure and the child's subjective perception of the most bothersome event; and (c) examine the relationship between child's exposure and posttraumatic stress disorder (PTSD). Results highlight that students' designation of their most bothersome exposure to community violence did not correspond to the most severe violent event they experienced. Regression analyses reveal the weight of the most severe event explains a larger percentage of the variance in PTSD compared with the relationship to victim, level of exposure, weight of the most bothersome exposure, and cumulative weight of all exposure. This study underscores the importance of assessing a child's perception of violent events.     

CRIME,FEAR, AND MENTAL HEALTH IN MEXICO

This article examines the effect of exposure to criminal violence on fear of crime and mental health in Mexico, a country that has experienced a dramatic rise in violent events resulting from the operation of drug trafficking organizations (DTOs). Data are drawn from more than 30,000 respondents to a national longitudinal survey of Mexican households. We use fixed‐effects models which allow us to control for time‐invariant individual and municipal characteristics affecting both exposure to violence and mental health. The results indicate a substantial increase in fear and psychological distress for individuals living in communities that suffered a rise in the local homicide rate even when exposure to other forms of victimization and more personal experiences with crime are taken into account. Because DTO killings occur in response to factors external to a specific neighborhood, they generate fear and psychological distress at a larger geographical scale. They also seem to create a generalized sense of insecurity, leading to increased fear of other types of crimes. We examine the effect of large surges in homicide and the presence of military and paramilitary groups combatting DTOs as these conditions may approximate those in conflict zones elsewhere in the world. We also explore differences in the relative sensitivity to homicide rates between sociodemographic groups.
