Urban greenspace (UGS) has been recently linked to public safety. Criminologists, however, have been largely absent from the discussion about this association, despite having important theoretical tools and empirical findings to contribute. In the current study, we review the prominent criminological perspectives that may be used to explain the association between UGS and crime. Furthermore, we draw from prior work to extend beyond the question of whether UGS affects crime to the more crucial question of when it does. Using a sample of block groups in Washington, D.C., we examine the association between two measures of UGS—tree canopy coverage and noncanopy vegetation coverage—and violent and property crime. We also assess the moderating effects of antecedents to social disorganization (poverty and homeownership) on the association between UGS and crime. Our results suggest that both types of UGS are associated with fewer crimes, even while controlling for a range of criminogenic factors. The effects of tree canopy coverage appear to be crime general, while the effects of noncanopy vegetation coverage only apply to violent crime. The effects of tree canopy, however, are weaker in communities characterized by high levels of poverty and low levels of homeownership. [ABSTRACT FROM AUTHOR]

Whereas existing ecology of crime research frequently uses a cross-sectional design, an open question is whether theories underlying such studies will operate similarly in longitudinal research. Using latent trajectory models and longitudinal data in half-mile egohoods from the Southern California region over a 10-year period (2000–2010), we explore this question and assess whether the changes in key measures of social disorganization theory are related to changes in violent or property crime through three possible relationships: 1) a monotonic relationship, 2) an asymmetric relationship, and 3) a perturbation relationship in which any change increases crime. We find evidence that measures can exhibit any of these three possible relationships, highlighting the importance of not assuming monotonic relationships. Most frequently observed are asymmetric relationships, which we posit are simultaneously capturing more than one theoretical process of neighborhoods and crime. Specific findings include asymmetric relationships between change in concentrated disadvantage, racial/ethnic minority composition, or population and violent crime, as well as relationships between change in Asian composition or population and property crime. We consider how this strategy opens a needed area of future research assessing how measures for other theories operate as environments change.

Social disorganization theory holds that neighborhoods with greater residential stability, higher socioeconomic status, and more ethnic homogeneity experience less disorder because these neighborhoods have higher social cohesion and exercise more social control. Recent extensions of the theory argue that disorder in turn affects these structural characteristics and mechanisms. Using a data set on 74 neighborhoods in the city of Utrecht in the Netherlands spanning 10 years, we tested the extended theory, which to date only a few studies have been able to do because of the unavailability of neighborhood-level longitudinal data. We also improve on previous studies by distinguishing between the potential for social control (feelings of responsibility) and the actual social control behavior. Cross-sectional analyses replicate earlier findings, but the results of longitudinal cross-lagged models suggest that disorder has large consequences for subsequent levels of social control and residential instability, thus leading to more disorder. This is in contrast to most previous studies, which assume disorder to be more a consequence than a cause. This study underlines the importance of longitudinal data, allowing for simultaneously testing the causes and consequences of disorder, as well as the importance of breaking down social control into the two dimensions of the potential for social control and the actual social control behavior. © 2011 American Society of Criminology.

Social disorganization theory holds that neighborhoods with a greater population stability, higher socio-economic status and more ethnic homogeneity experience less disorder because these neighborhoods have higher social cohesion and exercise more social control. Recent extensions of the theory argue that disorder in turn affects these structural characteristics and mechanisms. Using a dataset on 74 neighborhoods in the city of Utrecht in the Netherlands spanning ten years, we tested the extended theory, which to date only few studies have been able to do because of unavailability of neighborhood-level longitudinal data. We also improve on previous studies by distinguishing between potential for social control (feelings of responsibility) and actual social control behavior. Cross-sectional analyses replicate earlier findings, but the results of longitudinal cross-lagged models suggest that disorder has large consequences for subsequent levels of social control and population turnover, thus leading to more disorder. This is in contrast to previous research, which sees disorder more as a consequence than a cause. This study underlines the importance of longitudinal data, allowing for simultaneously testing the causes and consequences of disorder, as well as the importance of breaking down social control into the potential for social control and actual social control behavior.

By drawing on the work of Jacobs (1961), we hypothesize that public contact among neighborhood residents while engaged in day-to-day routines, captured by the aggregate network structure of shared local exposure, is consequential for crime. Neighborhoods in which residents come into contact more extensively in the course of conventional routines will exhibit higher levels of public familiarity, trust, and collective efficacy with implications for the informal social control of crime. We employ the concept of ecological ('eco-') networks-networks linking households within neighborhoods through shared activity locations-to formalize the notion of overlapping routines. By using microsimulations of household travel patterns to construct census tract-level eco-networks for Columbus, OH, we examine the hypothesis that eco-network intensity (the probability that households tied through one location in a neighborhood eco-network will also be tied through another visited location) is negatively associated with tract-level crime rates ( N = 192). Fitted spatial autoregressive models offer evidence that neighborhoods with higher intensity eco-networks exhibit lower levels of violent and property crime. In contrast, a higher prevalence of nonresident visitors to a given tract is positively associated with property crime. The results of these analyses hold the potential to enrich insight into the ecological processes that shape variation in neighborhood crime. [ABSTRACT FROM AUTHOR]

Nearly one million people were killed in the Rwandan genocide in 1994. Although scholars have theorized why this violence occurred, we know comparatively less about how it unfolded. Accordingly, this article assesses the determinants of subnational levels of killing in 142 Rwandan communes by relying on data from the Rwandan Ministry of Local Administration and Community Development, the National University of Rwanda, and the 1991 Rwandan census. Fixed effects analyses reveal that top-down and bottom-up factors coalesced to influence violence across Rwanda. The state orchestrated and implemented the violence, and more violence occurred near the extremist center of the country as well as where state actors met strong opposition. Local conditions also shaped the violence, however, and indicators of low community cohesion and social control are associated with comparatively more violence. When put together, a unique model is introduced that integrates state conflict theories and social control theories of crime to explain subnational killing during the genocide in Rwanda.

Social disorganization theory argues that racial/ethnic heterogeneity is a key neighborhood characteristic leading to social disorganization and, consequently, higher levels of crime. Heterogeneity's effect is argued to be a result of its fragmentation of social ties along racial/ethnic lines, which creates racially homophilous social networks with few ties bridging racial/ethnic groups. Most studies of social ties in social disorganization models, however, have examined their quantity and left unaddressed the extent to which ties are within or across different racial groups. This study goes beyond previous studies by examining the effects of both racially homophilous and interracial friendship networks on informal social control. Using multilevel models and data from 66 neighborhoods with approximately 2,300 respondents, we found that heterogeneity actually increased the average percentage of residents with interracial friendship networks, but the percentage of residents with interracial networks decreased the likelihood of informal social control. In contrast, the percentage of residents with White racially homophilous networks increased the likelihood of informal social control. Examining the microcontext of individuals' networks, however, we found residents with interracial ties reported higher likelihoods of informal social control and that this effect was enhanced in neighborhoods with higher percentages of non-White racially homophilous networks.

Defining 'neighborhoods' is a bedeviling challenge faced by all studies of neighborhood effects and ecological models of social processes. Although scholars frequently lament the inadequacies of the various existing definitions of 'neighborhood,' we argue that previous strategies relying on nonoverlapping boundaries such as block groups and tracts are fundamentally flawed. The approach taken here instead builds on insights of the mental mapping literature, the social networks literature, the daily activities pattern literature, and the travel to crime literature to propose a new definition of neighborhoods: egohoods. These egohoods are conceptualized as waves washing across the surface of cities, as opposed to independent units with nonoverlapping boundaries. This approach is illustrated using crime data from nine cities: Buffalo, Chicago, Cincinnati, Cleveland, Dallas, Los Angeles, Sacramento, St. Louis, and Tucson. The results show that measures aggregated to our egohoods explain more of the variation in crime across the social environment than do models with measures aggregated to block groups or tracts. The results also suggest that measuring inequality in egohoods provides dramatically stronger positive effects on crime rates than when using the nonoverlapping boundary approach, highlighting the important new insights that can be obtained by using our egohood approach.

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.

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. [ABSTRACT FROM AUTHOR]

Emerging research associated with the “immigration revitalization” perspective suggests that immigration has been labeled inaccurately as a cause of crime in contemporary society. In fact, crime seems to be unexpectedly low in many communities that exhibit high levels of the following classic indicators of social disorganization: residential instability, ethnic heterogeneity, and immigration. But virtually all research conducted to date has been cross-sectional in nature and therefore unable to demonstrate how the relationship between immigration and crime might covary over time. This limitation is significant, especially because current versions of social disorganization theory posit a dynamic relationship between structural factors and crime that unfolds over time. The current study addresses this issue by exploring the effects of immigration on neighborhood-level homicide trends in the city of San Diego, California, using a combination of racially/ethnically disaggregated homicide victim data and community structural indicators collected for three decennial census periods. Consistent with the revitalization thesis, results show that the increased size of the foreign-born population reduces lethal violence over time. Specifically, we find that neighborhoods with a larger share of immigrants have fewer total, non-Latino White, and Latino homicide victims. More broadly, our findings suggest that social disorganization in heavily immigrant cities might be largely a function of economic deprivation rather than forms of “neighborhood” or “system” stability.

The impact of residential turnover and compositional change at the neighborhood level on local patterns of crime lies at the center of most ecological studies of crime and violence. Of particular interest is how racial and ethnic change impacts intragroup and intergroup crime. Although many studies have examined this effect using city-level data, few have evaluated it using neighborhood-level data. Using incident-level data for the South Bureau Policing Area of the Los Angeles Police Department aggregated to census tracts, we use a novel methodology to construct intragroup and intergroup rates of robbery and assaults. The South Bureau has experienced dramatic demographic change as it has transitioned from a predominately African-American area to a predominately Latino area. We find support for the social disorganization model, as racial/ethnic transition in nearby tracts leads to greater levels of intergroup violence by both groups as well as to more intragroup violence by Latinos. Such neighborhoods seem to experience a breakdown in norms, which leads to higher levels of violence in all forms. Particularly noteworthy is that intragroup crime is highest in all settings, which includes the most heterogeneous tracts. We also find support for the consolidated inequality theory, as greater inequality across the two groups leads to more violence by the disadvantaged group. [ABSTRACT FROM AUTHOR]

Americans move frequently, and moving alters their risks of victimization. This study uses unique longitudinal, multilevel data from the 1980–1985 National Crime Survey to examine the effects of residential turnover on household victimization. The two major findings of the study are as follows: First, housing turnover is a transition that independently increases the risk that a dwelling will experience a crime. This finding is true even controlling for persistent differences in crime vulnerability between dwellings. Second, changes in the composition and routine activities of households also alter the risks of victimization. These findings provide support for social disorganization and crime opportunity theories. [ABSTRACT FROM AUTHOR]

Informal social control is a central concept in the contemporary social disorganization literature, and much attention has been directed at examining community characteristics related to variation in the quantity of informal social control across communities. However, considerably less attention has been paid to variation in forms of informal social control. This study examines the extent to which neighborhood characteristics are related to residents’ likelihood of using two different forms of informal social control: direct informal social control (i.e., through direct intervention) and indirect informal social control (i.e., through mobilizing formal authorities). Data for this study are based on surveys of residents in 66 neighborhoods. The analysis uses hierarchical modeling to examine whether neighborhood characteristics central to contemporary social disorganization theory have similar effects on these two forms of neighborhood social control. Findings indicate that social ties increase the likelihood of direct informal social control but not indirect informal social control, whereas social cohesion and trust decreases indirect informal social control but does not have a significant effect on direct informal social control. Faith in the police is not found to affect either form of informal social control. These findings are discussed in terms of current issues in contemporary social disorganization theory.

In this paper, we examine and compare the impact of social disorganization, including recent immigration, and other predictors on community counts of black and Latino motive-specific homicides in Miami and San Diego. Homicides for 1985 to 1995 are disaggregated into escalation, intimate, robbery and drug-related motives. Negative binomial regression models with corrections for spatial autocorrelation demonstrate that there are similarities and differences in effects of social disorganization and other predictors by motive-specific outcomes, as well as for outcomes across ethnic groups within cities and within ethnic groups across cities. Recent immigration is negatively or not associated with most outcomes. Overall, the study shows the importance of disaggregating homicide data by race/ethnicity and motive and demonstrates that predictions based on existing theories are qualified on local conditions.

Why do youth in structurally disadvantaged neighborhoods experience lower levels of informal social control? To answer this question, we examined multilevel data from the Project on Human Development in Chicago Neighborhoods. Using hierarchical regression, we found that (1) neighborhood attachment and satisfaction with police contributed significantly to neighborhood levels of informal social control; and (2) neighborhood attachment and satisfaction with police mediated a substantial portion of the association between informal social control and neighborhood levels of concentrated disadvantage and immigrant concentration.

This article applies an individual-level routine activities perspective to explaining rates of delinquency. The theoretical analysis also links the opportunity processes of that perspective to key themes of social disorganization theory. Multilevel analyses of 4,358 eighth-grade students from thirty-six schools in ten cities support the central hypothesis: Time spent in unstructured socializing with peers has both individual and contextual effects that explain a large share of the variation in rates of delinquency across groups of adolescents who attend different schools. In addition, parental monitoring has a very strong contextual effect on unstructured socializing, which supports the proposed integration of routine activity and social disorganization perspectives.

Japan has long been recognized for its low rates of violent crime, rates that usually seem to be declining. The most common explanation for postwar rates links unique cultural characteristics to a system of exceptionally effective informal social controls that, at the macro level, suggest low levels of social disorganization. Other common explanations include low levels of economic stress, a small proportion of young males and a criminal justice system that delivers a high certainty of punishment. In this paper we test these four explanations for Japanese trends using both an annual time-series national analysis (1951 to 2000) and a pooled cross-sectional time-series analysis of the 47 Japanese prefectures from 1955 to 2000 (at 5-year intervals). The results from the two analyses are largely congruent. They show that measures of economic stress, certainty of punishment and age structure are — compared to common social disorganization measures — more consistent predictors of Japanese postwar violent crime trends. Our results suggest that the remarkable strength of the postwar Japanese economy may play a larger role in explaining Japanese violent crime rates than is usually recognized. [ABSTRACT FROM AUTHOR]

Recent research has begun to examine the effects of politics on crime. However, few studies have considered how local political variation is likely to affect crime. Using insights from urban politics research, this paper develops and tests hypotheses regarding direct and conditional effects of local politics on violent crime in 958 cities in 1991. Results from negative binomial regression analyses show that violent crime rates vary by local political structures and the race of the mayor. In addition, the effects of structural factors such as poverty, unemployment, and female-headed households on violent crime depend on local form of government and the number of unreformed local governmental structures. Implications for systemic social disorganization and institutional anomie theories are discussed. [ABSTRACT FROM AUTHOR]

Current criminological research rooted in social disorganization theory has primarily focused on structural disorganization and has largely ignored the role of cultural disorganization. This paper develops the theoretical role of cultural disorganization in the contemporary social disorganization model, integrating aspects of both the systemic model and a cultural attenuation model. This model is empirically examined using structural equation modeling. Survey data from residents in 66 neighborhoods in a Southern state provide the primary data. In part, the findings show that concentrated disadvantage and the level of social ties affect cultural strength, which in turn significantly affects informal social control. These findings demonstrate the relevance of weakened culture in explaining informal social control and call for further theoretical expansion of social disorganization models to include cultural disorganization.

The present study examined whether variations in social ecological conditions in New York City police precincts and divisions have predicted patterns of police misconduct from 1975 to 1996. The study included misconduct cases involving bribery, extortion, excessive force, and other abuses of police authority, as well as certain administrative rule violations. Using a longitudinal framework, the analyses found that dimensions of structural disadvantage and population mobility-drawn from the social disorganization literature—as well as changes in Latino population—drawn from the racial conflict perspective—explained changes in police misconduct over time. Further, most of the variations occurred within, as opposed to between, precincts and divisions over time, strengthening the case for a longitudinal examination. [ABSTRACT FROM AUTHOR]

Prior studies of violence among individuals with mental illnesses have focused almost exclusively on individual-level characteristics. In this study, I examine whether the structural correlates of neighborhood social disorganization also explain variation in violence. I use data on 270 psychiatric patients who were treated and discharged from an acute inpatient facility combined with tract-level data from the 1990 U.S. Census. I find that living in a socially disorganized neighborhood increased the probability of violence among the sample, an effect that was not mediated by self-reported social supports. Implications for future research in the areas of violence and mental illness are discussed. [ABSTRACT FROM AUTHOR]

Attempts to integrate the two predominant spatial theories of crime, social disorganization and routine activity theories, may benefit from examining empirical relationships at units of analysis smaller than the relatively large units characteristic of most ecological research (cities, SMSAs, census tracts, multiple city blocks). Small units of analysis, specifically, face blocks (both sides of a city block between two intersections) are analyzed in a study of street robbery within a medium-size southeastern U.S. city. Models of street robbery and street-robbery "potential" suggest a crime diffusion process. Several interaction effects between variables of social disorganization and routine activity theory are found, which may form the basis in future research for successful theoretical integration.

In order to extend the study of community social disorganization and crime beyond its exclusive focus on large urban centers, we present an analysis of structural correlates of arrest rates for juvenile violence in 264 nonmetropolitan counties of four states. Findings support the generality of social disorganization theory: Juvenile violence was associated with rates of residential instability, family disruption, and ethnic heterogeneity. Though rates of poverty were not related to juvenile violence, this is also in accord with social disorganization theory because, unlike urban settings, poverty was negatively related to residential instability. Rates of juvenile violence varied markedly with population size through a curvilinear relationship in which counties with the smallest juvenile populations had exceptionally low arrest rates. Analyses used negative binomial regression (a variation of Poisson regression) because the small number of arrests in many counties meant that arrest rates would be ill suited to least-squares regression.

This article explores the role of place managers in controlling drug and disorder problems on 100 street blocks in Oakland, California. We use self-reports from a sample of place managers to explore their role in changing the social and physical conditions of street-block activity within the context of a randomized field trial in Oakland. On-site observations of the changes in the social and physical conditions of 100 street blocks were conducted and used as our outcome measures. Our results suggest that street blocks where place managers engaged in collective crime control activities had significantly fewer signs of disorder and greater levels of civil behavior. Our results also show that community cohesiveness on a street block was associated with fewer males selling drugs. [ABSTRACT FROM AUTHOR]

This study examines social disorganization theory using calls to the police during 1980 in 60 Boston neighborhoods. These data, based on complainant reports of crime rather than official police reports, allow further investigation of differences in findings based on victimization data and official crime data. The rates of assault, robbery, and burglary are regressed on poverty, mobility, racial heterogeneity, family disruption, and structural density. Interaction terms for poverty and heterogeneity, poverty and mobility, and mobility and heterogeneity are also explored. Results from this study support findings from recent victimization studies and earlier ecological studies using official counts of crime. Poverty and heterogeneity, along with family disruption and structural density, are found to be important ecological variables for understanding the distribution of crime rates among neighborhoods.

Several theoretical approaches (e.g., psychoanalytic theory, learning theory, and social-disorganization) have led criminologists to the belief that harmony in family life prevents delinquency, while disharmony promotes it. Moreover, several studies suggested that there is interaction between the functioning of the family and social class as causes of delinquency. The present study of 414 Israeli adolescents reveals neither interaction between family relationships and social class, nor any substantive main effect, suggesting that (1) Israel's social conditions render the family a relatively less important role as a crimogenic agent, and (2) that family life has previously been idealized, and their role exaggerated due to the theoreticians' value bias.

This article reports that the U.S. National Clearinghouse for Mental Health Information has issued a comprehensive listing of the literature on the causes, effects and responses to urban disorders. The 2,279 items, published primarily during 1954-1968, are concerned with racial riots and racially motivated social disorders in the U.S. rioting and disorders of a nonracial nature, minority groups, civil rights, the nation's response to conditions of poverty and social disorder, and individual violence.
