ECONOMIC INEQUALITY AND LEVELS OF HOMICIDE: AN ANALYSIS OF URBAN NEIGHBORHOODS*

This paper presents an analysis of the relationship between levels of economic inequality and homicide rates for a sample of 26 neighborhoods in Manhattan, New York. It argues that neighborhoods are more appropriate units of analysis for studying inequality and homicide than are larger political and statistical units because neighborhoods are more likely to constitute meaningful frames of reference for social comparisons. The principle hypothesis is that a high degree of economic inequality in a neighborhood will give rise to high levels of relative deprivation and high rates of homicide. The results of a series of multiple regression analyses fail to support this hypothesis. The measure of economic inequality is weakly associated with the observed homicide rates. Similarly, the racial composition of Manhattan neighborhoods exhibits no significant association with levels of homicide, given statistical controls for other sociodemographic variables. Two neighborhood characteristics do emerge as significant predictors of homicide rates: the relative size of the poverty population and the percent divorced or separated. Homicide rates tend to be highest in those neighborhoods characterized by extreme poverty and pervasive marital dissolution.     

EXPLORING THE INTERSEXUAL NATURE OF VIOLENT CRIMES*

Data on criminal homicides (from the Uniform Crime Reports) and aggravated assaults and simple assaults (from the National Crime Surveys) are analyzed to determine the extent to which violent crimes occur within or between sexes. The routine activities approach is used to develop hypotheses, and those hypotheses are tested using models that estimate the proportion of ingroup and outgroup crimes “expected.” With the exception of homicides, in which women murder men more often than expected, each of these violent crimes occurs within sexes more often than expected. There is a strong relationship between the type of violence (simple assault, aggravated assault, and homicide) and the extent to which the target of female aggression is a male.     

NEIGHBORHOOD INEQUALITY,COLLECTIVE EFFICACY,AND THE SPATIAL DYNAMICS OF URBAN VIOLENCE*

Highlighting resource inequality, social processes, and spatial interdependence, this study combines structural characteristics from the 1990 census with a survey of 8,872 Chicago residents in 1995 to predict homicide variations in 1996–1998 across 343 neighborhoods. Spatial proximity to homicide is strongly related to increased homicide rates, adjusting for internal neighborhood characteristics and prior homicide. Concentrated disadvantage and low collective efficacy—defined as the linkage of social control and cohesion—also independently predict increased homicide. Local organizations, voluntary associations, and friend/kinship networks appear to be important only insofar as they promote the collective efficacy of residents in achieving social control and cohesion. Spatial dynamics coupled with neighborhood inequalities in social and economic capacity are therefore consequential for explaining urban violence.     

NO COMMUNITY IS AN ISLAND: THE EFFECTS OF RESOURCE DEPRIVATION ON URBAN VIOLENCE IN SPATIALLY AND SOCIALLY PROXIMATE COMMUNITIES*

The link between resource deprivation and urban violence has long been explored in criminological research. Studies, however, have largely ignored the potential for resource deprivation in particular communities to affect rates of violence in others. The relative inattention is notable because of the strong theoretical grounds to anticipate influences that extend both to geographically contiguous areas and to those that, though not contiguous, share similar social characteristics. We argue that such influences—what we term spatial and social proximity effects, respectively—constitute a central feature of community dynamics. To support this argument, we develop and test theoretically derived hypotheses about spatial and social proximity effects of resource deprivation on aggregated and disaggregated homicide counts. Our analyses indicate that local area resource deprivation contributes to violence in socially proximate communities, an effect that, in the case of instrumental homicides, is stronger when such communities are spatially proximate. We conclude by discussing the implications of our findings for theories focused on community‐level social processes and violence, and for policies aimed at reducing crime in disadvantaged areas.     

A Test of Competing Hypotheses about Homicide Following Terrorist Attacks: An Interrupted Time Series Analysis of September 11 and Oklahoma City

There is substantial evidence that catastrophic events, including terrorist attacks, lead to increased levels of post-traumatic stress, especially in communities in close proximity to the incident. Some scholars also argue that these events disrupt social organization. On the other hand, many contend that these incidents produce social cohesion as community members coalesce to help each other in time of need. These ideas have resulted in competing hypotheses in the literature. The first is that violence will increase in the wake of catastrophic events due to heightened levels of individual stress and community disorganization. The second is that violence will decline after these events because of increased social cohesion, especially in the face of an outside threat. In order to test these competing hypotheses, we employed autoregressive integrated moving average (ARIMA) techniques to model the impact of the Oklahoma City bombing and the September 11 attacks on monthly homicide counts at the local, state, and national level. Unlike prior studies that provided evidence of an effect but did not use rigorous time-series techniques, we found no support for either of the competing hypotheses. We conclude that while such catastrophic events may have an effect on individual and collective efficacy well beyond the immediate impact of the incidents, these effects are not strong enough to influence homicide rates.

Using Social Media to Measure Temporal Ambient Population: Does it Help Explain Local Crime Rates?

A challenge for studies assessing routine activities theory is accounting for the spatial and temporal confluence of offenders and targets given that people move about during the daytime and nighttime. We propose exploiting social media (Twitter) data to construct estimates of the population at various locations at different times of day, and assess whether these estimates help predict the amount of crime during two-hour time periods over the course of the day. We address these questions using crime data for 97,428 blocks in the Southern California region, along with geocoded information on tweets in the region over an eight month period. The results show that this measure of the temporal ambient population helps explain the level of crime in blocks during particular time periods. The use of social media data appear promising for testing various implications of routine activities and crime pattern theories, given their explicit spatial and temporal nature.     

THE DECLINE OF ELITE HOMICIDE

Criminological research consistently shows that interpersonal homicide is largely confined to low-status people. Yet, anthropological and historical materials reveal that in earlier and simpler societies homicide was found throughout the status hierarchy. Using theory developed by Donald Black, I argue that a critical factor in the decline of lethal conflict among social elites is the increased availability of legal means of handling conflict. An implication is that since a focus on modern societies and their developed legal systems yields a limited and even distorted empirical picture of lethal violence, criminologists should strive to formulate theories that are cross-cultural and historical in scope.     

A TIME SERIES ANALYSIS OF VIOLENT CRIME AND ITS RELATION TO PROLONGED STATES OF WARFARE: THE ISRAELI CASE*

This study examines the effect of security-related stressors (e.g., wars and more prolonged states of belligerence) on violent crime patterns. Two alternative hypotheses are put forward: the cohesion hypothesis, which predicts a decrease in criminal violence in times of increased security-related stress, and the legitimation-habituation hypothesis, which predicts an increase in criminal violence in such periods. The study uses monthly data collected in Israel over 15 years. Security-related casualties and incidents are the security-related stressors, homicide and robbery are the measures of criminal violence, and economic and sociodemographic indicators are the control variables. The analysis uses a multiple regression model with autoregressive errors. The reported number of casualties had a significant marginal positive effect on homicide, thus supporting the legitimation-habituation hypothesis. Such an effect could not be detected for the robberies series. Inflation increments had a strong positive effect on both series, and rates of unemployment had a significant marginal positive effect on robbery but not on homicide. The effects of the various stressors are not contemporaneous but extend to several months ahead. Some theoretical aspects of the findings and their implications for Israeli society are discussed.     

“命案必破”的逻辑解析

“命案必破”是一个规范命题,承诺命题,同时又是一个必然模态命题。“命案必破”之因,产生了公安工作发展之果;公安工作发展之果又不断促进“命案必破”目标的实现;“命案必破”目标的不断实现必然促进社会治安秩序的稳定;社会治安秩序的稳定又为构建社会主义和谐社会提供强有力的保障。因此,无论从逻辑上对命题本身的解读,还是对命题与实践结果的因果分析,都可以得出一个结论,“命案必破”命题的提出不但是科学的,而且具有十分积极的社会意义。     

VICARIOUS HOMICIDE VICTIMIZATION AND SUPPORT FOR CAPITAL PUNISHMENT: A TEST OF BLACK'S THEORY OF LAW*

This article examines the relationship between experiencing the homicide of a family member, friend, or acquaintance and the likelihood of support for capital punishment. Homicide victims'family and friends are often portrayed as strong advocates of the death penalty. Yet, the effect of vicarious homicide victimization on support for capital punishment has never been systematically examined, and in fact, Donald Black's theory of law suggests an inverse relationship between the two variables. Using data from the 1988 General Social Survey, this research tests hypotheses derived from Black's theory regarding the relationship among social intimacy, cultural status, and the use of law in response to conflict. Multivariate logistic regression models suggest that the experience of personally knowing a homicide victim significantly affects one's likelihood of support for the death penalty, but the effect of vicarious victimization varies for black and white respondents. The empirical patterns indicate that in addition to race, religious orientation and gender also play important roles in determining the relationship between vicarious homicide victimization and support for the death penalty.     

Intimate homicide between Asians and non-Asians: the impact of community context

This study tests two competing hypotheses regarding the social structural dynamics of intimate homicide: backlash versus collective efficacy. This study also examines the role of race in how social factors specified in each hypothesis affect intimate homicide. Data are from the California Vital Statistics and Homicide Data, 1990-1999. Results from a negative binomial regression partially support both hypotheses. In terms of magnitude, social deprivation is more important than both the backlash and collective efficacy factors. Asian intimate homicide is susceptible to the ability of communities to resolve commonly identified problems, whereas non-Asian intimate homicide is vulnerable to the depletion of socioeconomic resources. Implications of these findings are discussed in this article.     

VARIATION IN AFRICAN-AMERICAN HOMICIDE RATES: AN ASSESSMENT OF POTENTIAL EXPLANATIONS*

Using 1990 data for 222 metropolitan areas, this study extends the traditional variables examined in models of homicide and uses regression analysis to test the viability of three alternative theories that may explain high rates of African-American homicide victimization. The first approach examines the extent to which weak forms of social control have contributed to high homicide rates. The second approach tests the notion that discrimination and inequality have increased levels of absolute and relative deprivation for blacks, which in turn engender frustration and contribute to higher levels of violence. The third approach posits that engagement in violent activity may be a rational act for young African-American males faced with the reality of highly limited economic opportunities. While all three approaches contribute to explaining high African-American homicide, this study shows the greatest support for the social control explanation.     

Infant Homicide: Victim/Offender Relationship and Causes of Death

The phenomenon of infant homicide (infanticide) has been examined, explained, justified, and treated according to physiological, psychiatric, and psychological correlates. There has been little examination of the social correlates directly pertaining to infant homicide. However, social correlates are often indirectly addressed in the medical and psychiatric literature. This paper tests relationships between social correlates often asserted, but typically not tested, in the medical and psychiatric literature. Using a sample of 380 infant homicides in Texas from 1981 through 1991, a multivariate analysis between victim/offender relationship, cause of death, and victim's age at time of fatal injury, predicts the age at which an infant (34 months) is likely to be fatally injured. The findings support the following hypotheses: (1) as the age of the victim increases, the level of violence used to fatally injure the infant increases; and (2) as the level of relational intimacy decreases, the level of violence used to fatally injure the infant increases.     

The Role of Immigration: Race/Ethnicity and San Diego Homicides Since 1970

Objectives

The temporal variation in homicide is examined by studying trends in race/ethnic specific killings (e.g. Blacks, Latinos and Whites). Two substantively important issues are also addressed—a closer examination of the role community heterogeneity plays in homicide levels and the treatment of immigration as an endogenous social process.

Methods

Data are reported homicides in the city of San Diego, California over the period 1960–2010. The address of each killing is geocoded into 341 census tracts.

Results

We find that neighborhoods experiencing increases in the foreign-born population tend to be less violent. White and Latino homicide victimization was reduced significantly as a product of increases in the neighborhood concentration of foreign-born individuals. Supplementary analyses did not find empirical evidence that the influx of foreign-born individuals could (or should) be considered a disruptive social process. Over the past five decennial census periods, the exponential increase in immigration in this border city is not associated with an increase in homicide victimization.

Conclusions

When examined through a wider temporal lens than is typically employed, and accounting for the endogeneity of immigrant residential settlement, we find no support for the claims that immigration is a crime generating social process.

     

The Role of Lifestyle and Personal Characteristics on Fear of Victimization among University Students

The fear of crime has been both theoretically and empirically connected to a complex relationship of situational context (e.g., time of day, location) and personal characteristics (e.g., age, race, gender, personal and vicarious victimization). Building off of routine activities and lifestyle-exposure theory, this research extends the understanding of these relationships by examining the impact of lifestyle activities (e.g., consumption of alcohol, illicit drugs, and time away from residence) and personal characteristics (e.g., direct and vicarious victimization) on the fear of various crimes across temporal situations, among a sample of college and university students. The results indicate that fear of crime varies by crime type and that certain demographic and lifestyle characteristics and experiences with victimization affect students?? fear of crime. Although no evidence was found to suggest that fear of theft varies by temporal context (i.e., during the day or at night), certain characteristics, such as gender, perceived risk, and avoidance behaviors, have varying relationships with fear of violent crimes when considering time of day. The findings suggest that future research should examine more critically the relationship that lifestyles, personality, gender, and time of day have with the fear of crime.     

POPULATION DIVERSITY AND CROSS-NATIONAL HOMICIDE: THE EFFECTS OF INEQUALITY AND HETEROGENEITY*

This study examines the impact of income inequality and ethnic heterogeneity on homicide rates for a sample of 32 nations. The results of the analyses indicate that vertical social direrentiation, as measured by income inequality, and horizontal differentiation, as indexed by ethnic heterogeneity, have signijicant main effects on cross-national homicide. Additionally, evidence is presented suggesting an interaction effect on inequaliry and heterogeneity on homicide. It appears that increased ethnic heterogeneity exacerbates the impact of income inequality on homicide rates.     

Poverty, Inequality, and City Homicide Rates

Messner's recent investigation of homicide and relative and absolute economic deprivation is replicated here, but cities rather than SMSA's and three years (1950, 1960, 1970) rather than one (1970) are considered. Because of tremendous intra-unit variation for SMSAs with respect to homicides and sociodemographic characteristics (an important variation that is masked when data are aggregated on a SMSA level), cities are a preferable unit of analysis in cross-sectional investigations of homicide. Where M e s m found a significant negative relationship between percentage of poverty (absolute deprivation) and homicides, I consistently find the opposite pattern as predicted. In both studies, however, there is only a slight and nonsignificant relationship between relative economic deprivation (income inequality) and homicides. Unlike Messner, however, I do not consider this finding surprising. At best, there is only a weak theoretical linkage between homicide and relative economic deprivation. Accordingly, the results of this investigation for both absolute and relative deprivation are neither "perplexing" nor do they warrant the "serious reconsideration of the linkages between poverty, inequality and the homicide rate" that Messner (1982: 112) calls for.     

Social support and homicide in transitional Russia

Like the United States, Russia is a large industrialized nation with high violence rates. Although its overall homicide rate is among the highest in the world, however, local rates of crime vary widely. Similarly, the level of social support provided by the state varies throughout Russia due to former Soviet policies, the differential pace of political and economic change, and the level of development. Relying upon recent criminological literature on social support theory, this study tested the hypotheses that areas with higher levels of social support will have lower homicide rates and that the effects of negative socioeconomic change on homicide rates will be moderated by levels of social support. Utilizing data from Russian regions (n = 78) and controlling for other structural covariates, negative binomial regression was employed to estimate the effects of social support on regional homicide rates. As expected, negative socioeconomic change was associated with higher homicide rates, but the results provided no support for direct or conditioning effects of social support on homicide. The findings are discussed in the context of Russia-specific conditions and of the meaning of these findings for recent research on social support and crime.     

Homicides--the sociodemographic background of the offender and the behavioral symptoms

The authors examined 261 forensic-psychiatric reports to determine whether persons convicted of criminal homicide differed from persons convicted of other crimes with regard to personal biography, sociodemographic milieu, and character traits. Both groups were found to come from similarly disadvantaged social backgrounds. Murderers could not be distinguished on the basis of biographical data alone. The parameters found to be distinctive of murderers were: site of the crime, criminal-victim relationship, motive for the act, intoxication at the time of the crime, and the perpetrator's opinion regarding the purpose and intent of the homicide. The present findings confirm some of the results obtained by other authors on this topic.     

A METHODOLOGICAL ADDITION TO THE CROSS‐NATIONAL EMPIRICAL LITERATURE ON SOCIAL STRUCTURE AND HOMICIDE: A FIRST TEST OF THE POVERTY‐HOMICIDE THESIS*

Dozens of cross‐national studies of homicide have been published in the last three decades. Although nearly all these studies test for an association between inequality and homicide, no studies test for a poverty—homicide association. This absence is disconcerting given that poverty is one of the most consistent predictors of area homicide rates in the abundant empirical literature on social structure and homicide in the United States. Using a sample that coincides closely with similar recent studies, applying a proxy for poverty (infant mortality) that is commonly employed in noncriminological cross‐national research, and controlling for several common covariates (including inequality), this study provides the first test of the poverty—homicide hypothesis at the cross‐national level. The results reveal a positive and significant association between a nation's level of poverty and its homicide rate. The findings also suggest that we may need to reassess the strong conclusions about an inequality—homicide association drawn from prior studies, as this relationship disappears when poverty is included in the model.
