Using the National Incident-Based Reporting System (NIBRS) to Test Estimates of Arrestee and Offender Characteristics

National-Incident Based Reporting System (NIBRS) information for 1993 iscompared with two other sets of homicide data to assess the acuracy ofprocedures for estimating age-, sex-, and race-specific arrest counts fromtraditional Uniform Crime Report (UCR) data. The simultaneous age, race, andsex characteristics of offenders provided in the NIBRS arrest and offender segmentsare compared with estimates of the same characteristics derived from summaryUCR arrest data. The results suggest that using UCR marginal totals toestimate arrest counts by race and sex produces reasonably accurateestimates of the number of black and nonblack male arrests for murder andother offenses. Estimates of arrests of females by race and sex are lessaccurate, probably because of the relatively small number of arrests ofwomen and girls. Estimating male arrest counts for specific age groups alsoproduces reasonably accurate estimates. The results suggest that previousresearch employing such estimates may have been misleading in the estimatesof female arrests by race but accurate in the estimates of male arrests byrace. Although the use of summary UCR-based estimates in futurecross-sectional research will become increasingly unnecessary as the NIBRSreplaces the current UCR program, time series research designs on arrest andcrime trends will continue to require estimates.     

Methods for Understanding and Analyzing NIBRS Data

The National Incident-Based Reporting System (NIBRS) is an incident-basedcrime reporting program for local, state, and federal law enforcementagencies. Within each criminal incident, NIBRS captures information onoffenses, victims, offenders, property, and persons arrested, as well asinformation about the incident itself. The ability to link and analyze thisdetailed information is a significant improvement to the existing UniformCrime Reporting (UCR) summary reporting system. As one might expect,however, this increase in crime data significantly complicates the life ofthe data analyst, particularly when cross tabulating the NIBRS data. To dealwith the complexity of NIBRS data, one must understand its structure. Thisarticle provides an overview of the NIBRS structure and methods formaneuvering within it to present and interpret correctly cross tabulationsof the NIBRS data.     

Using National Incident-Based Reporting System Data for Strategic Crime Analysis

The utility of the National Incident-Based Reporting System (NIBRS) forstrategic crime analysis has yet to be explored. The NIBRS represents anadvancement over existing reporting systems and possesses considerableutility to frontline law enforcement with respect to strategic crimeanalysis. This paper discusses the utility of the NIBRS for identifyinglocal and regional trends in narcotics related offenses. As an example, weselected four localities from the 1997 Virginia NIBRS data to examine trendsin the sale/distribution and possession of narcotics. Our analysis showsthat the NIBRS provides significantly more incident-related detail than hasheretofore been available for strategic crime analysis at the regional orstate level. Moreover, the NIBRS provides neighboring communities theopportunity to compare information on emerging crime patterns and criminalenterprises which extend beyond local boundaries. Finally, enhancing localreporting compliance by highlighting the strategic utility of the data tolocal law enforcement will ultimately ensure the quality of the data set,which can then be employed by larger entities as well as criminal justiceresearchers for policy development and planning.     

School-related victimizations among adolescents: An analysis of National Crime Survey (NCS) narratives

This paper uses a heretofore untapped source of information in the National Crime Survey (NCS) victimization data—the interviewer narratives—to explore school-related victimizations among adolescents. These narrative reports provide important information bearing on lifestyle and routine activity theories of victimization that is simply not available from the more familiar, highly structured portions of the NCS questionnaire. The NCS narratives suggest that a large proportion of school-related victimizations stems from peer interactions that occur in the course of routine daily activities and escalate into victimizations. Students represent pools of both potential offenders and potential victims who come in frequent contact with each other, often in the absence of capable guardians. However, rather than predatory, calculated attempts to harm, school-related victimizations among adolescents appear to consist primarily of bullying, injured pride, and misguided mischief. The theoretical and methodological implications of this study are highlighted.     

The National Incident-Based Reporting System: Research and Policy Applications

The National Incident-Based Reporting System (NIBRS) offers a new source ofdata for measuring crime. Though far from national in coverage, NIBRS datacan address research and policy questions outside the scope of the UniformCrime Reports and the National Crime Victimization Survey. Comparisons ofthe three sources of crime data are presented, with particular emphasis onwhat can be learned from incident-based police data that cannot be learnedfrom other sources. Like all data on crime, the NIBRS is subject to variousproblems with validity and measurement error. Two general categories of suchproblems are discussed: those evident in the design of the NIBRS and thoselinked to more general issues in the organizational production of data.     

Discretion and the Sex Dyad: Exploring the Interactive Effects of Offender and Victim Sex on Reporting and Arrest of One-on-One Assaultive Crime

Gender has been hypothesized to affect how violent offenders are treated within the criminal justice system, but studies have tended to ignore the role of the victim in decision making. This study explores the interactive effects of offender and victim sex (i.e., the sex dyad) on reporting and arrest of one-on-one assaultive crime. Using data from the National Crime Victimization Survey and National Incident-Based Reporting System, findings show that male-on-female offenses are reported to police more often than other dyads, but female-on-male offenses result in more arrests. Meanwhile, female-on-female offenses result in fewer arrests, despite nonsignificant differences in reporting. Implications of findings for theory and future research on gender discretion are discussed.     

DISTINCTIVE CHARACTERISTICS OF ASSAULTS MOTIVATED BY BIAS*

This research examines the ways in which assaults motivated by bias are similar to and different from other types of assault. Analyses are based on data from the National Incident Based Reporting System (NIBRS), pooled across eleven states. We find evidence suggesting that offenders motivated by racial and ethnic bias are more likely to be versatile offenders than specialists: they are more (not less) likely to be using drugs and alcohol during the crime than conventional offenders. Bias offenders are also more likely to seriously injure the victim. Finally, we find that the risks of bias crime victimization (relative to the risk of assault victimization generally) are similar for blacks and other racial minorities.     

Stereotypical Hate Crimes and Criminal Justice Processing: A Multi-Dataset Comparison of Bias Crime Arrest Patterns by Offender and Victim Race

Many hate crimes are not reported and even fewer hate crimes result in an arrest. This study investigates patterns of victim reporting and arrest for hate crimes in two parts. First, using data from the National Crime Victimization Survey, we find that, controlling for offense severity, hate crimes are less likely than non-bias crimes to be reported to the police and that the police are less likely to take further action for hate crimes, compared to non-hate crimes. Second, we use data from the Pennsylvania Human Relations Commission and the National Incident-Based Reporting System to compare differences between types of hate crimes in the likelihood of crime clearance. We find that those hate crimes most likely to result in arrest are those that fit the profile of a “stereotypical” hate crime: violent incidents, incidents committed by hate groups, and incidents involving white offenders and black victims.     

The effect of offenders' sex on reporting crimes to the police

This article examines the difference in victims' reporting behavior regarding crimes committed by males and by females. The authors expect that victims of female offenders are less likely to report to the police than victims of male offenders because of differences in the victim-offender relationship as well as in the victim's sex. With recent developments in Bayesian statistics, new tools have become available that enable the direct evaluation of researchers' expectations. All cases of robbery with assault from the National Crime Victimization Survey have been investigated (n = 478). Findings reveal that female offenders are underreported compared with male offenders and that this can be explained by the victim characteristics but only in combination with the offender's sex.     

A decade of child-initiated family violence: comparative analysis of child--parent violence and parricide examining offender, victim, and event characteristics in a national sample of reported incidents, 1995-2005

This article examines 11 years (1995-2005) of National Incident Based Reporting System data comparing victim, offender, and incident characteristics for two types of child-initiated family violence: child-parent violence (CPV) and parricide. The objective is to better understand the victim-offender relationship for CPV and parricide and to highlight distinguishing features between the two offenses. This work extends the research and addresses shortcomings in the extant literature. Data analysis consists of chi-square tests and logistic regression. Findings suggest that CPV and parricide are distinct and unique crimes. In short, parricide offenders and victims are both older than CPV offenders and victims, with CPV offenders more likely to be female, more likely to be African American, and less likely to use a weapon than parricide offenders. The study calls for future research and exploration of preliminary support for a family violence escalation hypothesis.     

The fear of reprisal and the failure of victims to report a personal crime

Most people who fail to report their victimizations to the police state either that the incident was not serious enough to warrant official attention or that nothing could be done. However, a small proportion of victims states that they did not report because of their fear of reprisal. Based on National Crime Panel victimization data, the offense and personal characteristics of these victims are contrasted with the total victim and nonreporting victim populations. Contrary to the general reasons for not reporting a crime, several personal and offense characteristics are related to reprisal. For instance, reprisal is more often a factor in personal victimizations where victims are female and acquainted with their offenders. The more dangerous the incident, the more often reprisal is the stated reason for not calling the police. The results of the analysis strongly suggest that in certain social environments the fear of reprisal is a major factor in the reporting of crime.     

Crime Reporting Decisions and the Costs of Crime

The paper develops a model of crime reporting based on an economic approach. It identifies the principal costs and benefits of reporting from the victim’s perspective, taking account of insurance provision and the risk of intimidation by an offender. It shows how a victim might use backward induction to infer a rational reporting strategy. The recording of crime by the police is a process that relies on victim reports, and is thus influenced by the reporting decisions made by victims. The paper uses empirical evidence from the British Crime Survey and from the International Crime Victims Survey to explore the hypotheses generated by the model. It finds support for the suggestion that the propensity to report a crime increases with the size of the loss entailed. The paper also explores the implications of the findings for the estimation of the costs of crime. Reporting and intimidation costs are generally excluded from bottom-up estimates of costs, an omission that may be quite serious in the context of offences such as domestic violence.     

Racial Bias in Case Processing: Does Victim Race Affect Police Clearance of Violent Crime Incidents?

Prior studies have illustrated racial differences in perceptions of police legitimacy. African‐Americans’ views, however, appear to be complex, shaped by perceptions of over‐enforcement of crimes committed by African‐American offenders coupled with under‐enforcement of crimes involving African‐American victims. Using data from the 2002 National Incident‐Based Reporting System, we examine whether victim race (alone, and in combination with offender race) affects police case clearance of four types of violent criminal incidents (homicide, aggravated assault, rape, and robbery) as a potential explanation of African‐Americans’ reduced levels of support for the police. Results suggest that the race of the victim, particularly in combination with the race of the offender, is related to police clearance of violent criminal incidents, but that this relationship is not as strong as those between agency, offense type, and situational characteristics of the incident. Implications for research and policy on police—community relations are discussed.     

Police Response to Crime

Abstract

Based on victim accounts provided by the National Crime Victimization Survey from 1992 to 1999, this paper examines issues related to police responses to reported incidents of assault, robbery, and rape. The primary goal was to determine the extent to which victim and offender race influence police responsiveness at various stages of the criminal justice system. The data indicate that overall, police exert more effort when victims are white. They arrive faster at the scene of the crime, and demonstrate more follow-up effort after the crime has taken place. However, they do not exert more, or less effort, during their initial visit to the crime scene, when there is proximate contact with the victims. This suggests that contextual factors may affect the penchant for discrimination. This relationship held even after controlling for other factors such as poverty, weapon use, injury to the victim, and location.     

Rape Co-occurrence: Do Additional Crimes Affect Victim Reporting and Police Clearance of Rape?

Despite the increased research attention given to rape and violence against women, little is known about rape co-occurrence, or rape incidents that involve another crime. Although previous research has found certain incident characteristics increase the likelihood that a victim reports her rape to police and that the offender is arrested and prosecuted, the relationship between co-occurrence and these responses is unknown. Given this gap in the literature, the main goal of the present research is to provide an initial understanding of rape co-occurrence and its effect on victim reporting and police clearance. To explore these issues, this study uses two national data sources that collect the requisite incident-level information: the National Crime Victimization Survey and the Uniform Crime Reporting Program’s National Incident-Based Reporting System. Few rapes are found to co-occur with other crimes. When rapes do occur with other crimes, though, they are more likely than solo-occurring rapes to involve weapons, strangers, additional injury to the victim, and multiple offenders. Rapes that co-occur also are more likely to be reported to police and cleared by police than rapes that occur with no other crimes.

Reversing the historical tide of iatrogenic harm: A therapeutic jurisprudence analysis of increases in arrests of domestic batterers and rapists

Therapeutic jurisprudence (TJ) proposes that the law is a social force that can heal or cause harm to parties in a legal action. Historically, women victims of intimate partner rape and domestic violence could not seek justice in the legal system because police, like other actors in the justice system, treated these offenses as private matters or fabrications. In domestic violence and intimate rape cases, TJ is concerned with the needs of the victims, and how the law and police play a role in increasing their well-being. In this article, we use a TJ approach to the study of police responsiveness to victims of these offenses by investigating arrests of the offenders pursuant to law reforms that encourage or mandate arrest. Given that in these offenses, victims have the lowest reporting rates of any violent crime, the victim decision to call the police represents an expectation that the mere physical presence of a police officer may redefine the nature of the violence from a private conflict to a societal wrong that will not be tolerated. Police partnership with and treatment of the victim with respect and dignity can change the dynamics of the violence, terminate the violence, and set the criminal justice process in motion by arresting the offender in most cases. Police arrest, and subsequent prosecution and conviction, sends a message to offenders that society does not tolerate their violence, and allows the victim to begin to heal. Yet, past research indicates that police are less likely to arrest intimates than acquaintances and strangers in misdemeanor and aggravated assault, rape, and sexual assault cases. Using the National Incidence Reporting System (NIBRS) for the year 2000, we examine police arrests of intimate partner rape and domestic violence in jurisdictions with mandatory and presumptive arrest policies compared to police arrests in full discretion jurisdictions. We also ascertain whether arrest rates are higher for strangers and acquaintances than for intimates in misdemeanor and aggravated assault, kidnapping, and rape and sexual assault. Third, we determine whether police arrests of intimate partner rape is more likely if there is evidence of violence, injury to the victim, and use of a weapon. Our multivariate findings suggest that both the rape and the domestic violence reform movements have reversed the tide of historical negative treatment of female victims of these offenses. Logistic regression analysis indicates that police agencies in mandatory and preferred arrest jurisdictions increase the odds of arrest for domestic violence incidents and violations of orders of protection, compared to police agencies in jurisdictions with permissive/discretionary arrest policies. In addition, intimate violence increases the odds of arrest by 98%; forcible rape accompanied by simple assault or kidnapping increases the odds of arrest by 467 and 222%, respectively whereas forcible fondling accompanied by simple assault increases the odds of arrest by 293%. We discuss the implications of our findings for future law reform as well as TJ.     

Effectiveness of the Restorative Justice Process on Crime Victims and Adult Offenders in Thailand

In this paper, the researchers draw on research findings of the restorative justice process for adult offenders in Thailand run by probation officers during the pre-investigation stage. The evaluation study was conducted in 2009, aiming to analyze the effect of restorative justice on victims and offenders. The researchers investigate various key aspects, such as rates of satisfaction and perception of fairness, changing attitudes of victims and offenders, response to the victim’s needs, offender’s accountability, and reoffending rate. Factors associated with these aspects were also analyzed. A quasi-experimental research design was applied and the research findings showed that victims and offenders participating in the restorative justice process were significantly more satisfied with almost all evaluated outcomes than those who did not. However, the study did not find any significant difference in the re-offending rate between offenders in the experimental and comparison groups. Finally, the study found that two factors, i.e. victim’s income and victim–offender relationship, significantly related to the victim’s satisfaction. Victims who had low income were more likely to be satisfied with the outcome than those who had high income and victims who previously knew the offender were more likely to be satisfied with the process than those who did not.     

Applying NIBRS Data to the Study of Intimate Partner Violence: Massachusetts as a Case Study

Using data from Massachusetts, we illustrate three ways in which National Incident-BasedReporting System (NIBRS) data can improve the collection of importantinformation on intimate partner violence. First, because NIBRS usesincident-based reporting, data are collected on all crimes associated witheach incident. In our sample of women victimized by an intimate partner, 10%had experienced more than one crime during the incident. Second, NIBRSinvolves expanded data collection on the offender–victim relationship, aswell as reporting about additional offenses. For female victims, partnerswere more likely than nonpartners to commit the crimes of simple assault,intimidation, and aggravated assault. For crimes involving male victims, anaquaintance was most likely to be the offender. Third, NIBRS data allow usto connect information about the incident, the offender(s), and thevictim(s). Our data indicted that several victim- offender-, and incident-relatedvariables were risk factors for injury, including victims ethnicity,offenders relationship to the victim, offender's use of a weapon, whether or not thecase was cleared, type of crime committed, and whether or not drugs and/or alcoholwere involved in the incident. Although there are several limitations to NIBRSdata, its potential usefulness to the study of intimate partner violence deserves furtherattention.     

Information,apprehension, and deterrence: Exploring the limits of police productivity

The capacity of police departments to solve crimes and apprehend offenders is low for many types of crime, particularly crimes of profit. This article reviews a variety of studies of police apprehension and hypothesizes that an important determinant of the ability of the police to apprehend criminals is information. The complete absence of information for many types of crime places fairly clear upper bounds on the ability of the police to effect solutions.To discover whether these boundaries are high or low we analyzed data from the 1973 National Crime Panel about the types and amount of information potentially available to police through victim reports and patrol activities. The evidence suggests that if the police rely on information made readily available to them, they will never do much better than they are doing now. On the other hand, there appears to be more information available to bystanders and passing patrols than currently is being used, which suggests that surveillance strategies and improved police methods for eliciting, recording, and analyzing information supplied by victims and witnesses might increase the probability of solving crimes and making arrests. In light of this we review a few possibly helpful innovations suggested in the literature on police productivity and procedure.
