The Justice Information Resource Network (JIRN), through funding from the Bureau of Justice Statistics (BJS), facilitates information sharing and collaboration among the Statistical Analysis Centers (SACs). In addition, the online community will also serve as a resource for JRSA, BJS, criminal justice researchers, policy makers, and other stakeholder to keep up to date with SAC research publications.

Item An analysis of variables affecting the clearance of homicides: A multistate study(Justice Research and Statistics Association, 1999-10) Wellford, Charles; Cronin, JamesIn recent years, the ability of law enforcement to make arrests in crimes would appear to have significantly diminished. This is especially true for homicide: from 1980 to 1996, the clearance rate for homicides decreased more than 7 %. While there has been a decrease in clearance rates nationally, some cities have high clearance rates for total crime and for homicides, and others have much lower rates than the average. Analysis of clearance rates from 1980 through 1994 shows that clearance rates in cities have remained very stable: those cities that are high in total clearance and high in homicide rates have remained consistently so throughout this period, as have cities which are high-low, low-high, and low-low. This stability suggests the existence of persistent factors that affect law enforcement agencies’ ability to clear homicide cases. The purpose of this study was to identify these factors by comparing the characteristics of solved and unsolved homicide cases. This study examined 798 homicides that occurred in four large U.S. cities during 1994 and 1995. These cities were selected to maximize variation on homicide and total index crime clearance rates measured from 1980 through 1993. The cities include one that had relatively low homicide and total index crime clearance rates; another that had high homicide clearance rates and low total clearance rates; a third that had a high total clearance rate, but low homicide; and a fourth that had high total clearance and high homicide crime clearance.Item Domestic Violence and Sexual Assault Data Collection Systems in the States(Justice Research and Statistics Association, 1999-10) Orchowsky, StanThe Violence Against Women Act of 1994 specified that a study be conducted of “how the States may collect centralized data bases on the incidence of sexual and domestic violence offenses within a State.” The National Institute of Justice (NIJ) asked the Justice Research and Statistics Association (JRSA) to undertake a study of domestic and sexual violence incident data collection by the states. The study involved convening a panel of experts and surveying state Statistical Analysis Center (SAC) directors to determine how these data were collected in their states. The findings of this study were published in July 1996 in an NIJ Research Report entitled Domestic and Sexual Violence Data Collection. In 1997, JRSA began the second phase of the study, which was designed to expand upon the findings of the first effort. The first step in this second study was to update the survey of SAC directors which provided the information included in the 1996 report. Changes in data collection procedures were noted, and the SAC directors were asked to provide the names of contacts in their states who could provide additional information on the states’ databases. JRSA then interviewed these contacts, along with the directors of the state domestic violence and sexual assault coalitions, to obtain detailed information on the data collection systems. Copies of data collection forms and other system documentation were also obtained. The study also examined the data collection systems in three states in greater detail by having the SACs in those states study and report on their state systems. The three state “case studies” were conducted in: (1) Iowa, which studied its National Incident-Based Reporting System (NIBRS)-compatible incident based crime reporting system; (2) Connecticut, which examined its Family Violence Reporting Program, a specialized domestic violence data collection system; and (3) Illinois, which studied its new automated system for collecting domestic violence and sexual assault service provider data. Each SAC conducted interviews with knowledgeable individuals who provided information about how the data systems functioned, and surveyed data providers to determine how the information was collected and used at the local level.Item Identifying domestic violence in North Carolina(Criminal Justice Analysis Center., 2023-02) Governor's Crime Commission NC Department of Public SafetyDomestic and family violence must be clearly defined before analyzing the prevalence of domestic violence in North Carolina using the National Incident-Based Reporting System data. NIBRS provides our current framework for measuring the prevalence of domestic violence. Its instructions allow assignment of a domestic violence circumstance code only to reports that involve aggravated assault or homicide. NIBRS also provides a definition of domestic violence that includes the use of force, or a Crime Against Property when the offender is in a current or former relationship with or a family member of the victim. Further analysis of the frequency of crimes committed by persons known to the victim was conducted to get a clearer picture of domestic and family violence incidents across the state. In this paper, the North Carolina Governor’s Crime Commission – Criminal Justice Analysis Center presents analysis of NIBRS crime data that classifies all Crimes Against Persons committed by a current or former intimate partner or family member as domestic and family violence. This definition broadens the review of domestic violence cases to include reports of simple assault, kidnapping, intimidation and other crimes.
