Can machine learning and statistical methods determine the risk of hate crime for demographics in New York City? How can data science inform local policy and action on combating hate crimes? Modelling hate crime occurrences yields less-than-promising levels of accuracy, but there is a clear and significant connection between certain demographics and the bias challenges they face. This analysis is conducted through a series of predictive models such as neural networks and support vector machines, chi square tests, loglinear models, and dependence modeling, and uses packages including tidyverse, ggplot2, caret, MASS, lubridate, sf, maditr, and tigris. The NYC data contains 1,810 hate crime reports (2018-2022) distinguished by county, a specific and broader bias category, and a binary misdemeanor/felony variable. The primary hate crime data is supplemented by demographical data of the counties within NYC, collected from 2015 Census data. This includes population data, percentages of different demographics, income and poverty levels, and more.-- Abstract.

Using data from the Uniform Crime Reporting Hate Crime Statistics Program and the National Crime Victimization Survey, this brief highlights the uniqueness of hate or bias crime victimization. It compares these to non-bias crimes and delineates the situational circumstances that distinguish bias from non-bias offending. The nuances of under-reporting shed light on bias-group and victim reasons for not reporting. By examining measurement issues associated with data collection systems, this brief helps explain why eighty-nine percent of participating law enforcement agencies report zero hate crimes each year. It describes patterns and trends in reporting the volume of general bias motivations and specific bias types, as the most prevalent hate crime offense types and most likely victims and offenders. With recommendations to address issues in measurement and under-reporting, including an action plan by the Enhance the Response to Hate Crimes Advisory Committee and the International Association of Chiefs of Police, a best practice model by the Oak Creek Police Department, and other promising law enforcement reporting models, this brief provides an increasingly critical resource for law enforcement practitioners and researchers dealing with hate crimes.

This manual is intended to assist law enforcement agencies in reporting incidents of hate crime to the FBI Uniform Crime Reporting (UCR) Program. It addresses policy, the types of bias crime to be reported, how to identify a hate crime and guidelines for reporting hate crime. Since 1991, thousands of city, college and university, county, state, tribal, and federal law enforcement agencies have voluntarily participated in the hate crime data collection. It is the law enforcement officers within these agencies who investigate offenses, determine those motivated by bias, and report them as known hate crimes that have made crucial contributions to the success of the hate crime data collection. Without their continued support and participation in identifying bias-motivated crimes, the FBI would be unable to annually publish Hate Crime Statistics. This partnership and, ultimately, this publication serve as the cornerstone in raising the nation's awareness about the occurrence of bias-motivated offenses.

To derive statistics about crime â€" to estimate its levels and trends, assess its costs to and impacts on society, and inform law enforcement approaches to prevent it â€" a conceptual framework for defining and thinking about crime is virtually a prerequisite. Developing and maintaining such a framework is no easy task, because the mechanics of crime are ever evolving and shifting: tied to shifts and development in technology, society, and legislation. Interest in understanding crime surged in the 1920s, which proved to be a pivotal decade for the collection of nationwide crime statistics. Now established as a permanent agency, the Census Bureau commissioned the drafting of a manual for preparing crime statisticsâ€"intended for use by the police, corrections departments, and courts alike. The new manual sought to solve a perennial problem by suggesting a standard taxonomy of crime. Shortly after the Census Bureau issued its manual, the International Association of Chiefs of Police in convention adopted a resolution to create a Committee on Uniform Crime Records â€"to begin the process of describing what a national system of data on crimes known to the police might look like. The key distinction between the rigorous classification proposed in this report and the "classifications" that have come before in U.S. crime statistics is that it is intended to partition the entirety of behaviors that could be considered criminal offenses into mutually exclusive categories. Modernizing Crime Statistics: Report 1: Defining and Classifying Crime assesses and makes recommendations for the development of a modern set of crime measures in the United States and the best means for obtaining them. This first report develops a new classification of crime by weighing various perspectives on how crime should be defined and organized with the needs and demands of the full array of crime data users and stakeholders.

This work provides clear application of a new statistical modeling technique that can be used to recognize patterns in victimization and prevent repeat victimization. The history of crime prevention techniques range from offender-based, to environment/situation-based, to victim-based. The authors of this work have found more accurate ways to predict and prevent victimization using a statistical modeling, based around crime concentration and sub-group profiling with regard to crime vulnerability levels, to predict areas and individuals vulnerable to crime. Following from this prediction, they propose policing strategies to improve crime prevention based on these predictions. With a combination of immediate actions and longer-term research recommendations, this work will be of interest to researchers and policy makers in focused on crime prevention, police studies, victimology and statistical applications.

Significant variation among the legal and scholarly definitions of hate crimes impact how these crimes are measured. Although scholars tend to use the Uniform Crime Reports to understand the scope of hate crime in the United States, these data suffer from limitations due to this lack of conformity as well as the future of local agencies to submit hate crime statistics. Furthermore, a crime has to be reported to police to be counted in the UCR data. Using the National Crime Victimization Survey (NCVS) 1992-2005, this paper examines the factors related to police reporting behavior by violent hate crime through analyzing the demographic (gender, race, education, age, urban location) and the contextual characteristics of the incident (victim-offender relationship, severity: injury to victim, weapon used, multiple offenders). Particular attention was given to racial hate crimes to investigate differences within hate crime victimization categories. Understanding the mechanisms of police reporting behavior is important because the failure of victims to contact authorities undermines the ability of the criminal justice system to appropriately punish hate crime offenders and effectively deter future incidents. Supporting previous studies on victimization reporting, severity of the incident, gender and offenders unknown to the victim significantly and substantially increased reporting likelihood. Most interestingly, race did not dramatically impact reporting behavior for total hate crime, but had a significant and substantial effect on racial hate crime. Victimizations of Whites were more than 50 percent more likely to be reported than Non-White victimizations for racial hate crime.

The fledgling field of hate crime has turned out mostly descriptive research since the Hate Crime Statistics Act was enacted in 1990. Hate crime causation, an exceedingly important area of inquiry, has been severely neglected. In a novel approach, literature on the causes of historical lynchings and contemporary intergroup conflict was reviewed in addition to hate crime research. This dissertation also applied Robert Agnew's macro-level version of his general strain theory (MST) to empirically examine hate crime causality. The basic premise of MST is that an increase in community crime rates is a common consequence of the strain produced by those communities. The primary dependent variable of the study was the rate of hate crime with the other dependent variables representing the offense types and bias motivations of hate crime. The types of offenses chosen for analysis were crimes against persons and crimes against property.^Anti-racial, anti-religion, anti-ethnicity/national origin, anti-sexual orientation, and anti-disability comprised the general bias motivations while the categories of specific bias motivations included anti-white, anti-black, and anti-Hispanic. The independent variables were used as measures of MST and were meant to embody the categories of economic deprivation, social cleavages, and family disruption. Economic deprivation was operationalized using variables consisting of poverty, unemployment, and educational attainment. Indicators of social cleavages included variables associated with heterogeneity, density/overcrowding, and population mobility. Family disruption measures related to divorce or separation and single parent families. Control variables were also incorporated because they have been found to have significant effects on crime. These control variables corresponded to race, region, age, and gender.^Data for the hate crime measures came from the Uniform Crime Report while the indicators of strain and control variables were created from Census data. The two data sets for the year 2000 were linked using FIPS county codes, which established a unique, never-before-used data set. Informed by the literature reviewed and the theoretical framework employed, hypotheses were generated and analyses were performed. Results for the correlation and unstandardized coefficients for the bivariate and multivariate analyses, respectively, yielded mixed results and only partial support for Agnew's macro-level general strain theory.
