The Crime Data Handbook

Crime research has grown substantially over the past decade, with a rise in evidence-informed approaches to criminal justice, statistics-driven decision-making and predictive analytics. The fuel that has driven this growth is data – and one of its most pressing challenges is the lack of research on the use and interpretation of data sources. This accessible, engaging book closes that gap for researchers, practitioners and students. International researchers and crime analysts discuss the strengths, perils and opportunities of the data sources and tools now available and their best use in informing sound public policy and criminal justice practice.

Quantitative criminology has certainly come a long way since I was ?rst introduced to a largely qualitative criminology some 40 years ago, when I was recruited to lead a task force on science and technology for the President’s Commission on Law Enforcement and Administration of Justice. At that time, criminology was a very limited activity, depending almost exclusively on the Uniform Crime Reports (UCR) initiated by the FBI in 1929 for measurement of crime based on victim reports to the police and on police arrests. A ty- cal mode of analysis was simple bivariate correlation. Marvin Wolfgang and colleagues were makingan importantadvancebytrackinglongitudinaldata onarrestsin Philadelphia,an in- vation that was widely appreciated. And the ?eld was very small: I remember attending my ?rst meeting of the American Society of Criminology in about 1968 in an anteroom at New York University; there were about 25–30 people in attendance, mostly sociologists with a few lawyers thrown in. That Society today has over 3,000 members, mostly now drawn from criminology which has established its own clear identity, but augmented by a wide variety of disciplines that include statisticians, economists, demographers, and even a few engineers. This Handbook provides a remarkable testimony to the growth of that ?eld. Following the maxim that “if you can’t measure it, you can’t understand it,” we have seen the early dissatisfaction with the UCR replaced by a wide variety of new approaches to measuring crime victimization and offending.

A comprehensive core text with chapters written by twenty-three key researchers. Collaborating with these prominent researchers in each of the topics covered, Sheley provides readers with a current and comprehensive overview of the discipline. The authors provide timely, critical analyses of their areas of expertise, giving readers state-of-the-art coverage of standard criminology topics as well as information on topics often missing in other texts. The chapters also address many crime myths, enabling students to make informed decisions about crime and its potential effect on them.

In recent years, the fields of crime analysis and environmental criminology have grown in prominence for their advancements made in understanding crime. This book offers a theoretical and methodological introduction to crime analysis, covering the main techniques used in the analysis of crime and the foundation of crime mapping. Coverage includes discussions of: The development of crime analysis and the profession of the crime analyst, The theoretical roots of crime analysis in environmental criminology, Pertinent statistical methods for crime analysis, Spatio-temporal applications of crime analysis, Crime mapping and the intersection of crime analysis and police work, Future directions for crime analysis. Packed with case studies and including examples of specific problems faced by crime analysts, this book offers the perfect introduction to the analysis and investigation of crime. It is essential reading for students taking courses on crime analysis, crime mapping, crime prevention, and environmental criminology. A companion website offers further resources for students, including flashcards and video and website links. For instructors, it includes chapter-by-chapter PowerPoint slides.

Successfully analyze crime at any level of law enforcement! This book is a practical resource guide for the development of crime analysis in local law enforcement. The tragedy of September 11, 2001, has raised awareness on how crucial it is to analyze information and intelligence. Smaller agencies that cannot financially justify hiring a full-time analyst will find strategies and techniques to teach officers the methods of analysis. Introduction to Crime Analysis: Basic Resources for Criminal Justice Practice provides basic tools and step-by-step directions that will improve the skills and knowledge of new crime analysts. From the editors: “Military strategists have used analysis for centuries; it makes sense to know as much as possible about the enemy and about the conditions and causes of a situation if we hope to institute any kind of significant change for the better. Career criminals are the enemies of a community's well being. Now that advances in information technology give us the means and methods to fully examine and find meaningful knowledge in the vast amounts of existing information on crimes and criminals, we have an obligation to use our technological strength to protect innocent people. Systematic crime analysis as a law enforcement and public safety asset has become not only possible, but also truly necessary as a weapon in the war against crime.” Along with defining the various roles of the crime analyst, Introduction to Crime Analysis demonstrates how to: improve the personal skills necessary to make you a good crime analyst successfully work through the five stages—collection, collation, analysis, dissemination, and feedback and evaluation—of analysis select the appropriate crime mapping software for your agency evaluate the usefulness of your crime analysis products benefit from email discussion groups and professional associations create a crime analysis unit-including policies and procedures as well as marketing and funding This clearly written resource includes case studies, figures, and appendixes that will simplify the learning process. Links to Internet pages also offer resources and information beneficial to both new and experienced crime analysts. Introduction to Crime Analysis will benefit crime analysts, police officers, intelligence analysts, community groups focused on crime prevention, criminal justice students, and police departments and sheriff’s agencies.

Crime statistics are everywhere, but how do you know when they’re valid? If a newspaper report says "the rate of overall violent crime decreased by 0.9 percent," how can you tell where that statistic came from, what it measures, and how accurate it is? Is it worth repeating or sharing? Measuring Crime: Behind the Statistics gives you the tools to interpret and evaluate crime statistics’ quality and usefulness. The book focuses on ways of thinking about crime statistics (no formulas!) and features Eight questions you should ask before quoting a statistic The two sources of information about homicide FBI statistics: what do they measure? How victimization surveys can reflect your experiences even though you were not asked to participate Special considerations when interpreting statistics about sexual assault and fraud Examples of experiments and studies on how to improve crime statistics Two online supplements containing additional details and links to data sources Whether you are a law enforcement professional, journalist, student, or interested citizen, Measuring Crime: Behind the Statistics will tell you how to read statistics as a statistician would. Sharon Lohr, the author of Sampling: Design and Analysis, has published widely about statistical methods for education, public policy, law, and crime. She has been recognized as Fellow of the American Statistical Association, elected member of the International Statistical Institute, and recipient of the Gertrude M. Cox Statistics Award and the Deming Lecturer Award. Formerly Dean’s Distinguished Professor of Statistics at Arizona State University and a Vice President at Westat, she is now a freelance statistical consultant and writer.

These are disparate topics, but in the way they are approached here, there is a strong synergy that reinforces both aspects. One the one hand, the reader's natural curiosity about crime (what is it, how are crime events classified and reported, how reliable are the numbers you see in the newspaper, etc.) will help him/her become interested in the statistical issues and learn these concepts in a practical and concrete setting. And on the other hand, by reading about the statistical issues surrounding crime data, he/she gains a better appreciation for the complexities of crime statistics, eventually acquiring a deeper understanding of them. As a statistician myself, I learned interesting facts about the types of crime, their nomenclature and the possible confusion surrounding them, and how the data are collected and reported. Overall, I think the combination is effective and very well developed in this book." (Jean Opsomer, Westat) "This book is an excellent primer on handling the mass of data and information researchers are faced with. While it is geared toward followers of criminal justice information, much of the book is a very good introduction to survey techniques discussing their strong and weak points. Most importantly, there are very good guidelines and questions that one should employ before citing any data or using data for policy decisions or for reporting on data such as journalists do. The book is written in a non-technical manner and does a very good job of explaining the nuances in reviewing data. Any researcher who utilizes data would find this valuable. While it has specific examples in the criminal justice field, it really is quite useful for any user of data." (Barry Nussbaum, former President American Statistical Association)
