Violent crime in America shot up sharply in the mid-1980s and continued to climb until 1991, after which something unprecedented occurred. The crime level declined to a level not seen since the 1960s. This revised edition of The Crime Drop in America focuses first on the dramatic drop in crime rates in America in the 1990s, and then, in a new epilogue, on the patterns since 2000. The separate chapters written by distinguished experts cover the many factors affecting crime rates: policing, incarceration, drug markets, gun control, economics, and demographics. The detailed analyses emphasize the mutual effects of changes in crack markets, a major focus of youth violence, and the drop in rates of violence following decline in demand for crack. The contrasts between the crime-drop period of the 1990s and the period since 2000 are explored in the new epilogue, which also reviews major new developments in thinking about the causes and control of crime.

This book examines several contentious and under-studied criminal career issues using one of the world's most important longitudinal studies, the Cambridge Study in Delinquent Development (CSDD), a longitudinal study of 411 South London boys followed in criminal records to age 40. The analysis reported in the book explores issues related to prevalence, offending frequency, specialization, onset sequences, co-offending, chronicity, career length, and trajectory estimation. The results of the study are considered in the context of developmental/life-course theories, and the authors outline an agenda for criminal career research generally, and within the context of the CSDD specifically.

The National Institute of Justice (NIJ) is the research, development and evaluation agency of the US Department of Justice. The NIJ is dedicated to improving knowledge and understanding of crime and justice issues through science. NIJ provides objective and independent knowledge and tools to reduce crime and promote justice, particularly at the state and local levels. Each year, the NIJ publishes and sponsors dozens of research and study documents detailing results, analyses and statistics that help to further the organization's mission. These documents relate to topics like biometrics, corrections technology, gun violence, digital forensics, human trafficking, electronic crime, terrorism, tribal justice and more. This document is one of these publications.

Volume II takes an in-depth look at the various aspects of criminal careers, including the relationship of alcohol and drug abuse to criminal careers, co-offending influences on criminal careers, issues in the measurement of criminal careers, accuracy of prediction models, and ethical issues in the use of criminal career information in making decisions about offenders.

By focusing attention on individuals rather than on aggregates, this book takes a novel approach to studying criminal behavior. It develops a framework for collecting information about individual criminal careers and their parameters, reviews existing knowledge about criminal career dimensions, presents models of offending patterns, and describes how criminal career information can be used to develop and refine criminal justice policies. In addition, an agenda for future research on criminal careers is presented.
