Specifically, the contributors explore the issues surrounding divergence in the Uniform Crime Reports (UCR) and the National Crime Victimization Survey (NCVS), which have been the two major indicators of the level and of the change in level of crime in the United States for the past 30 years. This book examines recent changes in the UCR and the NCVS and assesses the effect these have had on divergence. By focusing on divergence, the authors encourage readers to think about how these data systems filter the reality of crime. Understanding Crime Statistics builds on this discussion of divergence to explain how the two data systems can be used as they were intended - in complementary rather than competitive ways.
