This paper explores the main challenges in measuring violent crime. Most violent crime data originate from civilian calls for service that result in a police report. We review research on the factors influencing whether victims contact the police and on police report-writing practices. We examine how these factors affect research that estimates the causal impact of policies and interventions on violent crime, highlighting how shifts in victim and police reporting can introduce bias in these estimates. Finally, we assess the strengths and limitations of various data sources for measuring violent crime and provide some key lessons for future research.
