Official Crime Statistics: Their use and Interpretation

Abstract

In this paper we consider the data used by economists to estimate economic models of crime. We discuss the main sources of Official Crime Statistics in the United Kingdom, Europe and the United States, and raise questions about the reliability of these data for estimation and forecasting purposes. In particular, we focus on the disparity between crime rates suggested by victimisation surveys and the rates suggested by Official Statistics, and show that this is primarily a consequence of under-reporting by victims and under-recording by the police. We conclude our analysis by considering the factors that influence the under-reporting of crime.
