Police decisions to record or not record incidents as crimes are an important but neglected aspect of discretionary decisionmaking in the criminal justice system. Findings of this study show that the poverty of the neighborhood increases nonrecording of burglaries, while increases in the percentage of foreign-born and in the mobility rate decrease nonrecording. Demand for service also increases nonrecording, but only when neighborhoods with extremely high demand are included. There is considerably less evidence for effects of neighborhood characteristics on the recording of assaults. The literature shows that police are more likely to make arrests in poor neighborhoods. That point must be viewed as consequential to the findings of this study that police are less likely to record crime in poor neighborhoods. Only when these behaviors are viewed in combination will a clearer picture emerge of police discretionary behavior and its implications for measurement error in macro-level studies. In turn, these findings must be understood in the broader context of different urban political structures. The findings have important implications for understanding both police decisionmaking and potential biases in the distribution of official counts of recorded crime. Notes, tables, references, appendix
