The Custom Report tool is a powerful search tool which provides flexible query options for Incident-Based (NIBRS) reported crime. The tool offers a multitude of search criteria which can allow the user to tailor their request to specific criteria. It also allows the user to display the data in a variety of charting formats. 

The Anomaly Reports go a step beyond the FBI’s validation rules and display incidents that may need additional attention to verify that the incident correctly reflects the details of the crime. These incidents may be correct as they are, but contain an unusual combination of data elements which may generate an FBI request for incident verification or correction.

The Distribution Breakdown report is similar to the Offense Distribution Report and Arrest Distribution Report as it displays two demographic characteristics instead of one. The report can drill down into any one characteristic and display the breakdown of a second characteristic.

The Year-to-Date Comparison Report show the number of offenses, clearances, stolen and recovered property for the current year-to-date compared with the same period in the previous year in various reports. This allows an agency to determine if there is a marked increase or decrease in crime or if there was an issue in reporting crime.

The Offense Density Report shows the geographic distribution of Offense by county. This report shows hotspot areas that may need extra resources.

The Offense Trend Reports show the number of offenses on a monthly basis for the selected time period. This analysis is useful to help forecast the volume of crime or analyze crime patterns.
