Tempe Police Calls for Service Under NIBRS Reporting, 2022-Present

From 2022 to present, the Tempe Police Department records all calls for service, including dispatched responses and officer-initiated incidents, reported under the FBI's National Incident-Based Reporting System (NIBRS). This consolidated dataset is published by the City of Tempe and was last updated in March 2026. The data provides detailed incident information, replacing the older Uniform Crime Report (UCR) summary system.

Use Cases

• Analyzing spatial and temporal patterns of police service requests based on the geospatial and temporal incident data.
• Modeling demand for police resources based on call types and frequencies mentioned in the description.
• Comparing incident details and circumstances before and after the 2022 transition to the NIBRS reporting system.
• Studying the relationship between dispatched calls and self-initiated officer activity described in the dataset.

Strengths

• Data follows the detailed FBI NIBRS standard, which captures multiple offenses, victims, offenders, and property per incident.
• Published under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.
• Available in multiple formats including CSV, GeoJSON, and ArcGIS REST API for flexibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Trends and numbers should not be directly compared with pre-2022 UCR data, as noted in the description.
