Description: This dataset consists of individual arson incident locations reported in Chicago during the 2020 calendar year. Each point represents a geocoded event classified as an arson offense in the City of Chicago crime database. The dataset is used for spatial aggregation into community boundaries and provides the source counts for calculating arson rates per 1,000 residents.These incident points form the fundamental input for spatial statistics, including Getis–Ord Gi* hotspot analysis and Local Moran’s I cluster/outlier analysis. They also support visualization of event density and spatial patterns of fire-related criminal activity. Attributes typically include crime date, location, and offense classification.Temporal Scope: January 1 – December 31, 2020.
