Name: Traffic Accidents
Display Field: GEOID20
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This feature class represents census tracts, enriched with data on traffic accidents and population demographics. Each polygon corresponds to a census tract and contains the total number of traffic accidents [TRAFFIC_ACCIDENT_COUNT], total population from the 2021 ACS 5-year estimates [POPULATION_TOTAL], and a calculated traffic accident rate per 1000 people [TRAFFIC_ACCIDENT_RATE]. The traffic accident rate is calculated using the provided expression, "(TRAFFIC_ACCIDENT_COUNT/(TOTAL_POPULATION/1000))", which offers a per capita perspective of traffic accidents. The dataset is generated in FME, where traffic accident count data from an internal database is spatially intersected and summarized within the 2020 Census Tracts polygons, ensuring a comprehensive and geographically accurate representation of traffic accident occurrence in relation to population density.
