The dataset also includes the year of the event, the race/ethnicity of the individual, the county where it occurred, the geographic region of that county, and the rural/urban designation for that county. Arrest information is protected per our data sharing agreement with the Illinois State Police. Specific modifications have been made to arrest data.
