Where the Cases Are
22,729 incident locations plotted (1-in-10 sample of the full year) — the point cloud alone traces Chicago's shape.
Violent crime 72,109

Violent crimes (homicide, robbery, assault, battery, criminal sexual assault, kidnapping, weapons violations) are weighted 3× against property and other offenses when computing each neighborhood's Safety Score.

Neighborhood Scores at a Glance
Safety Score (0–100, higher = safer): weighted crimes per 1,000 residents, normalized so the highest-crime-rate area = 0 and the lowest = 100.

How These Scores Are Calculated
Safety Score (0–100): Violent crimes are weighted 3×, property/other crimes 1×. We sum weighted crimes per community area, divide by population, and scale to a rate per 1,000 residents. Rates are then normalized across all 77 areas — the highest rate becomes 0, the lowest becomes 100.
Intelligence Score (0–100): 50% Safety Score + 50% walkability/amenities.
Walkability is currently a placeholder value pending integration of a real Walk Score (or equivalent) dataset — treat Intelligence Score as directional only until that lands.
