A statistical modeling student has mapped Chiacgo drug possession charges by type and then overlaid them on a map of CTA elevated lines. The results are fascinating, to say the least.
Lauren Baily tweeted the map last week. She even noted the drugs by color. Light blue = cocaine; black= heroin; purple = crack; pink= pills. I’m not sure where pot charges fit in. In a separate tweet, she noted that light blue (cocaine) seemed to cluster around the Blue Line.
Nice work, Lauren.
