Biking while black

The vast majority of Chicago bike tickets go to cyclists in black neighborhoods, despite past criticism by community and cycling advocates that enforcement is uneven across the city.

For this story I performed the data analysis that drove the story, written by Mary Wisniewski of the Chicago Tribune. I plotted and analyzed tens of thousands of bike citations to show where these citations — mostly for riding a bicycle on the sidewalk — were being issued. An initial report (archive link) came out in the spring of 2017. A follow up early in 2018 (archive) showed — despite promises from city official that change would happen — the pattern continued. For publication I created multiple maps and charts to display online and in print.
