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.

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 rows of city data to show where these citations — mostly for riding a bicycle on the sidewalk — were being issued. An initial story was published in the spring of 2017. A follow up early in 2018 (archive) showed — despite promises from city officials that change would happen — that the pattern continued.

I created multiple maps and charts to display online and in print.

Here is a link to the graphics for the piece. The Chicago Tribune website recently switched over to a new CMS, which broke many of my interactive pieces. I am in the process of fixing them, so in the meantime I am including links to off-site versions.
