Requesting Raw Data

[elizluh]

Hi ProPublica Staff,

Thank you for posting the ticket data on your website. I am a doctoral candidate in Economics at the University of Houston. I'm currently writing a paper using the fine increase as a way to identify Chicago police's disparate policing behavior across black and non-black neighborhoods. Using the available data, my preliminary results show that police are 5-10% more likely to give the sticker fine to black neighborhoods compared to non-black neighborhoods after the fine increased.

I'd like to analyze each instance the city gave a ticket holder a notice, but the available data only has the most recent notices. Would your team be willing to let me have a look at the raw data? I'd like to test which channel of enforcement (seizure or drivers' license suspension) had a higher impact on the disproportionate increase in bankruptcy rates in black neighborhoods after the 2012 increase. I'd like to be able to identify the number of notices each person got from their parking ticket to better identify the channel of disparate policing.

Thank you very much for your time!

Sincerely,
Elizabeth
