Cook County Elections Data at Chicago City Data User Group

The theme of this month’s Chicago City Data User Group was election data. Ryan Chew, the Deputy Director of Elections from the Cook County Clerk’s office, and Geetha Lingham, manager for voter and ballot data, presented on the process and data used to run elections for Suburban and Unincorporated Cook County.

Also in attendance were students from the Latin School of Chicago’s Social Justice class.

Ryan spoke about the process involved to maintain accurate voter registration data.

Geetha focused on the process used to verify addresses to assign the proper boundaries and ballot styles for each voter.
