Chicago Tribune News Applications

Our audience

Highly flexible data == need for a clear audience definition

  • Locals who want a picture of crime in their neighborhood.

  • Community leaders & stakeholders
  • Academics, students, niche media
  • Policy-makers & political figures

"How bad is it?"

Reported crime incidents aren't a total picture of crime.

Some crimes are historically underreported.

Our goals

  • Extend the Tribune's crime reporting to data.
  • Provide context to data so that numbers become stories.
  • Show trends over 13 (and counting) years of data.
  • Help readers find information about incidents near them which might not get a full reporting treatment.
