This map tracks crime and city service trends over time, for any Chicago location and level of detail you choose.
The timelines trace each indicator back several years, so a recent spike or drop can be read against the longer pattern behind it. Watching several at once shows which tend to rise and fall together, which stay steady, and which reflect rare one-time events.
The timelines also make it easy to spot which indicators move together, which hold steady, and which reflect rare events. Seeing what's actually shifting over time is how the city can tell whether its public safety efforts are working.
