“If they’re not going to solve the problem . . . . then we’re going to solve the problem for them. Because we’re going to have to do something,” Trump said of Chicago officials. “What’s happening in Chicago should not be happening in this country.”

Research goal We want to estimate criminal vilolence level in Chicago using open data that is too really big for primitive handy calculations.

Data We use dataset “Crimes - 2001 to present” from data.gov. This dataset reflects reported incidents of crime that occurred in the City of Chicago from 2001 to present. Data is extracted from the Chicago Police Department’s CLEAR (Citizen Law Enforcement Analysis and Reporting) system. For more about Chicago criminal data see https://catalog.data.gov/dataset/crimes-2001-to-present-398a4.
