Police incidents since 1988. Dates before that are incomplete - and could be data entry errors. | MAPPING NOTE! Some addresses will not appear on maps because streets no longer exist or are not recognized by the mapping databases.
City staff inspect rental properties on a rotating basis, assigning a letter grade ("Class A", "Class B", etc.).
This dataset shows only the most recent grade for a property. The "Rental Inspection Grades History" dataset shows all historical inspections (that are electronically available), including multiple ones at each location.
Police incidents since 1988. Dates before that are incomplete - and could be data entry errors. | MAPPING NOTE! Some addresses cannot be mapped properly. Addresses that cannot be mapped will cluster on Vine, just north of University. Address mapping fails because streets no longer exist or are not recognized by the mapping tool.
The information is the same data transmitted to the Illinois Department of Transportation (IDOT) with two additions: the "Motivation for Stop", and the offense codes recorded.
IMPORTANT!! (please click "More" to read this...) Adding the Offense Codes means that each line of information represents a single Offense.
For example: a traffic stop for speeding results in an arrest for an outstanding warrant and for possession of narcotics. That would appear on this listing THREE times (speeding, arrest warrant, and narcotics). The Incident Number will be the same (and the driver demographics), but the Crime Codes will be different on each line.
So counting rows of this dataset will return a higher count than the actual stops. This will cause some discrepancies with State data, which only count each stop once.
