* The CCSAO’s first contact with a felony case typically occurs through the Felony Review process. If an arresting agency decides to charge the arrestee with a felony,
the CCSAO’s Felony Review Unit (FRU) must be contacted to review the evidence and decide whether charges can be filed. Law enforcement can only directly file
felonies under limited circumstances, such as narcotics cases, non-felony traffic offenses, and misdemeanors. In some instances, a case may also be directly indicted
by a grand jury instead of going through the FRU process. Once the review process is complete, the FRU will either approve or decline to file the charges or choose to
continue the case for the police to further investigate. Approve: Sufficient facts and evidence support felony charges. Decline: the evidence presented is insufficient
to support felony charges. If felony charges are not approved by the CCSAO, police can refile the case as a misdemeanor. If initial charges are declined, the CCSAO can
call for the investigation to continue and will then review additional evidence when presented. The approval rate is calculated by dividing the number of approved
cases by the total number of reviewed cases. For example, the FRU reviewed 55 robbery cases - approved 50 and declined 5. The approval rate would be 50/ (50+5) =
91%. Sometimes the FRU will determine that there is not enough information yet from law enforcement to approve or decline charges, so they will classify the case as
a Continued Investigation (CI). CI’ed case numbers are not included here.

** Prosecuted: A case is moved through the system to a conclusion of guilty or not guilty; Guilty: defendant was determined to be guilty of criminal charges;
Conviction rate: Number of guilty dispositions (plea of guilty, finding of guilty, or verdict of guilty) divided by the number of cases prosecuted. Number of guilty
dispositions (plea of guilty, finding of guilty, or verdict of guilty) divided by the number of cases prosecuted. Cases that reached disposition during 1/1/2021-
10/31/2021 may have been initiated prior to this timeframe.

*** Diversion can occur at many points throughout the criminal justice process. As the prosecuting body for Cook County, diversion for the CCSAO refers to
connecting defendants to services and programs (e.g., assistance with substance abuse, employment, mental health treatment, etc.), rather than sentencing them to
time in custody. Assistant State’s Attorneys screen cases and refer eligible defendants to diversion programs. There are pre-plea and post-plea court-based diversion
programs available in Cook County; five are pre-plea diversion programs overseen by the CCSAO, and three are post-plea programs overseen by the Office of the
Chief Judge. Learn more about Cook County diversion programs. Referral is the number of individuals referred to a diversion program. Graduated is the number of
individuals who successfully completed a diversion program. Failed is the number of people who either dropped out of a diversion program or were disqualified from
the program (for example getting rearrested). The graduation rate is defined as the number of graduates divided by the number of individuals who either graduated
or failed a program.

**** Arrest Rate: Number of criminal incidents that resulted in at least one offender being arrested divided by the total number of reported criminal incidents.

***** Reported Incidents are categorized by the CPD using Illinois Uniform Crime Reporting (IUCR) Codes. Exception: An incident is categorized as Shooting when the
incident report mentioned people being shot. Shooting incidents commonly include homicide, reckless discharge of firearm, etc.

****** Theft includes, but is not limited to: Under $500, Retail Theft, Pocket-Picking, and Purse Snatching.
