Defining Murder in Official Statistics
How Chicago Police Classify Criminal Homicides
Chicago police and the Cook County Medical Examiner’s Office categorize murders based on intent, mechanism, and investigation status. The data below focus on criminal homicides as coded in the department’s annual reports.
Each incident is counted once the preliminary investigation meets criteria for justifiable homicide, self-defense exceptions, or a determination that a crime occurred. Understanding this definition is essential for interpreting yearly fluctuations and long-term trends.
