Block, Carolyn Rebecca HOHICIDES IN CHICAGO, 1965-1981 (ICPSR 8941) S~~RY: This dataset contains information on every homicide in Chicago Police Department murder analysis files for the years 1965-1981. Data are provided on place of homicide, sex, race, and age of victim, time of occurrence, type of weapon used, age, race, and sex of offender, and relationship of victim to the offender. CLASS IV UNIVERSE: All homicides in Chicago Police Department murder analysis files from 1965 through 1981. NOTE: Because the data were collected in many stages by many people over a long period of time, the codes used have undergone repeated reV1Slons. In most cases, these revisions have been added to the coding categories without changing the existing codes. Some variables were added to the study in later years. This is especially true of variables attempting to capture sentence information, which was very seldom present in the Chicago Police Department analysis reports. Geographical location was collected differently in different years. From 1971 through 1976, a north-south and east-west grid code was used. After 1976, an actual address was written on the codesheet. This address was later converted to a "pin map" location using the Census DIME Files, producing a new geographical data file.
