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.

iv Introduction
Th is codebook was the basis for the collection of data on every hvmicide in Chicago Police Department (CPD) murder analysis repor~ flles from 1965 through 1981, a total of 12,875 incidents. The codebook will be helpful for those who want to use this data set for their own analysis, and for those interpreting the details of analysis conducted by others. In addition, the codebook will be useful to anyone designing a similar study of homicide. Data Collection Data collection for 1965-1970 began in 1968. Additional data collection continued periodically through 1982. It has been pos sible only with the close cooperation, over the years, of the Chicago Police Department, in particular, former Superintendent James Rochford, former Deputy Superintendent Michael Spiotto, former Homicide Division Commander Joseph DiLeonardi, Homicide/Sex Division Commander Rudolph E. Nimocks (now Commander of Area 4 Detective Division), former Superintendent Richard Brzeczek, Deputy Superintendent Thomas J. Lyons, Chief William Hanhardt, Lieutenant Michael Caccitola, Sergeant Timothy Tidmarsh and former Detective Patrick Conway. Homicide data from 1965 through 1976 were collected under the supervision of Franklin E. Zimring of the Center for Studies in Criminal Justice of the University of Chicago Law School, and Richard L. Block of Loyola University of Chicago. Data~collection was supported, in part, by PHS Grant No. 1R01M27575, NIMH, to the Center for Studies of Crime and Delinquency. -- Homicide data from 1977 and 1978 were collected under the su pervision of Richard .Block; collection of 1979 through 1981 data was supervised by Richard Block and Carolyn Rebecca Block, and was supported by Bureau of Justice Statistics Grant No. 3960D to the Illinois Law Enforcement Commission, now the Illinois Criminal Justice Information Authority. Those who participated in data collection and coding over the years included Ruth O'Brien-Perrin, John Piegore, Ronald Gilbert I Nancy Haverfield, Ted Nagengast, Barbara Gilloley and Keith Cooprider. Consistency of Codes Over Time Because the data were collected in many stages by many people over a long period of time, the codes used have undergone repeated revision. In most cases, these revisions added to the coding categories. They did not change the existing codes. For example, the coders of 1965 homicides began with a list of categories of weapon. When a coder came across a weapon not on the list, after consul tation with the coding supervisors, that weapon would be added to the list. In this way, the number of categories for weapon, relationship and place expanded until each has close to 100. Some of these categories, as it turned out, occurred only
1 once or twice. In actual analysis, it is easy to combine all of the codes into broader categories. Some variables were added to the study in later years. This is esp~cially true of variables attempting to capture sentence in format:on. which was very seldom present in the CPO analysis report. The best outcome information is "Outcome of Grand Jury or Preliminary Hearingll (column 69), which began to be collected in 1971, and had additional categories added in 1977. The "Codes" and the "Notes" sections of this codebook include details of available information by year. Geographical location was collected differently in different years. From 1971 through 1976, a north-south and east-west grid code was used. After 1976, actual address was written on the codesheet. This address was later converted to a "pin map" loca tion using the Census DIME file, producing a new geographical data file. This codebook does not apply to the new geographical file. For information about the geographic data, see Richard Block. For most years, data reflect information available in mid-1982, even though the data were originally collected earlier. For the years 1971 through 1978, Authority staff updated the coding by searching police department files for cases that had not been cleared at the time of the original coding, but were cleared by 1982. (Because of the ID used, this would have been very difficult to do for the years 1965 to 1970.) For these cas-es, additional a\·ailable information was collected. Information about case outcome, in particular, was updated. Organization of this Codebook The major section of this report is the codebook itself, con sisting of detailed coding instructions and categories for each piece of information gathered over the years. Since the coding was done by many people over a long period of time, categories were added to some variables and new variables were also added. Therefore, the codebook details specific categories or variables that apply to only some of the 1965 to 1981 years. These and other problems with data interpretation are detailed in the "Notes" section.
Following the "Codes II and the "Notes" sections, the report includes a listing of the program that created the SPSSx system file at the Authority. This is followed by frequency tables for all variables, including recoded, corrected, and constructed vari ables. In addition, the report includes a bibliography of publications that have used the Chicago homicide data.

24 Notes: Corrected, Recoded and Constructed Variables
Column Title Comments 1-3 ID For 1965 through 1910, the ID number in the CPD analysis report was not recorded here. Instead, an arbitrary number was assigned sequentially to each case. 4 Book Year 1965-1973 ... Last digit of the year 1974 ...... A 1975-1981 ... Last digit of the year The year in which the homicide became known to the police, which was not neces sarily the year in which the homicide oc curred. As the homicide study expanded from 6 to 17 years, the original one column code for this variable was altered as above. For year of occurrence, do not use this variable. Use YEAROCC (columns 79-80) instead. 9 Sex of In the SPSSx system file, the variable Victim SEXRACE combines gender and race/eth nicity information. 10 Race/ In the SPSSx system file, the variable Ethnicity of RACEV is a recode of this variable; RACEV Victim codes are consistently defined for all years. 14 Year This was not used at all in 1974. In Incident other years, the final digit of the year Occurred was entered. Do not use this variable. Use "Year of Occurrence" ins'tead (columns 79-80) . 21-22 Place or In the SPSSx system file, the variable Location PLACE3 recodes place types into three Where Body categories: (1) inside a nonresidence, was Found (2) inside a residence, and (3) out-of doors or in a vehicle. 23-24 Type of In the SPSSx system file, the variable Weapon WEAPON1 recodes weapon types into seven categories: (1) handgun, (2) long gun, (3) unknown type gun, (4) knife or cut ting instrument, (5) hands, feet, club, blunt instrument, (6) other type weapon, (1) weapon type unknown.

SEXl Gender of all offender(s) in each homicide. RACEOF1 The race/ethnicity of each offender, using RACEOF2 codes that are consistently defined for all RACFOF3 years.

41 Intoxicant In 1975, the CPD criterion for victim in- Involved? toxication changed. Before 1975, the criterion was the investigating officer's opinion. Beginning in 1975, the criterion was blood tests conducted by the Cook County Medical Examiner's Office. Code 3 is listed in all codebooks since 1965 as IICan't tell," but was used only in 1971, 1975, and 1977. In the SPSSx system file, Code 3 has been included in Code 0 (No Information) .
26 S;;oltunn Title Conunents 42-43 Relationship In 1965-1970, Relationship was coded Victim/Offender, not Offender/Victim. This has been corrected in the SPSSx system file. See RELATE10 and RELATE4 for exact recodes. 44 Altercation The use of codes 9 and 0 differed from Motive the definitions given here in 1965, 1966, 196 7, 19 71, 19 7 2 , 19 7 3 and 1974 . It is impossible to reconstruct this variable for these years. Also, sometimes in the early years, "Altercation over money" was coded for robbery murders, and "Altercation OVer sex" was coded for rape murders. For further information, see Authority files. Teen/Youth The CPO designates as a teen or youth Gang gang-related homicide any homicide in (Code 4) which the motive for the killing was re lated to gang acti vi ty . Although it is frequently stated in the press and else where that CPO uses gang membership as the criterion for classifying a crime as gang-related: thi~ is a misconception. CPO has used motive, not gang membership as the criterion since at least the mid-1970s and probably before. For ex ample, if witnesses say the offender as y;:ed the victim for his or her gang af filiation and then shot the victim, the murder would be counted as a gang murder, even if the victim was not a gang member. An innocent victim killed in the cross fire of a gang shoot out or the purposeful killing ot the innocent sister of a gang member to punish the gang member would both be classified as teen/youth gang related. On the other hand, if two gang members enter into an altercation over some subject not related to the gangs and one kills the other, the murder would not be counted as a gang murder. Therefore, gang membership is !l.2.1 a criterion for classifying a homicide as gang-related. In a questionable case, the decision to classify a homicide as teen/youth gang related is conservative. If no clear evi dence of a gang-related motive exists, the case is not classified as gang related. The ages of the offender and victim are not criteria in the teen/ youth gang decision. For more detail, see "Lethal Violence in Chicago. II 27 Column Title Comments
45-47 Motive: The SPSSx system file contains the fol Robbery lowing constr~oted variables for the Motive: analysis of the circumstances or Burglary precipitating event of the homicide: Motive: Sex FELONY Coded 1 if the homicide was a robbery (armed or strongarm), burglary, sexual assault of a male, or sexual assault of a female. FIGHT Coded 1 if the homicide was not a felony (see above) and the victim/offender relationship was-not a mystery. PRECIP This variable combines all available in formation about the events that precipitated the homicide. A rape homicide (male or female sexual assault) that was also a robbery and/or a burglary is coded here as a rape homicide (code 2) . A robbery homicide that was also a burglary is coded here as a robbery (code 3) .
47 Motive: Police desis;nation of "Sex Perversion" in Sex the analysis report (code 1) is not reli able before 1971. It is impossible to distinguish between homosexual rape and murder of homosexual friends. Also, before 1978, code 1 was used for murders of females as ",rell as for murders for m~les. II Rape II (Code 2) was used in some cases of a male vict'im. In the SPSSx system file, the variable II Rape II dif ferentiates between sexual assault of males (code 1) and females (code 2) be tween 1971-1981.
49 Number of This information requires some cleaning Offenders because II Number of Oft'enders II ~,as coded 1 in about 10 percent of the cases in which the age, gender and race of a second of fender were known. The variable NUMOFNEW in the SPSSx system file corrects for this. If gender is known for 2 offend ers, NUMOFNEW12; if gender is known for 3 offenders, NUMOFNEW13; if gender is known for 4 offenders, NUMOFNEW14.
28 66 Investiga In 1977-1978, "Investigation" was coded 9 tion (no information) when an arrest had been made, but there was no information re garding the type of investigation. To analyze 1977-1978, cross-tabulate "Inves tigation" with II Clearance" (column 55).
70-76 Indictment These codes apply to 1971-1981. In Number 1965-1970, these columns were not used. In 1971-1976, they were used to code Drugs several sentence variables.

Crime? 79-80 Year of Year in which the incident, not the Occurrence death, occurred.
