DATA COLLECTION DESCRIPTION
Carolyn Rebecca Block, Richard L. Block, and the Illinois Criminal Justice Information Authority HOMICIDES IN CHICAGO, 1965-1995 (ICPSR 6399)
SUMMARY: These datasets contain information on every homicide in the murder analysis files of the Chicago Police Department for the years 1965-1995. For the victim-level file, Part 1, data are provided on the relationship of victim to offender, whether the victim or offender had previously committed a violent or nonviolent offense, time of occurrence and place of homicide, type of weapon used, cause and motivation for the incident, whether the incident involved drugs, alcohol, gangs, child abuse, or a domestic relationship, if or how the offender was identified, and information on the death of the offender(s). Demographic variables such as the age, sex, and race of each victim and offender are also provided. The victim-level file contains one record for each victim. Information for up to five offenders is included on each victim record. The same offender information is duplicated depending on the number of victims. For example, if a sole offender is responsible for five victims, the file contains five victim records with the offender's information repeated on each record. Part 2, Offender-Level Data, is provided to allow the creation of offender rates and risk analysis that could not be accurately prepared using the victim-level file due to the repeating of the offender information on each victim record. Offender variables were reorganized during the creation of the offender file so that each known offender is associated with a single record. A majority of the variables in the offender-level file are replicas of variables in the victim-level file. The offender records contain demographic information about the offender, demographic and relationship information about the offender's first victim (or sole victim if there was only one), and information about the homicide incident. Information pertaining to the homicide incident such as location, weapon, or drug use are the same as in the victim-level file. In cases where the offender data were completely missing in the victim-level data, no offender records were generated in the offender-level file. The offender-level data do not contain information about the victims in these cases. Geographic variables in both files include the census tract, community area, police district, and police area.
UNIVERSE: All homicides in the murder analysis files of the Chicago Police Department from 1965 through 1995. NOTE: (1) The codebooks, data collection instrument, and maps are provided as Portable Document Format (PDF) files. The PDF format was developed by Adobe Systems Incorporated and can be accessed using the Adobe Reader.

OVERVIEW: THE CHICAGO HOMICIDE DATASET
The Chicago Homicide Dataset, one of the largest and most comprehensive datasets on violence ever collected in the United States, contains detailed information on every homicide in Chicago police records from 1965 to 1995 -- over 100 variables and nearly 23,000 homicides. Unburdened by many of the limitations inherent in national statistics (the Supplementary Homicide Reports of the UCR), the Chicago Homicide Dataset is organized so that questions about victims, offenders, or incidents (and inter-relationships between them) can be answered. For example, it is possible to conduct an analysis of the risk of death and the risk of becoming an offender for a specific type of homicide (such as street gang-related, spousal, or instrumental) for specific racial/ethnic, age, and gender groups, and within specific neighborhoods, and to follow these patterns for almost 30 years.
This unique set of data has been compiled with the close cooperation of the Chicago Police Department over many years by Carolyn Rebecca Block of the Illinois Criminal Justice Information Authority and Richard L. Block of Loyola University Chicago. Initially, the data collection was established by Richard Block and Franklin Zimring of the University of Chicago Law School, working with the Chicago Police Department. Margo Wilson and Martin Daly of McMaster University also have contributed to data collection, and numerous researchers and policy makers have used the data for policy analysis or causal modeling. For a partial list of publications using the Chicago Homicide Dataset, see Appendix E.
Support for the Chicago Homicide Project has been provided over the years by the Illinois Criminal Justice Information Authority, Loyola University Chicago and the University of Chicago Law School, under grants from the National Institute of Justice, the Ford Foundation, the Bureau of Justice Statistics, the National Institute of Mental Health, the Harry Frank Guggenheim Foundation, the National Institute of Occupational Safety and Health and most recently, the Joyce Foundation. The Illinois Criminal Justice Information Authority has maintained the Chicago Homicide Dataset since 1979.
Since 1988, the dataset has been available to the general public from the National Archive of Criminal Justice Data (NACJD) of the Inter- university Consortium for Political and Social Research (ICPSR) at the University of Michigan in Ann Arbor. Each time the dataset is updated with new years of data, all cases for previous years are also updated, and a copy of the entire dataset is deposited in the Archive. The dataset may be purchased from the Archive on CD-ROM or computer tape. The 1965 through 1994 version of the dataset is available from the Archive on a CD-ROM produced by the National Institute of Justice (NIJ) as one of a collection of datasets on violence from around the nation. The most current version of the dataset (1965 to 1995) is accessible on the Internet from the Archive's website: http://www.icpsr.umich.edu/NACJD. Before archiving the data, a number of variables that measure confidential information that cannot be released are stripped from the dataset. These stripped variables include individual identifiers, narrative detail, and street address. Page 2 ICPSR 6399
HISTORY:
The establishment of the Chicago Homicide Dataset, and the collection of data from 1965 to 1978, were carried out over several years under grants from the Ford Foundation and the National Institute of Mental Health to the University of Chicago Law School. In 1984, under a grant from the Bureau of Justice Statistics to the Illinois Criminal Justice Information Authority, three years were added to the data (1979 to 1981), the years from 1971 to 1978 were updated, and a comprehensive codebook was published as a guide to the dataset (CHICAGO HOMICIDE CODEBOOK by C.R. Block, ICJIA, 1984, revised 1987). Updating includes adding to the dataset any additional investigation information, especially when a case has been cleared since the last wave of data collection.
Data in the years 1965 to 1970 were not updated or cleaned in 1984, because of difficulties in the identification of specific cases. However, in 1989 and 1990, supported by a grant from the Harry Frank Guggenheim Foundation to McMaster University, the case identification problem was solved, and all 1965 to 1990 cases were cleaned and updated. In addition, data from 1982 through 1989 were added to the file, cases from 1965 to 1981 were updated, and a number of variables ("drug use" and "drug related" variables, specific circumstances of domestic altercations and variables indicating expressive versus instrumental motive) were tested, checked for coder reliability and coded or recoded consistently throughout the 25 years. Most recently, in 1994 and 1995, funded by a grant from the Joyce foundation, the 1965 through 1989 data were further cleaned and updated and the years 1990 to 1995 were added to the dataset.
DATA AND DATA COLLECTION:
The Chicago Homicide Dataset includes all homicide cases recorded by the Chicago Police Department, except those deemed "justifiable." Homicides classified as justifiables by police investigation are separated from other homicides, because they are not considered crimes. The records for justifiable homicides are retained in police files for a very short time. Offender information is not recorded because there are no offenders in justifiable homicides. Self defense alone does not constitute a justifiable homicide. There must be two RDNUMBERs (unique number assigned to each incident) in order to have a justifiable homicide: one for the offense that was committed against the person acting in self defense and one for the justifiable homicide. Also, an exceptional clearance (e.g., not enough evidence to prosecute, self defense, death of the offender(s), witnesses not credible) does not classify a homicide as justifiable.
The source of the data is police investigation files. Based on the original investigation report, Detective Division staff in the Crime Analysis Unit fill out a Murder Analysis Report (MAR) for each homicide, using a coding scheme similar to that of the Chicago Homicide Dataset, to measure various factors of the case (e.g., causal factor, relationship, location and weapon). See Appendix F for a sample copy of an MAR and Appendix A for a list of the original MAR fields as received from CPD. Victims and offenders are those ICPSR 6399 Page 3
identified by police investigation. Victims are the people who died. Offenders include all those known to the police, whether or not arrested. Offenders in cases that have been cleared exceptionally are also counted (e.g., offender died or charges were rejected by the Assistant State's Attorney).
In general, these homicides are defined at the police investigation stage, without regard to later criminal justice decisions (though some disposition data are included in earlier years of the dataset). The standard of proof required by the courts is not the same as the "preponderance of evidence" standard required at the police level. For example, a 1970s police investigation determined that an arson homicide, in which 23 nursing home residents were killed, was perpetrated by a cleaning woman employed by the nursing home. Although there was enough evidence to prosecute the cleaning woman, she was not convicted. Nonetheless, these 23 elderly victims are included in the Chicago Homicide Dataset -- with the cleaning woman as the offender -- because by police standards of proof, the cleaning woman did indeed commit the homicides.
The ultimate source of all information for all years is the MAR, a one-page summary of each homicide, which has been maintained since 1965 by the Crime Analysis Unit of the Chicago Police Department. When the coders have a question about the MAR information, or they need clarification about what happened in a particular case, officers in the Crime Analysis Unit advise them as to the correct codes and definitions. All coding and data entry are carried out in the Crime Analysis Unit.
Since 1982, the Chicago Police Department has maintained data on murder cases in an automated system called RAMIS. The Crime Analysis Unit downloads RAMIS information to .dbf (dBASE) files, which Authority staff convert into SPSS data entry files. Coders then, working at CPD, check the RAMIS data against the MAR for each case and add variables, additional codes and narrative not coded in RAMIS.
Data are received from CPD in two separate files. One file contains offender demographics and has one record per offender. The victim demographics and the rest of the variables are received in a victim-level file. The two data files are linked by a unique identifier for each victim, the homicide file number (HOMINUM). For a list of the original MAR fields as received from CPD, see Appendix A. The file containing the offender demographics is converted to a victim-level format, then merged with the victim-level file, by HOMINUM. Multiple offender information is appended to each victim record, up to five offenders. Information on each of six or more offenders is recorded in the narrative. If the incident involves more than one victim, there will be more than one record for that case, and the records will be linked by the same RDNUMBER. So that offender rates and trends may more easily be calculated, we have also created an offender-based version of the Chicago Homicide Dataset. This includes the same information as the victim-based dataset, but has one record per offender. In multiple offender homicides, the same incidents are linked by RDNUMBER, and the same victims are identified by HOMINUM. Page 4 ICPSR 6399
Chicago Police Department data and the Chicago Homicide Dataset may differ for two reasons -- because cases may become known to the police months or even years after the initial occurrence, or may be delayed because of a lengthy investigation or because the victim died some time after the attack, monthly or yearly totals based on the Chicago Homicide Dataset may not equal official CPD totals, which are usually based on booking date. The variable BOOKYEAR measures the year the homicide was booked by CPD. This variable is important for understanding year-to-year changes in variable definitions and changes in police area and district boundaries. When data for a new year are collected, we also update the information on any earlier cases that have been cleared in the interim. Updating for cases booked in a given year will increase the number of Dataset cases occurring in previous years and decrease the number of cases in recent years; therefore, the most recent years in the dataset should be considered preliminary.
Coders are supervised closely and trained continuously. ICJIA staff run standard cleaning programs on the data to automate the cleaning process and to detect coding errors. Some examples of cleaning rules are the following: if the victim's relationship to the offender is "son," then the victim should be male and younger than the offender; all cases coded "drug business motive" should also be coded "instrumental"; if the victim was "killed while committing a predatory crime," the specific crime should be coded under the "800" codes of the causal factor variable when applicable; if "victim is a prostitute" is coded under the causal factor variable, then the victim's relationship to the offender should be prostitute and the offender's relationship to the victim is probably pimp, client or prostitute. The programs for these "cleaning runs" are listed in Appendix D.
The values "Missing" and "Unknown" are used to indicate that information for a certain variable is not known to the police according to the MAR, or the variable does not apply to the circumstances of a particular case. For example, if the race variable for the third offender is coded "Missing", this means that either the race of the third offender is not known to the police or a third offender was not involved in the incident.
Though the Chicago Homicide Dataset contains data compiled over many years, with some changes in definition over time, every effort has been made to produce key variables in which the definitions and interpretation are consistent over the entire time span. For example, over the years, the Chicago Police Department has employed five different coding systems for race/ethnicity; instead of including all five, we include only one in the working version of the dataset (used for daily analysis by Authority staff) and in the version sent to the Archive: VICRACE is a composite variable measuring the race/ethnicity of the victim, which takes into account all the different CPD codes employed over the years and recodes them into categories for non-Latino white, non-Latino black, Latino, and Asian/other. See RECODES program in Appendix D4. As another example, prior to 1982 CPD did not use the RAMIS codes LOCATION and WEAPCAL. In order to measure the location of the incident and the type of weapon used from 1965 through 1981, Richard and Carolyn Block developed the variables ICPSR 6399 Page 5
BODLOCAN and TOWEAPON. Later, in order to make the codes consistent throughout the dataset, the Block codes for location were recoded to match the CPD codes. The variable WEAPON and its counterparts were generated from TOWEAPON and WEAPCAL to capture the information in both variables. With future cleaning of the data, WEAPCAL will be coded for the years prior to 1982. The Block codes are no longer part of the dataset. They, along with the old race/ethnicity codes and any other variables that are no longer employed in the dataset, are maintained in the complete backup file of the Dataset at the Authority for purposes of documentation and reference. See Appendix B for a record of the various race/ethnicity codes employed by CPD over the years and Appendix C for the Block code TOWEAPON.
The current version of the dataset clarifies and expands upon past versions in a number of ways. Specifically, this version's codebook documents the many new variables that have been created. Such variables were created with the intention of making the Dataset more comprehensive and "user-friendly." Note especially the following created variables which have been added to the dataset:
SYNDROME: Perhaps most significantly, this dataset and codebook include variables like this one which have been in existence for some time but have not been included in an archived version of the dataset. SYNDROME is a useful variable that provides the researcher with a quick answer to the question: "What were the broad circumstances surrounding this homicide?" SYNDROME was created by combining elements of both relationship and motive variables to create values such as "gang-related", "instrumental", "spousal attack", "child abuse" and "other family, expressive".
DRUGTOT & INTOXTOT: These two variables were created in order to provide succinct information about the prevalence of alcohol and drug use and drug motive, in various combinations, in a homicide.
SEXRACE: This variable was created to make the dataset more convenient to use. For example, SEXRACE informs the researcher of both the gender and the race/ethnicity of the homicide victim. Five additional variables like this one exist in the dataset to measure the gender and race/ethnicity of up to five offenders.
PLACE and counterparts, WEAPON and counterparts: These summary variables categorize the values of LOCATION and WEAPCAL into groups that possess similar characteristics. For example, POUTDOOR groups together all locations that are outdoors, and WHANDGUN groups together all weapons that are handguns. CALIBER is a very important weapon variable for the analysis of homicides committed with a firearm. It has been extremely useful in examining the surge of homicides in the early 1990s.
INVEST (1-5): This variable measures the outcome of the police investigation for up to five offenders in the years 1990 and after. Data collection in the years prior to 1990 included information on only the first offender. You will notice that the dataset consists of two additional variables that measure this same factor. INVSTGN contains information for the years 1965 to 1981, and INVEST contains information for the years 1982 to 1989. This is because data were Page 6 ICPSR 6399
collected in a different manner in those two periods. For example, INVEST separates "exceptional clearance" into two separate values (death of offender and bar to prosecution), whereas INVSTGN groups them together. The differentiation between the two elements of "exceptional clearance" provides a more descriptive measurement of the outcome of the police investigation. With the addition of the 1990 data a new variation of INVEST was created to include information on up to five offenders.
Many pre-existing variables are no longer included in the working and archived versions of the dataset, mainly because of inconsistencies in coding throughout the years and lack of information in the MARs. SAMESUR measured whether the victim and offender(s) had the same surname, SAMEADD measured whether the victim resided with the offender(s), MARITAL measured the marital status of the victim and offender(s) and DISP measured the court or other disposition of each offender. BEAT was eliminated because of the constant changes in police beat boundaries. When relevant and available, much of this information is now recorded in REMARKS. A record of variables like these that are no longer part of the current dataset is maintained in old codebooks and backup files of earlier versions of the dataset.
ON THE NATIONALLY ARCHIVED VERSION:
The complete dataset contains 122 variables; the Archive version contains 115. Certain variables were excluded from the Archive version, because to include them would violate standards of confidentiality. For example, the variable ADDRESS, which measures specific city addresses, has been omitted from the Archive version of the dataset. Those researchers interested in geocoding this material can use the included (census tract) CENTRACT and (community area) COMAREA variables. The variables RDNUMBER, REMARKS, OUREMARK, XCOORD and YCOORD have also been left out of the Archive dataset. The variable WEAPCAL was omitted from the Archive version because the same detailed information is provided by the individual weapon type variables (WEAPON, WARSON, WAUTOMAT, etc.).
ORGANIZATION OF THIS CODEBOOK:
This codebook was designed especially for use by coders of the Chicago Homicide Dataset, but may also be used for reference by users of the dataset. The major section of this document is the codebook itself, consisting of variable names, values, variable and value labels, and coding instructions. The codebook is divided into two parts, one documenting coded variables and the other created variables. Endnotes are included to further explain coding instructions. The Appendix includes a list of the variables received from CPD and those in the complete working version of the Chicago Homicide Dataset, documentation of earlier race/ethnicity and weapon codes that are no longer used, the SPSS programs used to generate the created variables in the dataset and detect coding errors, a list of publications based on the dataset, an example of the CPD MAR form, Chicago police district maps and a summary of the changes in district boundaries over the years, and a Chicago community area map.

CHICAGO HOMICIDE CODEBOOK
GENERAL CODING INSTRUCTIONS:
- Read the entire Murder Analysis Report (MAR) before coding.
- Using the codes and providing a detailed narrative, attempt to capture as much information as possible about each case.
- Use all available evidence, including the "Statement of Facts" of the CPD investigator.
- Always code what is relevant to the HOMICIDE INCIDENT. For example, if the victim is a prostitute killed by her boyfriend, the victim's relationship to the offender is girlfriend, not prostitute.
- When in doubt, use the police investigator's definition, as recorded in the MAR.
- If there is anything unusual or confusing about the coding of the case, note it in the narrative.
- If there are more than five offenders involved in the homicide, record all information on all offenders over five in the narrative.
PART I : Variables Coded Directly from the MARs
The variables in this section of the codebook are coded and not created by programs. Some are CPD RAMIS codes. Others were developed by staff working on the Dataset in order to capture the maximum amount of information about each homicide. Refer to this section of the codebook when coding new years of data as received from CPD.
Code values "Missing" and "Unknown" when information for a variable is not available, either because the information is not known to the police according to the MAR, or because the variable does not apply to the circumstances of a particular case.

Variable: CIRCUM Columns: 116 Label: CIRCUMSTANCES--EXPRESSIVE VERSUS INSTRUMENTAL
What was the OFFENDER'S primary goal at the time of the incident? Code according to the offender's IMMEDIATE primary motive, regardless of the actual consequences (even if a bystander, not the "intended" victim, was killed).
0 No information 4 Both expressive and instrumental 1 Fight or brawl 5 Sexual assault 2 Other expressive 6 Other motive 3 Instrumental
1. Fight or brawl: An altercation in which both the intended victim and the offender participated (e.g., street gang fight, barroom brawl, domestic fight, bystander killed in crossfire)(44). Page 20 ICPSR 6399
2. Other Expressive: Offender's immediate and primary goal was to hurt, kill or maim either the actual victim or someone else. No clear evidence of a fight. Not a contract killing. This may include spouse abuse, child abuse, elder abuse, revenge or retaliation (saving "face" or honor), arson to injure or for revenge, "hate" killings (gay bashing, racial killings), "random" killings (firing a gun into the street), murder/suicide, mental disorder, bystander killed by "accident"(45).
3. Instrumental Motive: Offender's immediate and primary goal was to obtain money or property (e.g., robbery, burglary, attempted theft, blackmail, deceptive practice, insurance fraud, arson for profit, contract killing, ransom, drug business(46), organized crime).
4. Offender's immediate motive included BOTH expressive and instrumental aspects. Attempt to determine the PRIMARY motive - expressive or instrumental. However, if both motives were clearly present, code here. Record details in "Remarks".
5. Sexual assault murder: Offender's goal was sexual assault (any kind), of a male or female victim. Code even if sexual assault was only threatened or attempted.
6. Other Known Offender Motive: for example: mercy killing (euthanasia); medical treatment (e.g., malpractice, illegal abortion); suicide pact(47); offender actively escaping apprehension by police or security guard; witness or informant of crime is killed in retaliation; victim killed while interceding in a felony(48). Record details in "Remarks."
9. Not enough information to code offender's motive. No "altercation," "causative factor," or other relevant narrative in Murder Analysis Report (e.g., a body found on street, with no evidence of robbery).
Variable: MOTIVROB Columns: 117 Label: ROBBERY MOTIVE
Code according to the MAR. Robbery motive should also be coded as a causal factor.
0 Robbery not involved 1 Strongarm robbery (CAUSFACT 305) 2 Armed robbery (CAUSFACT 300) 3 Victim is a robber (CAUSFACT 850)

WEAPON VARIABLES:
Variable: WEAPCAL Label: WEAPON CALIBER/TYPE OF WEAPON USED (1982 and after)
Code the primary weapon that caused the death of the victim. Note any secondary weapon(s) in the narrative. NOTE: PRIOR TO 1982, A VARIABLE DEVELOPED BY THE BLOCKS (TOWEAPON) WAS USED TO CODE THE TYPE OF WEAPON. TO MAKE CODING CONSISTENT THROUGHOUT THE DATASET, WEAPCAL AND TOWEAPON WERE RECODED INTO SEVERAL INDIVIDUAL WEAPON TYPE VARIABLES (WEAPON, WAUTOMAT, WARSON, WCLUB, ETC.). THESE SUMMARY VARIABLES CAPTURE WEAPON INFORMATION FOR THE ENTIRE PERIOD ENCOMPASSED BY THE DATASET. SEE WEAPON90 PROGRAM IN APPENDIX D8 FOR THE CREATED WEAPON VARIABLES AND APPENDIX C FOR THE TOWEAPON CODES. ALTHOUGH THE ORIGINAL BLOCK WEAPON VARIABLE IS STILL AVAILABLE IN THE COMPLETE BACKUP DATA FILE AT THE AUTHORITY, WEAPCAL IS NOW USED FOR ALL YEARS.

PART II: Variables Generated by Recode Programs
The variables in this section of the codebook are created by running SPSS programs on already coded variables in the dataset. The generated variables consist of composite, summary and detailed variables. They provide a comprehensive record of each homicide and allow for detailed, descriptive analysis of the data.
The values "Missing" and "Unknown" indicate that information for a certain variable is not available, either because the information is not known to the police according to the MAR, or because the variable does not apply to the circumstances of a particular case.

OUTCOME OF POLICE INVESTIGATION:
The following variables measure the outcome of the police investigation of a case: whether a case was cleared by arrest or exceptional clearance and how an arrest took place. They are created from a series of dichotomous variables (OFFSU, OFFSCEN, OFFID, OFFIDIN, CLRDEXB), part of the original data file received from CPD. The original dichotomous variables can be found in Part I of this codebook.
Prior to "Bookyear" 1990, information for this variable was collected only for the first offender. The variable INVSTGN was used in "Bookyears" 1965 through 1981 and contains information on only the first offender. In "Bookyear" 1982, it was changed to better define the value that measures EXCEPTIONAL CLEARANCE, but it still only measured information for the first offender. In "Bookyear" 1990, the variables INVEST(1-5) were created to account for up to five offenders. The variables INVSTGN and INVEST, though not used anymore, were included in this section of the codebook for purposes of future cleaning of the data prior to 1990. The current variables INVEST(1-5) are not composite.
The dichotomous codes in the MAR account only for the first offender. Typically, if a homicide involves multiple offenders, the same code applies to all involved. However, there are times when a different outcome is specified for one or more of the offenders involved. For example, in a homicide that involved three offenders, one may have been arrested, while the other two are still at large and wanted by the police. ICPSR 6399 Page 61

RACE/ETHNICITY CODES
The following are various codes used by CPD over the years to measure race/ethnicity of the victim and offender(s) in a homicide. The current variables used by CPD (VRACE, OFN1RACE, OFN2RACE...) are in Part I of this codebook. Composite variables that contain race information for all the years in the dataset have been generated by a recode program. They can be found in Part II of this codebook (VICRACE, OFN1R, OFN2R...). The original variables as coded below for each "Bookyear" still exist in the complete Chicago Homicide Dataset backup file at the Authority.
Race/ethnicity codes used by CPD in "Bookyears" 1965 through 1970.
0 Race/ethnicity unknown 4 Mexican 1 White 5 Other 2 Negro 6 Other Latino 3 Puerto Rican
Race/ethnicity codes used by CPD in "Bookyears" 1971 through 1980.
0 Race/ethnicity unknown 5 Other 1 White 6 Other Latino 2 Negro 7 Oriental 3 Puerto Rican 8 American Indian 4 Mexican
Race/ethnicity codes used by CPD in "Bookyear" 1981.

APPENDIX C
WEAPON CODES
This variable (TOWEAPON) was developed by the Blocks and used to code type of weapon in the years prior to 1982. Since 1982, the CPD RAMIS code WEAPCAL has been used to measure weapon information. WEAPCAL is in Part I of this coebook. To make coding consistent throughout the dataset, WEAPCAL and TOWEAPON were recoded into several individual weapon type variables (WEAPON, WAUTOMAT, WARSON, WCLUB, etc.). These summary variables capture weapon information for the entire period encompassed by the dataset and are in Part II of this codebook. See WEAPON90 program in Appendix D8 for the created weapon variables. Although the original Block weapon variable is still available in the complete backup data file at the Authority, WEAPCAL is now used for all years.
Original Block weapon codes used in "Bookyears" 1965 through 1981.

RECODE AND CLEANING PROGRAMS
The following SPSS programs generate the created variables in Part II of this codebook. NOTE: EACH TIME YEARLY DATA ARE RECEIVED FROM CPD TO ADD TO THE DATASET, THE FILE MAY BE SLIGHTLY DIFFERENT (E.G., CHANGES IN VARIABLE NAMES, FILE FORMAT, ADDITION OF NEW VALUES). PLEASE MODIFY THE FOLLOWING PROGRAMS TO ACCOUNT FOR ANY CHANGES IN THE DATA.
1. FLATOFF
Run on the offender-based file as received from CPD, this program generates a victim-level file, which is then linked by HOMINUM to the victim-based file received from CPD. This program creates variables to allow for the measurement of information on up to five offenders.

APPENDIX G
Chicago Police Districts
The city of Chicago is divided into 25 police districts. In 1975, 1979 and 1982, the boundaries of some districts changed and new districts were created. In 1992, the number of police areas was reduced from six to five, but this did not affect district boundaries. Performing analysis of Chicago homicide data by district requires some caution. For example, it may appear that no homicides occurred in District 22 prior to 1975, but District 22 was not created until 1975. You may also find that the number of homicides apparently decreased or increased significantly in some districts after a certain year. This is misleading, however, because the boundaries of those districts changed, so that the years before and after the change are not comparable.
To make it easier to avoid such errors, we have included maps showing Chicago police district boundaries over the years. Please refer to the attached maps and the summary below as a guide to the changes in district boundaries. Take into account the changes in police district boundaries when looking at homicide trends over time in a particular district. NOTE: CPD TOTALS ARE BASED ON THE BOOKING DATE OF THE HOMICIDE. BOOKYEAR IS A KEY VARIABLE FOR UNDERSTANDING YEAR-TO-YEAR DISTRICT BOUNDARY CHANGES. CONSULT POLICE DISTRICT MAPS THAT ARE CONTEMPORARY TO THE "BOOKYEAR" OF THE HOMICIDE FOR INTERPRETATION. UNLIKE CHICAGO POLICE DISTRICT BOUNDARIES, CENSUS TRACT BOUNDARIES (VARIABLE CENTRACT) HAVE REMAINED CONSISTENT OVER THE YEARS AND MAY BE USED TO GEOCODE THE HOMICIDE DATA.
District 1 No changes.
District 2 No changes.
District 3 No changes.
District 4 No changes.
District 5 Boundaries changed to create District 22 in 1975.
District 6 Boundaries changed to create District 22 in 1975.
District 7 No changes.
District 8 No changes.
District 9 No changes.
District 10 No changes.
District 11 Northern boundary extended one block north in 1982.
District 12 Slight change in northern boundary in 1982. Page 122 ICPSR 6399
District 13 Northern boundary moved one block south in 1982.
District 14 Boundaries changed to create District 25 in 1982.
District 15 Boundaries changed to create District 25 in 1982.
District 16 No changes.
District 17 No changes.
District 18 No changes.
District 19 Boundaries changed to create District 23 in 1975.
District 20 Boundaries changed to create District 23 in 1975; changed again in 1979 to create District 24. (No change in 1982.)
District 21 Slight change in 1975-one square block moved to District 1.
District 22 Created from Districts 5 and 6 in 1975.
District 23 Created from Districts 19 and 20 in 1975; northern boundary moved two blocks south in 1979 when District 24 was created.
District 24 Created from District 20 in 1979.
District 25 Created from Districts 14 and 15 in 1982. * 1965-1974

ENDNOTES
1. Because of inconsistencies in the coding of this variable prior to 1982, it was removed from the dataset for the years 1965 to 1981.
2. See endnote 1.
3. Try to determine from the information in the MAR whether the basement was located in a public building or private residence.
4. Try to determine from the information in the MAR whether the garage was for public use or belonged to a private residence.
5. See endnote 3.
6. See endnote 4.
7. Code outpatient emergency clinics (e.g., Care Station) here, but code doctors' offices or clinics as 1306.
8. This indicates a fight between adults about the children. In cases where the child was the victim, code 915 (child abuse), or other appropriate code.
9. A fight or argument over liquor or drinking. Whether or not the participants have been drinking is not relevant to this code.
10. A fight or argument over drugs. This may include an altercation over possession, use, quality, cost, drug selling/territory, etc. Whether the participants have been USING illicit drugs is NOT relevant to this code.
11. An "altercation over money" is NOT robbery or attempted robbery.
12. Use this code when drug business was the motive for the incident. Without any other evidence, do not code based solely on information that the victim was a known drug dealer.
13. Definition of hate crime: member(s) of one group attack member(s) of another group for no other reason than the group membership (e.g., gay bashing, racial attacks, religious or ethnic attacks). If a hate crime was the ONLY motive, code it as the first causal factor. If the incident was a fight, brawl or argument between friends or acquaintances, but it was precipitated by a racial slur, code "Hate crime" under CAUSFAC2.
14. An "altercation over sex" is NOT rape or sexual assault. Also, determine if the actual issue was a triangle or sexual rivalry, and code accordingly.
15. The offender is jealous of real or imagined infidelity.
16. If the MAR code is "gang altercation," NEVER change it. You may, however, indicate another causal factor. Page 132 ICPSR 6399
17. In an arson murder, the second causal factor should ALWAYS be "900 (arson). Use the first causal factor to code the kind of situation that let to the arson (e.g., an altercation, burglary, insurance fraud, etc.). In an arson murder where the first causal factor is "undetermined" but the offender has been identified, CIRCUM should be coded "other expressive."
18. This is an argument centered on an accusation of a theft. If a victim is killed by a thief in the act, code instead 95 (attempted theft) or other appropriate code.
19. A triangle altercation differs from sexual rivalry and sexual jealousy in that there is clear evidence that infidelity was involved (not just the offender's perception).
20. For example, malpractice, illegal abortion.
21. Two people competing for or arguing over the affections of a third person, homosexual relationships included.
22. Code here if nature of altercation is not specified in MAR or if the specific code for a certain type of altercation does not exist. Also use this code if victim was killed as a result of witnessing another crime. Note details in the narrative.
23. Offender is actively escaping apprehension for a crime, by police or a security guard. The victim is a police officer, security guard, witness, or bystander. This code should NOT be used in cases of retaliation or revenge. Also code victim/offender relationship as officer/suspect, security guard/suspect, witness/suspect, as appropriate.
24. Use this code ONLY if specified in MAR. If there is evidence that the motive was gang-related or some other motive, CAUSFACT should be coded the appropriate code (e.g., 140), and CAUSFAC2 should be coded 500.
25. If the MAR code for causal factor is "retaliation", attempt to determine the reason for the retaliation (e.g., prior altercation, victim is a robber, victim is a rapist) and code as an additional causal factor.

41. See endnote 23.
42. See endnote 24.
43. See endnote 25.
44. If the choice is unclear between 1 (fight or brawl) and 2 (other expressive, code 2.
45. See endnote 44.
46. If the homicide involves drug selling/business (DRUGRELA=1), CIRCUM should always be coded "instrumental."
47. In cases where the offender has killed himself, code "suicide pact" only if there is evidence in the MAR of an actual agreement (pact) between victim and offender. Otherwise, it is considered "murder/suicide."
48. If victim is killed while attempting to break up a fight, code 1 or 2. Also code VICTINTR.
49. If MAR indicates "sexual perversion," determine what type of sex motive was involved. The code "sexual perversion" was once a value under CAUSAL FACTOR but is no longer used in the Dataset.
50. Cases coded "sexual perversion" in the MAR but NOT involving sexual assault should be coded here.
51. A rape or sexual assault of a prostitute should be coded 1 or 2, as appropriate.
52. A PRIOR drug transaction (e.g., the victim failed to deliver) is also included here.
53. For example, if the victim was a prostitute but prostitution was not a factor in the homicide, do not use "prostitute" as a relationship code. This also applies to gang members, drug pushers, homosexuals, etc. Page 134 ICPSR 6399
54. Use in all cases in which the victim or offender had committed or was in the process of committing a crime when the homicide occurred. Typically the corresponding relationship code should be police, security guard, witness, proprietor, employee, etc.
55. Use this code if victim was killed by a fellow gang members in a gang-related incident.
56. Use this code if victim was passive bystander killed in gang crossfire, was mistaken for a gang member or was killed by a gang member for some other reason in a gang-related incident.

93. Code when the BUSINESS is the motive for the incident (e.g., both victim and offender involved in dealing, victim killed as a bystander of a drug business hit, victim killed because he interfered with the business, victim killed during a drug transaction or because of a drug transaction). When using this code, CIRCUM should always be coded 3.
94. Examples: baby dies of malnutrition because parents high, offender was drug-crazed. Use this code if there is positive evidence that drugs were somehow involved in the incident but not in a way covered by codes 1, 2 or 3.
95. Examples: victim was found in room strewn with needles or other paraphernalia; victim was known dealer and found dead at usual place of business. Without any other evidence, do not code based solely on the fact that victim was a known drug dealer.
