DATA COLLECTION DESCRIPTION

Jacqueline Cohen, Wilpen Gorr, and Piyusha Singh EXAMINATION OF CRIME GUNS AND HOMICIDE IN PITTSBURGH, PENNSYLVANIA, 1987-1998 (ICPSR 2895)

SUMMARY: This study examined spatial and temporal features of crime guns in Pittsburgh, Pennsylvania, in order to ascertain how gun availability affected criminal behavior among youth, whether the effects differed between young adults and juveniles, and whether that relationship changed over time. Rather than investigating the general prevalence of guns, this study focused only on those firearms used in the commission of crimes. Crime guns were defined specifically as those used in murders, assaults, robberies, weapons offenses, and drug offenses. The emphasis of the project was on the attributes of crime guns and those who possess them, the geographic sources of those guns, the distribution of crime guns over neighborhoods in a city, and the relationship between the prevalence of crime guns and the incidence of homicide. Data for Part 1, Traced Guns Data, came from the City of Pittsburgh Bureau of Police. Gun trace data provided a detailed view of crime guns recovered by police during a two-year period, from 1995 to 1997. These data identified the original source of each crime gun (first sale to a non-FFL, i.e., a person not holding a Federal Firearms License) as well as attributes of the gun and the person possessing the gun at the time of the precipitating crime, and the ZIP-code location where the gun was recovered. For Part 2, Crime Laboratory Data, data were gathered from the local county crime laboratory on guns submitted by Pittsburgh police for forensic testing. These data were from 1993 to 1998 and provided a longer time series for examining changes in crime guns over time than the data in Part 1. In Parts 3 and 4, Stolen Guns by ZIP-Code Data and Stolen Guns by Census Tract Data, data on stolen guns came from the local police. These data included the attributes of the guns and residential neighborhoods of owners. Part 3 contains data from 1987 to 1996 organized by ZIP code, whereas Part 4 contains data from 1993 to 1996 organized by census tract. Part 5, Shots Fired Data, contains the final indicator of crime gun prevalence for this study, which was 911 calls of incidents involving shots fired. These data provided vital information on both the geographic location and timing of these incidents. Shots-fired incidents not only captured varying levels of access to crime guns, but also variations in the willingness to actually use crime guns in a criminal manner. Part 6, Homicide Data, contains homicide data for the city of Pittsburgh from 1990 to 1995. These data were used to examine the relationship between varying levels of crime gun prevalence and levels of homicide, especially youth homicide, in the same city. Part 7,

Pilot Mapping Application, is a pilot application illustrating the potential uses of mapping tools in police investigations of crime guns traced back to original point of sale. NTC. It consists of two ArcView 3.1 project files and 90 supporting data and mapping files. Variables in Part 1 include date of manufacture and sale of the crime gun, weapon type, gun model, caliber, firing mechanism, dealer location (ZIP code and state), recovery date and location (ZIP code and state), age and state of residence of purchaser and possessor, and possessor role. Part 2 also contains gun type and model, as well as gun make, precipitating offense, police zone submitting the gun, and year the gun was submitted to the crime lab. Variables in Parts 3 and 4 include month and year the gun was stolen, gun type, make, and caliber, and owner residence. Residence locations are limited to owner ZIP code in Part 3, and 1990 Census tract number and neighborhood name in Part 4. Part 5 contains the date, time, census tract and police zone of 911 calls relating to shots fired. Part 6 contains the date and census tract of the homicide incident, drug involvement, gang involvement, weapon, and victim and offender ages. Data in Part 7 include state, county, and ZIP code of traced guns, population figures, and counts of crime guns recovered at various geographic locations (states, counties, and ZIP codes) where the traced guns first originated in sales by an FFL to a non-FFL individual. Data for individual guns are not provided in Part 7.

UNIVERSE: Parts 1-5 and 7: Guns used in the commission of crime in Pittsburgh, Pennsylvania, between 1987 and 1998. Part 6: Homicide victims in Pittsburgh, Pennsylvania, between 1990 and 1995.

NOTE: (1) Part 7 is a PKZip archive that illustrates how select data from this project can be used with mapping software. The 92 files, including two project files, were created with ArcView 3.1. Users should extract this zipped archive into a directory called "C:batf." Once the archive has been extracted onto the local drive, users should open the ArcView project file called batf-pgh-nij.apr to view the sample files. Additional information about this application can be found in the appendix to the codebook. (2) The user guide and codebook are provided by ICPSR as Portable Document Format (PDF) files. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided on the ICPSR Web site.

ICPSR CODEBOOK NOTES

1. ICPSR recoded system missing to 9-series and labeled them "Unknown" in all parts.

2. Information about how state BATF and FIPS codes link to state abbreviations in Part 1 can be found in the Appendix of this codebook.

3. The variable PO_BYR (Person Possessing Gun Birth Year) in Part 1 has two cases with the value 96. For these same two cases the variable REC_YR (Recovery Year) is also 96 and the variable CKPOAGE2 (Possessor Age at Recovery) is missing. In the Final Report for this project the principal investigator did not use cases where CKPOAGE2 was missing when reporting data about possessor age. Therefore, ICPSR did not resolve the discrepancy found in PO_BYR for these two cases.

4. For Part 1, value labels for the variable MNF (Manufacturer Code) can be found in the Appendix of this codebook.

5. For Parts 2-4, value labels for the variable CALIBER (Gun Caliber) can be found in the Appendix of this codebook.

6. For Part 5 the variable INCIDNUM (Sequence # Non-Duplicate 911 Calls) is a six-digit unique record identifer, where the first two digits are the year of the 911 call. The variable INCID (Sequence # Non-Duplicate Calls w/in Year) is a four-digit record identifier that is unique within each of the five years for which there are data (1992-1996).

7. Several year variables are recorded as a two-digit value in the data. Users interested in using these variables for analysis of duration will want to convert the year to a four-digit value. Users can use one of the following examples after the SPSS or SAS syntax files have been used to read the ASCII data file into SPSS or SAS, respectively. A display format is given but users can elect to use a format of their choice. A listing of the original values and created values is shown after the conversion.

Example to convert to a MMMYYYY format using SPSS:

compute newreqyr=req_yr+1900. compute reqdte=date.moyr(req_mo, newreqyr). format reqdte (adate6).

list req_mo req_yr newreqyr reqdte.

REQ_MO REQ_YR NEWREQYR REQDTE

7 95 1995.00 JUL 1995

Page 2 ICPSR 2895

Example to convert to a MM/YYYY format using SAS:

Because the MDY function requires a month, day and year argument, users must hardcode a value for the day. In this example the day value in the MDY function is hardcoded as 15.

newreqyr=req_yr+1900; reqdte=mdy(req_mo, 15, newreqyr); format reqdte mmyys9.;

put req_mo req_yr newreqyr reqdte;

REQ_MO REQ_YR NEWREQYR REQDTE 7 95 1995 07/1995

Pilot Arcview Application for Mapping Sources of Crime Guns

1 Revised: January 2001 Traced Crime Guns Mapping Application 95-IJ-CX-0075

README.TXT batf-pgh-nij.zip

The pkzip file, batf-pgh-new.zip contains Arcview 3.1 project files for mapping gun traces originating from the Pittsburgh Police and the Philadelphia Police during 1995 and 1st half of 1996. This is a pilot application illustrating the potential uses of mapping tools in police investigations of crime guns traced through the National Tracing Center of the Bureau of Alcohol, Tobacco and Firearms (BATF) in the U.S. Treasury Department.

The files have been compressed with full directory pathname. When the files are extracted they MUST BE extracted to the designated path: c:\batf. In pkzipw, select c:\ as the destination directory and set PREFERENCES to "Create Directory." The extraction process should create the necessary directory and copy all unzipped files to that new directory.

To open the project, first open Arcview. Then open the project file batf-pgh.apr from directory c:\batf.

The mapping application includes various counts of the geographic locations (aggregated to states, counties, and zipcodes) where the traced guns first originated in sales by a Federal Firearms Licensee (FFL) to a non-FFL individual. Only the counts by zipcode and state of origin are aggregated directly from the available BATF data. Counts by county are approximated here for illustrative purposes by apportioning zipcode and state data to counties. (The county of origin could be obtained exactly in ArcView using data on the full street address of the original point-of-sale FFL.)

2 Revised: January 2001 Traced Crime Guns Mapping Application 95-IJ-CX-0075

Count Data by Geographic Area

The raw data include basic information for crime guns recovered by police in 1995 or the first half of 1996, and traced by police through the National Tracing Center of the U.S. Bureau of Alcohol, Tobacco, and Firearms (BATF). Trace results generally track the gun from the point of manufacture or import, through various Federal Firearms License holders (FFL) and to the first point of sale to a non-FFL. With the data available to this project, it was possible to obtain direct counts of traced guns by the police department requesting the trace and the zipcode and state for the Federal Firearms License (FFL) holder who originally sold the gun to a non-FFL individual.

The full data maintained by the National Tracing Center include more detailed information about the full street address of the FFL at the first point of sale and the location where the crime gun was recovered by police. This more detailed information could be used to identify the originating FFls by other geographic areas like county, place (municipality or city) and census tract, as well as locating the crime gun recoveries within specific neighborhoods of a city. For illustrative purposes, the mapping application presented here aggregates crime guns citywide for the Pittsburgh and Philadelphia police departments. Counts by county of the original point of sale are approximated by apportioning the available zipcode and state information to counties.

Variables in *.dbf files

In addition to the mapping data information, the Arcview project includes a number of data files in Dbase IV *.DBF format. The illustrative data are based on crime guns recovered by the Pittsburgh and Philadelphia police during 1995 and the first half of 1996 and traced through the National Tracing Center. The *.DBF files include basic identifying and mapping information about specific geographic areas (states, counties, and zipcodes). They also include counts (actual for states and zipcodes, and estimates for counties) of the number of crime guns that are traced back to each area as the original point of sale. The table on the next page describes the available variables.
