Criminal Histories and Criminal Justice Processing of Drug Use Forecasting (DUF) Sample Members in Washington, DC, 1989-1991 (ICPSR 6122)

Released/updated on: 2006-01-12
Geographic coverage: United States
Time period: 1989-01-01--1991-12-31
These data provide information on the relationship between arrestee drug tests and future criminality once other risk factors, such as prior criminal history, are accounted for. Also explored is whether the association between drug test results and future offending varies depending upon the attributes of individual offenders. The dataset contains information drawn from the Pretrial Services Agency (PSA) in Washington, DC, and the National Institute of Justice's Drug Use Forecasting (DUF) program. Data are available from each source for 1989 and 1990 with subsequent arrest data provided by PSA through August 1991. The 1989-1990 data supplied by PSA contain information on criminal history and drug test results taken at the time of arrest. Data provided from the DUF program include drug test results from a sample of persons arrested as well as information obtained from arrestee interviews on items such as family and work status. The combined data contain the arrestees' demographic characteristics, arrest and charge information, prior criminal history, and subsequent offending. Drugs tested for include cocaine, opiates, methadone, PCP, amphetamines, barbiturates, marijuana, methaqualone, Darvon, and Valium. In addition, self-reported information regarding an individual's use of and dependency on these drugs is supplied. Demographic information includes age, sex, income, and employment status. Due to changes in the DUF measurement instrument from 1989 to 1990, the variables contained in the two data files are not completely identical.

Developing a Common Metric for Evaluating Police Performance in Deadly Force Situations in the United States, 2009-2011 (ICPSR 33141)

Released/updated on: 2014-06-18
Geographic coverage: United States
Time period: 2009-07-01--2011-09-30
This study developed interval-level measurement scales for evaluating police officer performance during real or simulated deadly force situations. Through a two-day concept mapping focus group, statements were identified to describe two sets of dynamics: the difficulty (D) of a deadly force situation and the performance (P) of a police officer in that situation. These statements were then operationalized into measurable Likert-scale items that were scored by 291 use of force instructors from more than 100 agencies across the United States using an online survey instrument. The dataset resulting from this process contains a total of 685 variables, comprised of 312 difficulty statement items, 278 performance statement items, and 94 variables that measure the demographic characteristics of the scorers.

Drug Use Forecasting in 24 Cities in the United States, 1987-1997 (ICPSR 9477)

Released/updated on: 1998-07-15
Geographic coverage: United States
Time period: 1987-06-01--1997-12-31
The Drug Use Forecasting (DUF) Program measures levels of and trends in drug use among persons arrested and booked in the United States. The data address the following topics: (1) types of drugs used by arrestees (based on self-reports and urinalysis), (2) self-reported dependency on drugs, (3) self-reported need for alcohol/drug treatment, (4) the relationship between drug use and certain types of offenses, and (5) the relationship between self-reported indicators of drug use and indicators of drug use based on urinalysis. Participation in the project is voluntary, and all information collected from the arrestees is anonymous and confidential. The data include the arrestee's age, race, gender, educational attainment, marital status, and the charge at the time of booking. The recently modified DUF interview instrument (used for part of the 1995 data and all of the 1996 and 1997 data) also collected information about the arrestee's use of 15 drugs, including recent and past use (e.g., 3-day and 30-day drug use) of each of these drugs, age at first use, and whether the arrestee had ever been dependent on drugs. In the original DUF interview instrument (used for the 1987 to 1994 data and part of the 1995 data), the information collected was the same as above except that the use of 22 drugs was queried, and the age at which the arrestee first became dependent on the drug was included. Arrestees also were questioned in the original instrument about their history of intravenous drug use, whether the consideration of AIDS influenced whether they shared needles, history of drug and alcohol treatment, their past and current drug treatment needs, and how many persons they had sex with during the past 12 months. Finally, arrestees were asked to provide a urine specimen, which was screened for the presence of ten drugs, including marijuana, opiates, cocaine, PCP, methadone, benzodiazepines (Valium), methaqualone, propoxyphene (Darvon), barbiturates, and amphetamines (positive test results for amphetamines were confirmed by gas chromatography). The Gun Addendum Data (Parts 27, 35, and 37) contain variables on topics such as arrestees' encounters with guns, whether they agreed or disagreed with statements about guns, gun possession, how they obtained handgun(s), whether they were armed with a gun at their arrest or during crimes, and if they had ever used a gun against another person. The Heroin Addendum Data, 1995 (Part 29) contains information that was formerly covered in the main annual file in 1992-1994, but in 1995 was revised and prepared as a separate dataset.

Estimating the Elasticities of Demand for Cocaine and Heroin with Data from 21 Cities from the Drug Use Forecasting (DUF) Program, 1987-1991 (ICPSR 6567)

Released/updated on: 2006-03-30
Geographic coverage: United States
Time period: 1987-01-01--1991-12-31
The objective of this research was to estimate the elasticity of the demand for cocaine and heroin with respect to the price. Price elasticity is the percentage of change in the dependent quantity corresponding to a one-percent change in price. The project involved the development of an econometric model to determine price elasticity, given that national- and city-level data on the consumption of cocaine and heroin are insufficient or nonexistent. The researchers circumvented this lack of data by partitioning the desired elasticity into the product of two elasticities, involving a measurable intermediate quantity whose relationship to the quantity of consumption could be modeled and estimated by measurable techniques. The intermediate quantity used for this project was the fraction of arrestees testing positive for cocaine or heroin as measured by the Drug Use Forecasting (DUF) System. From the Drug Enforcement Administration's (DEA's) System to Retrieve Information from Drug Evidence (STRIDE) data, expected purity was computed by regressing on log quantity and dummy variables for location and quarter. Price series were produced by finding the median standardized price per expected pure gram for each location and quarter. Variables for Part 1, National Data, include year, quarter, standardized prices for a gram of cocaine and a gram of heroin, and expected purity of cocaine and heroin. The Cities Data, Part 2, cover city, year, quarter, number of observations used to compute the median price of cocaine and heroin, standardized prices, and expected purity.

Evaluation of the Occurrence and Associative Value of Non-Identifiable Fingermarks on Unfired Ammunition in Handguns for Evidence Supporting Proof of Criminal Possession, Use and Intent, 2022-2024 (ICPSR 39306)

Released/updated on: 2025-01-07

The overall goal of this project was to answer the question of how often non-identifiable fingermarks occur on naturally loaded handgun ammunition and what range of associative values can be expected. This is a potential new source of evidence, as current forensic science practices set these fingermarks aside, leaving them unexamined. The project was successful, with highly significant findings showing that non-identifiable fingermarks with strong associative value are found frequently on loaded handgun ammunition. Utilization of this new source of evidence will require adjustment of long-standing forensic examination practices and balancing the level of effort required with the utility of the resulting associations. To do this one important follow-on step is replacing the labor-intensive research laboratory methods applied in this project with more efficient technologies available in forensic laboratories.

The project produced datasets that include images of 415 non-identifiable fingermarks in .tif format, and corresponding images with annotation of fingermark minutiae in .jpg format. The accompanying spreadsheets contain summary information for each of 1263 rounds of ammunition (number of identifiable and non-identifiable fingermarks found, the number of annotated minutiae for the marks, the handgun type - semi-automatic vs. revolver - and the caliber class), as well as the results from each of the handguns sampled.

Examination of Crime Guns and Homicide in Pittsburgh, Pennsylvania, 1987-1998 (ICPSR 2895)

Released/updated on: 2006-03-30
Geographic coverage: United States, Pennsylvania, Pittsburgh
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.

These data were collected using the National Electronic Injury Surveillance System (NEISS), the primary data system of the United States Consumer Product Safety Commission (CPSC). CPSC began operating NEISS in 1972 to monitor product-related injuries treated in United States hospital emergency departments (EDs). In June 1992, the National Center for Injury Prevention and Control (NCIPC), within the Centers for Disease Control and Prevention, established an interagency agreement with CPSC to begin collecting data on nonfatal firearm-related injuries in order to monitor the incidents and the characteristics of persons with nonfatal firearm-related injuries treated in United States hospital EDs over time. This dataset represents all nonfatal firearm-related injuries (i.e., injuries associated with powder-charged guns) and all nonfatal BB and pellet gun-related injuries reported through NEISS from 1993 through 2015. The cases consist of initial ED visits for treatment of the injuries. Cases were reported even if the patients subsequently died. Secondary visits and transfers from other hospitals were excluded. Information is available on injury diagnosis, firearm type, use of drugs or alcohol, criminal incident, and locale of the incident. Demographic information includes age, sex, and race of the injured person.

Time period: 2022-01-01--2022-12-31

These data were collected using the National Electronic Injury Surveillance System (NEISS), the primary data system of the United States Consumer Product Safety Commission (CPSC). CPSC began operating NEISS in 1972 to monitor product-related injuries treated in United States hospital emergency departments (EDs). In June 1992, the National Center for Injury Prevention and Control (NCIPC), within the Centers for Disease Control and Prevention, established an interagency agreement with CPSC to begin collecting data on nonfatal firearm-related injuries in order to monitor the incidents and the characteristics of persons with nonfatal firearm-related injuries treated in United States hospital EDs over time. This dataset represents all nonfatal firearm-related injuries (i.e., injuries associated with powder-charged guns) and all nonfatal BB and pellet gun-related injuries reported through NEISS from YYYY. The cases consist of initial ED visits for treatment of the injuries.

The NEISS-FISS is designed to provide national incidence estimates of nonfatal firearm injuries treated in U.S. hospital EDs. Data on injury-related visits are obtained from a national sample of NEISS hospitals, which were selected as a stratified probability sample of hospitals in the United States and its territories with a minimum of six beds and a 24- hour ED. The sample includes separate strata for very large, large, medium, and small hospitals, defined by the number of annual ED visits per hospital, and children's hospitals. The scope of reporting goes beyond routine reporting of injuries associated with consumer- related products in CPSC's jurisdiction to include all firearm injuries. The data can be used to (1) measure the magnitude and distribution of nonfatal firearm injuries in the United States; (2) monitor unintentional and violence-related nonfatal firearm injuries over time; (3) identify emerging injury problems; (4) identify specific cases for follow-up investigations of particular injury-related problems; and (5) set national priorities. A fundamental principle of this expansion effort is that preliminary surveillance data will be made available in a timely manner to a number of different federal agencies with unique and overlapping public health responsibilities and concerns. The final edited data will be released annually as public use data files for use by other public health professionals and researchers.

These public use data files provide NEISS-FISS data on nonfatal injuries collected from January through December each year.

NEISS-FISS is providing data on over 100,000 estimated cases annually. Data obtained on each case include age, race/ethnicity, sex, principal diagnosis, primary body part affected, consumer products involved, disposition at ED discharge (i.e., hospitalized, transferred, treated and released, observation, died), locale where the injury occurred, work-relatedness, and a narrative description of the injury circumstances. Also, intent of injury (e.g., unintentional, assault, self-harm, legal intervention) are being coded for each case in a manner consistent with the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) coding rules and guidelines.

Users are cautioned against using estimates with wide confidence intervals to make conclusions about point estimates. Firearm injuries have distinct geographic patterns and estimates can be imprecise or change over time when based on a small number of facilities.

NEISS has been managed and operated by the U.S. Consumer Product Safety Commission since 1972 and is used by the Commission for identifying and monitoring consumer product-related injuries and for assessing risk to all U.S. residents. These product- related injury data are used for educating consumers about hazardous products and for identifying injury-related cases used in detailed studies of specific products and associated hazard patterns. These studies set the stage for developing both voluntary and mandatory safety standards.

Since the early 1980s, CPSC has assisted other federal agencies by using NEISS to collect injury- related data of special interest to them. In 1992, an interagency agreement was established between NCIPC and CPSC to (1) collect NEISS data on nonfatal firearm- related injuries for the CDC Firearm Injury Surveillance Study; (2) publish NEISS data on a variety of injury-related topics, such as in- line skating, firearms, BB and pellet guns, bicycles, boat propellers, personal water craft, and playground injuries; and (3) to address common concerns. CPSC also uses NEISS to collect data on work-related injuries for the National Institute of Occupational Safety and Health (NIOSH), CDC.

In July 2000, NCIPC, in collaboration with CPSC, expanded NEISS to collect data on all types and causes of injuries treated in a representative sample of hospitals. This system is called the "NEISS All-Injury Program (NEISS-AIP)". These data provide the basis for national estimates of all types of nonfatal injuries treated in hospital emergency departments in the United States.

Beginning in 2019, CPSC initiated a redesign of the NEISS sample to update the sampling frame. The redesign includes adding and replacing hospitals. The redesign includes a resample based on more recent hospital information from the American Hospital Association, including the list of hospitals by hospital type. The prior sample was drawn in 1997. The NEISS sample goal is 100 hospitals; hospital recruitment and onboarding are ongoing. CDC and CPSC are continuing to release injury data while the onboarding is underway.

Gun Density, Gun Type, and the Dallas Homicide Rate, 1980-1992 (ICPSR 3145)

Released/updated on: 2006-03-30
Geographic coverage: United States, Texas, Dallas
Time period: 1980-01-01--1992-12-31
This study examined the relationships among trends in deadly gun violence, overall gun availability, and the availability of more lethal types of guns. Using firearms confiscated by the Dallas, Texas, police department from 1980 to 1992 as indicators of the types of guns circulating among criminal/high-risk groups, the project examined changes over time in Dallas' street gun arsenal and assessed the impact these changes had upon gun violence mortality in Dallas. The focus of the project was on the characteristics of the guns rather than their numbers. All confiscated firearms were analyzed and characterized according to basic weapon type and caliber groupings. Dates of confiscation were missing from the majority of the pre-1988 records, but by aggregating the gun data into bimonthly (Part 1) and quarterly (Part 2) time series databases, it was possible to estimate the bimonthly and quarterly periods of confiscation for most of the 1980-1992 records. Records that could not be assigned to bimonthly or quarterly periods were dropped. Confiscated firearms were grouped into basic categories based on stopping power (i.e., wounding potential), rate of fire, and ammunition capacity. The following measures were created for each bimonthly and quarterly period: (1) weapons with high stopping power (large guns), (2) semiautomatic weaponry (semis), (3) weapons combining high stopping power and a semiautomatic firing mechanism (large semis), (4) handguns with high stopping power (large handguns), (5) semiautomatic handguns (semi handguns), and (6) handguns combining high stopping power and semiautomatic firing (large semi handguns). Several violence measures were obtained from the Federal Bureau of Investigation's (FBI) Uniform Crime Reports Supplemental Homicide Reports and Return A (or Offenses Known and Clearances by Arrest) data files (see UNIFORM CRIME REPORTING PROGRAM DATA [UNITED STATES]: 1975-1997 [ICPSR 9028]). These measures were also aggregated at bimonthly and quarterly levels. Data from the Dallas Police Department master gun property file include total handguns, total semiautomatic handguns, total large-caliber handguns, total large-caliber semiautomatic handguns, total shotguns, total semiautomatic shotguns, total rifles, total semiautomatic rifles, and total counts and total semiautomatic counts for various calibers of handguns, shotguns, and rifles. Data that were aggregated using the FBI data include total homicides, gun homicides, total robberies, gun robberies, and gun aggravated assaults. The data file also includes the year and the bimonthly or quarterly period counter.

National Firearms Survey, 1999 (ICPSR 4552)

Released/updated on: 2007-07-06
Geographic coverage: United States
Time period: 1999-01-01--1999-12-31
This survey was undertaken to obtain information on the characteristics of gun ownership, gun storage and gun carrying practices, and weapons-related incidents in the United States--specifically, use of guns and other weapons in self-defense against other people. Data were collected using national random-digit dial telephone surveys completed between March 19, 1999 and July 13, 1999. Sampling was suspended after the school shooting in Littleton, Colorado on April 20, 1999, and resumed after a cool-down period. Part 1, Survey Data, contains the coded data obtained during the interviews, and Part 2, Open-Ended Verbatim Responses, consists of open-ended answers provided by the respondents. Four qualifying questions were asked, dealing with: (1) gun ownership, (2) gun display against the respondent, (3) gun use in self-defense against another person, and (4) the use of a weapon other than a gun in self-defense against another person. A "yes" response to a qualifying question led to a series of additional questions on the same topic as the qualifying question. Information was collected from all respondents on the perceived safety of their neighborhood, whether they would feel safer if more people owned guns, whether guns should be allowed in public places, whether gun injuries were a problem in their community, whether they would favor or oppose a program to reduce gun injuries, and whether they had ever been shot with a gun. Respondents living in households that currently contained a gun were asked how many and what type of guns were present, the main reasons for owning a gun, whether any of the guns were loaded and unlocked, and whether they had received formal firearms training. Questions about incidents in which a gun was displayed in a hostile manner against the respondent included the number of times it took place, how long ago it had occurred, whether the respondent was in the military or police force at the time, the location of the incident, whether the individual displaying the gun was known to the respondent, whether the respondent had a gun, and whether the police were contacted. Respondents who had used a gun or other weapon in self-defense in the last five years were asked about the number of times it took place, the location of the incident, whether they were in the military or police force at the time, the type of weapon used, whether they knew the other person, whether this individual also had a weapon, whether the police were contacted and arrests made, and what crime was committed. Additional questions asked respondents whether they smoked cigarettes, drank alcohol, whether they had gotten married, had had a fire in their home, and had been hospitalized for a fracture in the past year, and whether they had ever had contact with extraterrestrial life. Demographic variables include sex, age, race, education level, household income, type of residential area (e.g., urban, rural, etc.), and age and number of children in the household.

Time period: 2000-01-01--2002-12-31
The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One such measure was the Fear and Guns instrument. It was administered to subjects in Cohorts 6, 9, and 12 and obtained information regarding the subject's fear in certain situations and the accessibility and use of guns. This instrument combined elements from PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): WHERE ARE YOU AFRAID? (FEAR), WAVE 2, 1997-2000 (ICPSR 13621) and PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): GUN OWNERSHIP, WAVE 2, 1997-2000 (ICPSR 13626). It is closely related to PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): GUN OWNERSHIP, WAVE 3, 2000-2002 (ICPSR 13711).
