Gang Involvement in "Rock" Cocaine Trafficking in Los Angeles, 1984-1985 (ICPSR 9398)
Released/updated on: 2006-03-30
Geographic coverage: United States, Los Angeles, California
Time period: 1984-01-01--1985-01-01
The purpose of this data collection was to investigate the possible increase in gang involvement within cocaine and "rock" cocaine trafficking. Investigators also examined the relationships among gangs, cocaine trafficking, and increasing levels of violence. They attempted to determine the effects of increased gang involvement in cocaine distribution in terms of the location of an incident, the demographic profiles of suspects, and the level of firearm use. They also looked at issues such as whether the connection between gangs and cocaine trafficking yielded more drug-related violence, how the connection between gangs and cocaine trafficking affected police investigative processes such as intra-organizational communication and the use of special enforcement technologies, what kinds of working relationships were established between narcotics units and gang control units, and what the characteristics were of the rock trafficking and rock house technologies of the dealers. Part 1 (Sales Arrest Incident Data File) contains data for the cocaine sales arrest incidents. Part 2 (Single Incident Participant Data File) contains data for participants of the cocaine sales arrest incidents. Part 3 (Single Incident Participant Prior Arrest Data File) contains data for the prior arrests of the participants in the cocaine arrest incidents. Part 4 (Multiple Event Incident Data File) contains data for multiple event incidents. Part 5 (Multiple Event Arrest Incident Data File) contains data for arrest events in the multiple event incidents. Part 6 (Multiple Event Incident Participant Data File) contains data for the participants of the arrest events. Part 7 (Multiple Event Incident Prior Arrest Data File) contains data for the prior arrest history of the multiple event participants. Part 8 (Homicide Incident Data File) contains data for homicide incidents. Part 9 (Homicide Incident Suspect/Victim Data File) contains data for the suspects and victims of the homicide incidents. Major variables characterizing the various units of observation include evidence of gang involvement, presence of drugs, presence of a rock house, presence of firearms or other weapons, presence of violence, amount of cash taken as evidence, prior arrests, and law enforcement techniques.

Police Response to Street Gang Violence in California: Improving the Investigative Process, 1985 (ICPSR 8934)
Released/updated on: 2006-01-12
Geographic coverage: United States, California
This data collection examines gang and non-gang homicides as well as other types of offenses in small California jurisdictions. Data are provided on violent gang offenses and offenders as well as on a companion sample of non-gang offenses and offenders. Two separate data files are supplied, one for participants and one for incidents. The participant data include age, gender, race, and role of participants. The incident data include information from the "violent incident data collection form" (setting, auto involvement, and amount of property loss), and the "group indicators coding form" (argot, tattoos, clothing, and slang terminology).

Prevalence of Five Gang Structures in 201 Cities in the United States, 1992 and 1995 (ICPSR 2792)
Released/updated on: 2005-11-04
Geographic coverage: United States
The goal of this study was to provide useful data on how street gang crime patterns (by amount and type of offense) relate to common patterns of street gang structure, thus providing focused, data-based guidelines for gang control and intervention. The data collection consists of two components: (1) descriptions of cities' gang activities taken from an earlier study of gang migration in 1992, IMPACT OF GANG MIGRATION: EFFECTIVE RESPONSES BY LAW ENFORCEMENT AGENCIES IN THE UNITED STATES, 1992 (ICPSR 2570), and (2) gang structure data from 1995 interviews with police agencies in a sample of the same cities that responded to the 1992 survey. Information taken from the 1992 study includes the year of gang emergence in the city, numbers of active gangs and gang members, ethnic distribution of gang members, numbers of gang homicides and "drive-bys" in 1991, state in which the city is located, and population of the city. Information from the 1995 gang structures survey provides detail on the ethnic distributions of gangs, whether a predominant gang structure was present, each gang structure's typical size, and the total number of each of the five gang structures identified by the principal investigators -- chronic traditional, emergent traditional, emergent integrated, expanded integrated, and specialty integrated. City crime information was collected on the spread of arrests, number of serious arrests, volume and specialization of crime, arrest profile codes and history, uniform crime rate compared to city population, ratio of serious arrests to total arrests, and ratio of arrests to city population.

Street Gangs and Drug Sales in Pasadena and Pomona, California, 1989-1991 (ICPSR 6255)
Released/updated on: 2006-01-12
Geographic coverage: United States, Pomona, California, Pasadena
Time period: 1989-01-01--1991-01-01
These data were collected to explore connections between street gangs and drug distribution. The research objectives for this study were (1) to assess the magnitude of gang involvement in cocaine and other drug sales in two suburban cities, (2) to compare the characteristics of gang-involved drug sale incidents with those without gang involvement, (3) to assess the generalizability of findings on cocaine to other drugs, and from urban to more suburban settings, and (4) to translate the implications of the research findings into the development of law enforcement strategies. Law enforcement arrest records and gang membership records were obtained for two study sites, Pasadena and Pomona, California. Part 1, the incident-level file, supplies information on arrest incidents qualifying as drug sales. Variables in the file include presence at arrest of violence, guns, cash, and drugs, types of charges, gang characteristics of the incident, racial/ethnic makeup of arrestees, gender of arrestees, and gang affiliation of arrestees. Part 2, the participant-level file, supplies data on each participant in each incident. Variables in this file include gender, ethnicity, gang membership status, and charges.
