Extended National Assessment Survey of Law Enforcement Anti-Gang Information Resources, 1993-1994 (ICPSR 6565)
Released/updated on: 2005-11-04
Geographic coverage: United States
Time period: 1993-01-01--1994-01-01
This survey extended a 1992 survey (NATIONAL ASSESSMENT SURVEY OF LAW ENFORCEMENT ANTI-GANG INFORMATION RESOURCES, 1990-1992 [ICPSR 6237]) in two ways: (1) by updating the information on the 122 municipalities included in the 1992 survey, and (2) by including data on all cities in the United States ranging in population from 150,000 to 200,000 and including a random sample of 284 municipalities ranging in population from 25,000 to 150,000. Gang crime problems were defined in the same manner as in the 1992 survey, i.e., a gang (1) was identified by the police as a "gang," (2) participated in criminal activity, and (3) involved youth in its membership. As in the 1992 survey, a letter was sent to the senior law enforcement departmental administrator of each agency describing the nature of the survey. For jurisdictions included in the 1992 survey, the letter listed the specific information that had been provided in the 1992 survey and identified the departmental representative who provided the 1992 data. The senior law enforcement administrator was asked to report whether a gang crime problem existed within the jurisdiction in 1994. If a problem was reported, the administrator was asked to identify a representative of the department to provide gang crime statistics and a representative who was most knowledgeable on anti-gang field operations. Annual statistics on gang-related crime were then solicited from the departmental statistical representative. Variables include city, state, ZIP code, and population category of the police department, and whether the department reported a gang problem in 1994. Data on the number of gangs, gang members, and gang-related incidents reported by the police department are also provided. If actual numbers were not provided by the police department, estimates of the number of gangs, gang members, and gang-related incidents were calculated by sampling category.

National Assessment Survey of Law Enforcement Anti-Gang Information Resources, 1990-1991 (ICPSR 6237)
Released/updated on: 2005-11-04
Geographic coverage: United States
Time period: 1990-01-01--1991-01-01
This study constituted a systematic national assessment of local law enforcement perceptions of the distribution of gang and gang-like problems in large cities in the United States, law enforcement reactions to gangs, and their policies toward gang problems. One purpose of the study was to examine changes in law enforcement perceptions of the U.S. gang problem that have occurred since NATIONAL YOUTH GANG INTERVENTION AND SUPPRESSION SURVEY, 1980-1987 (ICPSR 9792) was undertaken. The overall goal was to obtain as "conservative" as possible an estimate of the magnitude of the gang problem in the United States as reflected by the official reaction, record-keeping, and reporting of local law enforcement agencies. The agencies were asked to refer the interviewer to the individual representative of the agency who could provide the most information about the agency's processing of information on gangs and other youth-based groups engaged in criminal activity. To obtain each law enforcement agency's official, not personal, perspective on gang problems, anonymity was intentionally avoided. Each respondent was first asked whether the respondent's agency officially identified a "gang problem" within their jurisdiction. Gangs were defined for this study as groups involving youths engaging in criminal activity. Respondents were then asked if their department officially recognized the presence of other kinds of organized groups that engaged in criminal activity and involved youths and that might be identified by their department as crews, posses, or some other designation. Based on affirmative answers to questions on the officially recognized presence of gangs and the kinds of record-keeping employed by their departments, agencies were sent customized questionnaire packets asking for specifics on only those aspects of the gang problem that their representative had reported the agency kept information on. Variables include city name, state, ZIP code, whether the city participated in National Youth Gang Intervention and Suppression Survey, 1980-1987, and, if so, if the city reported a gang problem. Data on gangs include the number of homicides and other violent, property, drug-related, and vice offenses attributed to youth gangs and female gangs, total number of gang incidents, gangs, gang members, female gang members, and gangs comprised only of females for 1991, number of juvenile gang-related incidents and adult gang-related incidents in 1991, number of drive-by shootings involving gang members or female gang members in 1991, and numbers or percent estimates of gang members by ethnic groups for 1990 and 1991. Respondents also indicated whether various strategies for combating gang problems had been attempted by the department, and if so, how effective each of the crime prevention measures were.
