Characteristics of High and Low Crime Neighborhoods in Atlanta, 1980 (ICPSR 7951)
Released/updated on: 2005-11-04
Geographic coverage: United States, Atlanta, Georgia
Time period: 1980-08-01--1980-10-01
This study examines the question of how some urban neighborhoods maintain a low crime rate despite their proximity and similarity to relatively high crime areas. The purpose of the study is to investigate differences in various dimensions of the concept of territoriality (spatial identity, local ties, social cohesion, informal social control) and physical characteristics (land use, housing, street type, boundary characteristics) in three pairs of neighborhoods in Atlanta, Georgia. The study neighborhoods were selected by locating pairs of adjacent neighborhoods with distinctly different crime levels. The criteria for selection, other than the difference in crime rates and physical adjacency, were comparable racial composition and comparable economic status. This data collection is divided into two files. Part 1, Atlanta Plan File, contains information on every parcel of land within the six neighborhoods in the study. The variables include ownership, type of land use, physical characteristics, characteristics of structures, and assessed value of each parcel of land within the six neighborhoods. This file was used in the data analysis to measure a number of physical characteristics of parcels and blocks in the study neighborhoods, and as the sampling frame for the household survey. The original data were collected by the City of Atlanta Planning Bureau. Part 2, Atlanta Survey File, contains the results of a household survey administered to a stratified random sample of households within each of the study neighborhoods. Variables cover respondents' attitudes and behavior related to the neighborhood, fear of crime, avoidance and protective measures, and victimization experiences. Crime rates, land use, and housing characteristics of the block in which the respondent resided were coded onto each case record.

Citizen Participation and Community Crime Prevention, 1979: Chicago Metropolitan Area Survey (ICPSR 8086)
Released/updated on: 2005-11-04
This survey was conducted as part of the Citizen Participation and Community Crime Prevention project at the Center for Urban Affairs and Policy Research, Northwestern University. The project was conducted to gain a deeper understanding of the wide range of activities in which the American public engages to be secure from crime. In particular, this survey was designed to identify the scope of anti-crime activities and investigate the processes that facilitate or inhibit the public's involvement in those activities. The geographical area for the survey was defined by the "commuting basin" of Chicago, excluding several independent cities and their suburbs (e.g., Aurora, Waukegan, and Joliet) on the northern and western fringes of that area, and excluding all areas in Indiana. Interviewing was carried out by the Survey Research Laboratory at the University of Illinois during June through August 1979. Information was gathered on people's opinions toward safety, their involvement with crime prevention activities, and the quality of life in their neighborhoods. In addition, data were assembled from Census Bureau and police reports for each community area in which respondents lived in the years immediately preceding the survey.

Crime Factors and Neighborhood Decline in Chicago, 1979 (ICPSR 7952)
Released/updated on: 1997-09-26
Geographic coverage: United States, Chicago, Illinois
This study explores the relationship between crime and neighborhood deterioration in eight neighborhoods in Chicago. The neighborhoods were selected on the basis of slowly or rapidly appreciating real estate values, stable or changing racial composition, and high or low crime rates. These data provide the results of a telephone survey administered to approximately 400 heads of households in each study neighborhood, a total of 3,310 completed interviews. The survey was designed to measure victimization experience, fear and perceptions of crime, protective measures taken, attitudes toward neighborhood quality and resources, attitudes toward the neighborhood as an investment, and density of community involvement. Each record includes appearance ratings for the block of the respondent's residence and aggregate figures on personal and property victimization for that city block. The aggregate appearance ratings were compiled from windshield surveys taken by trained personnel of the National Opinion Research Center. The criminal victimization figures came from Chicago City Police files.

Decision-Related Research on the Organization of Service Delivery Systems in Metropolitan Areas: Police Protection (ICPSR 7427)
Released/updated on: 2006-03-30
Geographic coverage: United States
Time period: 1970-01-01--1975-01-01
This study represents one of four research projects on service delivery systems in metropolitan areas, covering fire protection (DECISION-RELATED RESEARCH ON THE ORGANIZATION OF SERVICE DELIVERY SYSTEMS IN METROPOLITAN AREAS: FIRE PROTECTION [ICPSR 7409]), public health (DECISION-RELATED RESEARCH ON THE ORGANIZATION OF SERVICE DELIVERY SYSTEMS IN METROPOLITAN AREAS: PUBLIC HEALTH [ICPSR 7374]), solid waste management (DECISION-RELATED RESEARCH ON THE ORGANIZATION OF SERVICE DELIVERY SYSTEMS IN METROPOLITAN AREAS: SOLID WASTE MANAGEMENT [ICPSR 7487]), and police protection (the present study). All four projects used a common unit of analysis, namely all 200 Standard Metropolitan Statistical Areas (SMSAs) that, according to the 1970 Census, had a population of less than 1,500,000 and were entirely located within a single state. In each project, a limited amount of information was collected for all 200 SMSAs. More extensive data were gathered within independently drawn samples of these SMSAs, for all local geographical units and each administrative jurisdiction or agency in the service delivery areas. Two standardized systems of geocoding -- the Federal Information Processing Standard (FIPS) codes and the Office of Revenue Sharing (ORS) codes -- were used, so that data from various sources could be combined. The use of these two coding schemes also allows users to combine data from two or more of the research projects conducted in conjunction with the present one, or to add data from a wide variety of public data files. The present study used five major clusters of variables to investigate the delivery of police services: service conditions, the legal structure, organizational arrangements, manpower levels, and expenditure levels. Information about specific services such as patrol, traffic control, criminal investigation, radio communications, adult pre-trial detention, entry-level training, and crime laboratory analysis was collected at the local jurisdiction level in a random sample of 80 SMSAs. Part 1 summarizes in matrix form the relationships between all consumers and producers for each type of service in a given SMSA. Part 2 provides data about 1,885 consuming units, or service areas, defined as mutually exclusive geographical divisions of each SMSA that received police services. Part 3 contains information for 1,761 police agencies, defined as service producers, with functions and duties that may overlap several jurisdictions.

Geographic coverage: District of Columbia, United States, Phoenix, Los Angeles, California, Arizona
Time period: 1986-01-01--1989-01-01
This study investigates rates of serious crime for selected public housing developments in Washington, DC, Phoenix, Arizona, and Los Angeles, California, for the years 1986 to 1989. Offense rates in housing developments were compared to rates in nearby areas of private housing as well as to city-wide rates. In addition, the extent of law enforcement activity in housing developments as represented by arrests was considered and compared to arrest levels in other areas. This process allowed both intra-city and inter-city comparisons to be made. Variables cover study site, origin of data, year of event, offense codes, and location of event. Los Angeles files also include police division.

Effects of Local Sanctions on Serious Criminal Offending in Cities with Populations Over 100,000, 1978-1983: [United States] (ICPSR 9590)
Released/updated on: 1998-02-23
Geographic coverage: United States
Time period: 1978-01-01--1983-01-01
These data assess the effects of the risk of local jail incarceration and of police aggressiveness in patrol style on rates of violent offending. The collection includes arrest rates for public order offenses, size of county jail populations, and numbers of new prison admissions as they relate to arrest rates for index (serious) crimes. Data were collected from seven sources for each city. CENSUS OF POPULATION AND HOUSING, 1980 [UNITED STATES]: SUMMARY TAPE FILE 1A (ICPSR 7941), provided county-level data on number of persons by race, age, and age by race, number of persons in households, and types of households within each county. CENSUS OF POPULATION AND HOUSING, 1980 [UNITED STATES]: SUMMARY TAPE FILE 3A (ICPSR 8071), measured at the city level, provided data on total population, race, age, marital status by sex, persons in household, number of households, housing, children, and families above and below the poverty level by race, employment by race, and income by race within each city. The Federal Bureau of Investigation (FBI) 1980 data provided variables on total offenses and offense rates per 100,000 persons for homicides, rapes, robbery, aggravated assault, burglary, larceny, motor vehicle offenses, and arson. Data from the FBI for 1980-1982, averaged per 100,000, provided variables for the above offenses by sex, age, and race, and the Uniform Crime Report arrest rates for index crimes within each city. The NATIONAL JAIL CENSUS for 1978 and 1983 (ICPSR 7737 and ICPSR 8203), aggregated to the county level, provided variables on jail capacity, number of inmates being held by sex, race, and status of inmate's case (awaiting trial, awaiting sentence, serving sentence, and technical violations), average daily jail populations, number of staff by full-time and part-time, number of volunteers, and number of correctional officers. The JUVENILE DETENTION AND CORRECTIONAL FACILITY CENSUS for 1979 and 1982-1983 (ICPSR 7846 and 8205), aggregated to the county level, provided data on the number of individuals being held by type of crime and sex, as well as age of juvenile offenders by sex, average daily prison population, and payroll and other expenditures for the institutions.

Evaluation of the Children at Risk Program in Austin, Texas, Bridgeport, Connecticut, Memphis, Tennessee, Savannah, Georgia, and Seattle, Washington, 1993-1997 (ICPSR 2686)
Released/updated on: 2006-03-30
Geographic coverage: Bridgeport, Seattle, Savannah, United States, Texas, Tennessee, Connecticut, Memphis, Georgia, Austin, Washington
Time period: 1993-01-01--1997-01-01
The Children at Risk (CAR) Program was a comprehensive, neighborhood-based strategy for preventing drug use, delinquency, and other problem behaviors among high-risk youth living in severely distressed neighborhoods. The goal of this research project was to evaluate the long-term impact of the CAR program using experimental and quasi-experimental group comparisons. Experimental comparisons of the treatment and control groups selected within target neighborhoods examined the impact of CAR services on individual youths and their families. These services included intensive case management, family services, mentoring, and incentives. Quasi-experimental comparisons were needed in each city because control group youths in the CAR sites were exposed to the effects of neighborhood interventions, such as enhanced community policing and enforcement activities and some expanded court services, and may have taken part in some of the recreational activities after school. CAR programs in five cities -- Austin, TX, Bridgeport, CT, Memphis, TN, Seattle, WA, and Savannah, GA -- took part in this evaluation. In the CAR target areas, juveniles were identified by case managers who contacted schools and the courts to identify youths known to be at risk. Random assignment to the treatment or control group was made at the level of the family so that siblings would be assigned to the same group. A quasi-experimental group of juveniles who met the CAR eligibility risk requirements, but lived in other severely distressed neighborhoods, was selected during the second year of the evaluation in cities that continued intake of new CAR participants into the second year. In these comparison neighborhoods, youths eligible for the quasi-experimental sample were identified either by CAR staff, cooperating agencies, or the staff of the middle schools they attended. Baseline interviews with youths and caretakers were conducted between January 1993 and May 1994, during the month following recruitment. The end-of-program interviews were conducted approximately two years later, between December 1994 and May 1996. The follow-up interviews with youths were conducted one year after the program period ended, between December 1995 and May 1997. Once each year, records were collected from the police, courts, and schools. Part 1 provides demographic data on each youth, including age at intake, gender, ethnicity, relationship of caretaker to youth, and youth's risk factors for poor school performance, poor school behavior, family problems, or personal problems. Additional variables provide information on household size, including number and type of children in the household, and number and type of adults in the household. Part 2 provides data from all three youth interviews (baseline, end-of-program, and follow-up). Questions were asked about the youth's attitudes toward school and amount of homework, participation in various activities (school activities, team sports, clubs or groups, other organized activities, religious services, odd jobs or household chores), curfews and bedtimes, who assisted the youth with various tasks, attitudes about the future, seriousness of various problems the youth might have had over the past year and who he or she turned to for help, number of times the youth's household had moved, how long the youth had lived with the caretaker, various criminal activities in the neighborhood and the youth's concerns about victimization, opinions on various statements about the police, occasions of skipping school and why, if the youth thought he or she would be promoted to the next grade, would graduate from high school, or would go to college, knowledge of children engaging in various problem activities and if the youth was pressured to join them, and experiences with and attitudes toward consumption of cigarettes, alcohol, and various drugs. Three sections of the questionnaire were completed by the youths. Section A asked questions about the youth's attitudes toward various statements about self, life, the home environment, rules, and norms. Section B asked questions about the number of times that various crimes had been committed against the youth, his or her sexual activity, number of times the youth ran away from home, number of times he or she had committed various criminal acts, and what weapons he or she had carried. Items in Section C covered the youth's alcohol and drug use, and participation in drug sales. Part 3 provides data from both caretaker interviews (baseline and end-of-program). Questions elicited the caretaker's assessments of the presence of various positive and negative neighborhood characteristics, safety of the child in the neighborhood, attitudes toward and interactions with the police, if the caretaker had been arrested, had been on probation, or in jail, whether various crimes had been committed against the caretaker or others in the household in the past year, activities that the youth currently participated in, curfews set by the caretaker, if the caretaker had visited the school for various reasons, school performance or problems by the youth and the youth's siblings, amount of the caretaker's involvement with activities, clubs, and groups, the caretaker's financial, medical, and personal problems and assistance received in the past year, if he or she was not able to obtain help, why not, and information on the caretaker's education, employment, income level, income sources, and where he or she sought medical treatment for themselves or for the youth. Two sections of the data collection instruments were completed by the caretaker. Section A dealt with the youth's personal problems or problems with others, and the youth's friends. Additional questions focused on the family's interactions, rules, and norms. Section B items asked about the caretaker's alcohol and drug use, and any alcohol and drug use or criminal justice involvement by others in the household older than the youth. Part 4 consists of data from schools, police, and courts. School data include the youth's grades, grade-point average (GPA), absentee rate, reasons for absences, and whether the youth was promoted each school year. Data from police records include police contacts, detentions, violent offenses, drug-related offenses, and arrests prior to recruitment in the CAR program and in Years 1-4 after recruitment, court contacts and charges prior to recruitment and in Years 1-4 after recruitment, and how the charges were disposed.

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.

Immigrant Populations as Victims in New York City and Philadelphia, 1994 (ICPSR 6793)
Released/updated on: 2005-11-04
Geographic coverage: New York City, United States, New York (state), Philadelphia, Pennsylvania
The purpose of this study was to examine interrelated issues surrounding the use of the criminal justice system by immigrant victims and to identify ways to improve the criminal justice response to immigrants' needs and problems. Two cities, New York City and Philadelphia, were selected for intensive investigation of victimization of immigrants. In each of these cities, three immigrant communities in a neighborhood were chosen for participation. In New York's Jackson Heights area, Colombians, Dominicans, and Indians were the ethnic groups studied. In Philadelphia's Logan section, Vietnamese, Cambodians, and Koreans were surveyed. In all, 87 Jackson Heights victims were interviewed and 26 Philadelphia victims were interviewed. The victim survey questions addressed can be broadly divided into two categories: issues pertaining to crime reporting and involvement with the court system by immigrant victims. Variables include type of crime, respondent's role in the incident, relationship to the perpetrator, whether the incident was reported to police, and who reported the incident. Respondents were also asked whether they were asked to go to court, whether they understood what the people in court said to them, whether they understood what was happening in their case, and, if victimized again, whether they would report the incident to the police.

Impact of Gang Migration: Effective Responses by Law Enforcement Agencies in the United States, 1992 (ICPSR 2570)
Released/updated on: 2006-03-30
Geographic coverage: United States
This study was the first attempt to investigate gang migration systematically and on a national level. The primary objectives of the study were (1) to identify the scope of gang migration nationally, (2) to describe the nature of gang migration, (3) to assess the impact of gang migration on destination cities, and (4) to describe the current law enforcement responses to the migration of gangs and identify those that appeared to be most effective for various types of migration. Two phases of data collection were used. The major objective of the initial phase was to identify cities that had experienced gang migration (Part 1). This was accomplished by distributing a brief mail questionnaire in 1992 to law enforcement agencies in cities identified as potential gang or gang migration sites. The second major phase of data collection involved in-depth telephone interviews with law enforcement officers in cities that had experienced gang migration in order to develop descriptions of the nature of migration and police responses to it (Part 2). For Part 1, information was collected on the year migration started, number of migrants in the past year, factors that deter gang migration, number of gang members, names of gangs, ethnic distribution of gang members and their drug market involvement, number of gang homicides, number of 1991 gang "drive-bys", and if gangs or narcotics were specified in the respondent's assignment. For Part 2, information was collected on the demographics of gang members, the ethnic percentage of drug gang members and their involvement in distributing specific drugs, and the influence of gang migrants on local gang and crime situations in terms of types and methods of crime, drug distribution activities, technology/equipment used, and targets of crime. Information on patterns of gang migration, including motivations to migrate, drug gang migration, and volume of migration, was also collected. Local responses to gang migration covered information sources, department policies relative to migration, gang specialization in department, approaches taken by the department, and information exchanges and coordination among local, state, and federal agencies.

Interaction Between Neighborhood Change and Criminal Activity, 1950-1976: Los Angeles County (ICPSR 9056)
Released/updated on: 1998-05-27
Geographic coverage: United States, Los Angeles, California
This study was conducted in 1979 at the Social Science Research Institute, University of Southern California, and explores the relationship between neighborhood change and crime rates between the years 1950 and 1976. The data were aggregated by unique and consistently-defined spatial areas, referred to as dummy tracts or neighborhoods, within Los Angeles County. By combining United States Census data and administrative data from several state, county, and local agencies, the researchers were able to develop measures that tapped the changing structural and compositional aspects of each neighborhood and their interaction with the patterns of juvenile delinquency. Some of the variables included are annual income, home environment, number of crimes against persons, and number of property crimes.

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.

National Crime Surveys: Cities Attitude Sub-Sample, 1972-1975 (ICPSR 7663)
Released/updated on: 2006-01-12
Geographic coverage: United States
Time period: 1972-01-01--1975-01-01
This subsample of the national crime surveys consists of data on personal and household victimization for persons aged 12 and older in 26 major United States cities in the period 1972-1975. The National Crime Surveys were designed by the Bureau of Justice Statistics to meet three primary objectives: (1) to develop detailed information about the victims and consequences of crime, (2) to estimate the numbers and types of crimes not reported to police, and (3) to provide uniform measures of selected types of crimes in order to permit reliable comparisons over time and between areas. The surveys provide measures of victimization on the basis of six crimes (including attempts): rape, robbery, assault, burglary, larceny, and motor vehicle theft. The total National Crime Survey employed two distinct samples: a National Sample, and a Cities Sample. The cities sample consists of information about victimization in 26 major United States cities. The data collection was conducted by the United States Census Bureau, initial processing of the data and documentation was performed by the Data Use and Access Laboratories (DUALabs), and subsequent processing was performed by the ICPSR under grants from the Bureau of Justice Statistics (BJS). This Cities Attitude Sub-Sample study also includes information on personal attitudes and perceptions of crime and the police, the fear of crime, and the effect of this fear on behavioral patterns such as choice of shopping areas and places of entertainment. Data are provided on reasons for respondents' choice of neighborhood, and feelings about neighborhood, crime, personal safety, and the local police. Also specified are date, type, place, and nature of the incidents, injuries suffered, hospital treatment and medical expenses incurred, offender's personal profile, relationship of offender to victim, property stolen and value, items recovered and value, insurance coverage, and police report and reasons if incident was not reported to the police. Demographic items cover age, sex, marital status, race, ethnicity, education, employment, family income, and previous residence and reasons for migrating. This subsample is a one-half random sample of the Complete Sample, NATIONAL CRIME SURVEYS: CITIES, 1972-1975 (ICPSR 7658), in which an attitude questionnaire was administered. The subsample contains data from the same 26 cities that were used in the Complete Sample.

Pretrial Release Data, 1969 (ICPSR 7538)
Released/updated on: 1992-02-16
This data collection contains information gathered about pretrial release policies, procedures, and outcomes in a 1969 survey of police chiefs, judges, prosecutors, defense attorneys, and bail project directors in 72 cities across the United States (with a higher proportion in Illinois). The research objectives included: (1) developing a model designed to determine the optimum percentage of defendants to hold prior to trial, (2) developing a model designed to make decisions on whether a defendant should be released or held in jail prior to trial, (3) comparing cities having bail reform projects with cities not having them, (4) comparing cities that required arrested persons to provide 10 percent of the bond with cities requiring 100 percent of the bond, and (5) determining the causes and effects of variations across cities in the percentage of defendants held in jail prior to trial. The survey focused on the processing of arrested persons prior to trial. Respondents answered questions about the organization and procedures in pretrial release, supplied approximate statistical data (e.g., percent of arraigned individuals who were released prior to their trial and failed to appear in court for their trial), estimated statistical trends in pretrial release during the previous five years, reported on attitudes in their communities toward administration of bail, rated the importance of several criteria when determining if a defendant was to be allowed pretrial release, and indicated whether their city had a bail reform program, and if so, its characteristics. Demographic data (ranging from population to income to crime rates) about the 72 cities represented in the survey are also included in the file.

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.

Reactions to Crime Project, 1977 [Chicago, Philadelphia, San Francisco]: Survey on Fear of Crime and Citizen Behavior (ICPSR 8162)
Released/updated on: 2005-11-04
Geographic coverage: United States, Chicago, Illinois, Los Angeles, California, Philadelphia, Pennsylvania
Time period: 1977-10-01--1977-12-01
This survey was conducted by the Center for Urban Affairs and Policy Research at Northwestern University to gather information for two projects that analyzed the impact of crime on the lives of city dwellers. These projects were the Reactions to Crime (RTC) Project, which was supported by the United States Department of Justice's National Institute of Justice as part of its Research Agreements Program, and the Rape Project, supported by the National Center for the Prevention and Control of Rape, a subdivision of the National Institute of Mental Health. Both investigations were concerned with individual behavior and collective reactions to crime. The Rape Project was specifically concerned with sexual assault and its consequences for the lives of women. The three cities selected for study were Chicago, Philadelphia, and San Francisco. A total of ten neighborhoods were chosen from these cities along a number of dimensions -- ethnicity, class, crime, and levels of organizational activity. In addition, a small city-wide sample was drawn from each city. Reactions to crime topics covered how individuals band together to deal with crime problems, individual responses to crime such as property marking or the installation of locks and bars, and the impact of fear of crime on day-to-day behavior -- for example, shopping and recreational patterns. Respondents were asked several questions that called for self-reports of behavior, including events and conditions in their home areas, their relationship to their neighbors, who they knew and visited around their homes, and what they watched on TV and read in the newspapers. Also included were a number of questions measuring respondents' perceptions of the extent of crime in their communities, whether they knew someone who had been a victim, and what they had done to reduce their own chances of being victimized. Questions on sexual assault/rape included whether the respondent thought this was a neighborhood problem, if the number of rapes in the neighborhood were increasing or decreasing, how many women they thought had been sexually assaulted or raped in the neighborhood in the previous year, and how they felt about various rape prevention measures, such as increasing home security, women not going out alone at night, women dressing more modestly, learning self-defense techniques, carrying weapons, increasing men's respect of women, and newspapers publishing the names of known rapists. Female respondents were asked whether they thought it likely that they would be sexually assaulted in the next year, how much they feared sexual assault when going out alone after dark in the neighborhood, whether they knew a sexual assault victim, whether they had reported any sexual assaults to police, and where and when sexual assaults took place that they were aware of. Demographic information collected on respondents includes age, race, ethnicity, education, occupation, income, and whether the respondent owned or rented their home.

Survey on Street Disorder in Large Municipalities in the United States, 1994-1996 (ICPSR 2479)
Released/updated on: 2005-11-04
Geographic coverage: United States
Time period: 1994-01-01--1996-01-01
The objective of this survey was to provide city officials and police with information on how to carry out street disorder enforcement strategies within the constitutional guidelines established by the courts. To that end, a survey of 512 municipal police departments was conducted in the spring of 1996. The agencies were asked to supply data for the current year as well as for 1994 and 1995. Information was collected on the existence of particular street disorder ordinances, when such ordinances were passed, the number of citations and arrests resulting from each ordinance, and whether the ordinances were challenged in court. Data covered the following types of street disorder: panhandling, open containers of alcohol, public intoxication, disorderly conduct, sleeping in public places, unregulated day labor solicitation, vending, dumpster diving, camping in public, and juvenile curfews. Departments were also asked about their written policies regarding certain types of street disorder. Other departmental information includes location, number of personnel, and population of jurisdiction.
