This study examined the impact that a six-month broken windows style policing crackdown on disorder had on residents of three California cities: Colton, Ontario and Redlands. The study investigated four questions:
- What is the impact of broken windows policing on fear of crime among residents of the targeted hot spots?
- What is the impact of broken windows policing on police legitimacy in the targeted hot spots?
- What is the impact of broken windows policing on reports of collective efficacy in the targeted hot spots?
- Is broken windows policing at hot spots effective in reducing both actual and perceived levels of disorder and crime in the targeted hot spots?
To answer these questions, a block randomized experimental design was employed to deliver a police intervention targeting disorder to 55 treatment street segments with an equal number of segments serving as controls.
Data were collected on the type and amount of crime before, during, and after implementation as well as interviews of residents before and after the crackdown in order to gauge their perception of its success.

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--1980-10-31
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
Time period: 1979-01-01--1979-12-31
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
Time period: 1979-01-01--1979-12-31
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.

Crime-Induced Business Relocations in the Austin [Texas] Metropolitan Area, 1995-1996 (ICPSR 3078)
Released/updated on: 2006-03-30
Geographic coverage: United States, Texas, Austin
Time period: 1995-01-01--1996-12-31
There were three key objectives to this study: (1) to determine the relative importance of crime-related as well as business-related factors in business relocation decisions, including business ownership, type of business, and business size, (2) to ascertain how businesses respond to crime and fear of crime, such as by moving, adding more security, requesting police protection, or cooperating with other businesses, and (3) to identify the types of crime prevention measures and assistance that businesses currently need and to assess the roles of business associations and police departments in providing enhanced crime prevention assistance. From November 1995 through February 1996 a mail survey was distributed to a sample of three different groups of businesses in Austin's 14 highest crime ZIP codes. The groups consisted of: (1) businesses that remained within the same ZIP code between 1990 and 1993, (2) new firms that either moved into a high-crime ZIP code area between 1990 and 1993 or were created in a high-crime ZIP code between 1990 and 1993, and (3) businesses that relocated from high-crime ZIP code areas to other locations in Austin's metropolitan area or elsewhere in Texas. Variables include type of business, ownership of business, number of employees, reasons for moving or staying in neighborhood, types of crime that affected business, owner's response to business crime, customer safety, and the role of business associations and the police in preventing crime.

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--1975-12-31
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.

Harnessing Existing Technologies to Mitigate Driving Distraction Among Law Enforcement Officers, Iowa, Tennessee, Wisconsin, Wyoming, 2019 (ICPSR 38994)
Released/updated on: 2026-06-29
Geographic coverage: Iowa, United States, Wyoming, Tennessee, Wisconsin
Time period: 2019-01-01--2019-12-31
Nearly half of the law enforcement officers killed in the line of duty in the United States were due to automobile crashes. Driver distraction has been identified as a common causal factor leading to the crash, with the primary source of distractions being the mobile computer. While there is plenty of literature on officer safety, what is lacking is an understanding of the needs of the officers to interact with the control or communication equipment while driving and how that interaction impacts distraction and, consequently, officer safety. To examine these issues, the research team conducted focus group discussions with law enforcement officers from local, county, and state agencies in four states. The two primary topics of discussion were:
- Officer requirements to operate different pieces of equipment while driving, and
- Different software and systems being used in patrol cars.

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--1975-12-31
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.

Police Services Study, Phase II, 1977: Rochester, St. Louis, and St. Petersburg (ICPSR 8605)
Released/updated on: 2006-03-30
Time period: 1977-05-01--1977-08-31
The data for this study were collected in order to examine the delivery of police services in selected neighborhoods. Performances of police agencies organized in different ways were compared as they delivered services to different sets of comparable neighborhoods. For Part 1, Citizen Debriefing Data, data were drawn from telephone interviews conducted with citizens who were involved in police-citizen encounters or who requested police services during the observed shifts. The file contains data on the citizens involved in observed encounters, their satisfaction with the delivered services, and neighborhood characteristics. This file includes variables such as the type of incident, estimated property loss, police response time, type of action taken by police, citizen satisfaction with the handling of the problem by police, reasons for dissatisfaction, the emotional state of the citizen during the encounter, whom the officers referred the citizen to for help, the citizen's prior contacts with police, and the citizen's education, age, sex, and total family income. Part 2, General Shift Information, contains data describing the shift (i.e., the eight-hour tour of duty to which the officers were assigned), the officers, and the events occurring during an observed shift. This file includes such variables as the total number of encounters, a breakdown of dispatched runs by type, the number of contacts with other officers, the number of contacts with non-police support units, officer discretion in taking legal action, and officer attitudes on patrol styles and activities. Part 3, Police Encounters Data, describes police encounters observed by the research team during selected shifts. It consists of information describing the officers' role in encounters with citizens observed during a shift and their demeanor toward the citizens involved. The file includes variables such as the type of encounter, how the encounter began, whether the citizens involved possessed a weapon, the encounter location, what other agencies were present during the encounter and when they arrived, police actions during the encounter, the role of citizens involved in the encounter, the demeanor of the officer toward the citizens during the encounter, actions taken by the citizens, which services were requested by the citizens, and how the observer affected the encounter. Part 4, Victimization Survey Data, examined citizen attitudes about the police and crime in their neighborhoods. The data were obtained through telephone interviews conducted by trained interviewers. These interviews followed a standard questionnaire designed by the project leaders. Variables include perceived risk of victimization, evaluations of the delivery of police services, household victimization occurring in the previous year, actions taken by citizens in response to crime, and demographic characteristics of the neighborhood.

Reexamining the Minneapolis Repeat Complaint Address Policing (RECAP) Experiment, 1986-1987 (ICPSR 6172)
Released/updated on: 2006-01-12
Geographic coverage: Minneapolis, United States, Minnesota
Time period: 1986-01-01--1987-12-31
This study reexamines REPEAT COMPLAINT ADDRESS POLICING: TWO FIELD EXPERIMENTS IN MINNEAPOLIS, 1985-1987 (ICPSR 9788). The original Repeat Complaint Address Policing (RECAP) experiment was a field study of the strategy of problem-oriented policing, which used control and treatment groups consisting of specific addresses in the city of Minneapolis. The impact of problem-oriented policing was measured by comparing the number of 911 calls received for each address during a baseline period to the number received during a period when experimental treatments were in effect. Several features of the original data distort the one-to-one correspondence between a 911 call and an event, such as the occurrence of multiple versions of the same call in the databases. The current study identifies and attempts to correct these occurrences by applying multiple levels of data cleaning procedures to the original data to establish a better one-to-one call-to-event correspondence.

Reporting of Drug-Related Crimes: Resident and Police Perspectives in the United States, 1988-1990 (ICPSR 9925)
Released/updated on: 2005-11-04
Geographic coverage: United States
Time period: 1988-01-01--1990-12-31
This data collection investigates the ways in which police use reports of drug-related crimes provided by residents of high drug/crime areas and how willing residents of these areas are to report such crimes to the police. Structured interviews were conducted by telephone with police representatives in most of the nation's 50 largest cities and in person with residents and police officers in high drug/crime districts in each of four major cities: Newark, Chicago, El Paso, and Philadelphia. Police department representatives were queried about the usefulness of citizen reports, reasons for citizens' reluctance to make reports, how the rate of citizen reports could be improved, and how citizen reports worked with other community crime prevention strategies. Residents were asked about their tenure in the neighborhood, attitudes toward the quality of life in the neighborhood, major social problems facing the neighborhood, and quality of city services such as police and fire protection, garbage collection, and public health services. Additional questions were asked about the amount of crime in the neighborhood, the amount of drug use and drug-related crime, and the fear of crime. Basic demographic information such as sex, race, and language in which the interview was conducted is also provided.
