Adjusting the National Crime Victimization Survey's Estimates of Rape and Domestic Violence for Gag Factors, 1986-1990 (ICPSR 6558)

Released/updated on: 1996-10-01
Geographic coverage: United States
Time period: 1986-01-01--1990-01-01
The purpose of this project was to use statistical modeling techniques to estimate rape and domestic assault rates, adjusting for interviewing conditions under which the National Crime Victimization Survey (NCVS) was administered. Data for women 16 years of age and older interviewed in the NCVS (see NATIONAL CRIME SURVEYS: NATIONAL SAMPLE, 1986-1990 [NEAR-TERM DATA] [ICPSR 8864]) were analyzed. The researchers considered whether the type of interview (personal or telephone) and the presence of another person (particularly a spouse) influenced or "gagged" the reporting of rape and domestic violence in the NCVS. The researchers also investigated correlates, primarily demographic in nature, of reporting rape, domestic violence, other assaults, and breaking and entry. In total, the data file contains reports of 434 rapes, 1,973 incidents of domestic violence, 13,459 other assaults, and 88,950 incidents of breaking and entry. The binary-coded variables provide information on whether the respondent was alone during the interview, others who were present, whether the interview was by telephone, whether the respondent refused a telephone interview, the number of persons who lived in the household, whether the respondent owned her home, whether the land use was urban, whether the household the respondent was living in was the same household from the last interview, whether the respondent had moved more than three times in the last five years, and whether an assault, domestic violence incident, rape, breaking and entry, or no crime was reported. Demographic information includes the respondent's education, income, employment during the last six months, marital status at the time of the interview, and whether the respondent was white (or non-white) or Hispanic (or non-Hispanic). Variables coded the same as the NCVS variables include age, respondent's relationship to the offender, type of crime, year and quarter of interview, NCVS control number, and person weight.

Adult Criminal Careers, Michigan: 1974-1977 (ICPSR 8279)

Released/updated on: 1995-03-31
Geographic coverage: United States, Michigan
Time period: 1974-01-01--1977-01-01
These data, taken from the computerized criminal history files of the Federal Bureau of Investigation, were collected to develop estimates of the extent and variation of individual offending. Included are the adult criminal records of individuals 17 years of age and older arrested in Michigan from 1974 to 1977. The primary criterion for inclusion in the sample was at least one arrest in Michigan for murder, rape, robbery, aggravated assault, burglary, or auto theft. Once sampled, the arrest history includes data on all recorded arrests through 1977, regardless of offense type. The full dataset includes records for 41,191 individuals for a total of 200,007 arrests. The dataset is organized by individual and includes demographic characteristics of the individual (birth date, state of birth, sex, and race) followed by information from the individual's arrest record in chronological order. The arrest records include the date of arrest, the offenses charged, the disposition (convicted, dismissed, or acquitted), and the sentence. Because the data are organized by individual, they are suitable for longitudinal analyses of individual offending patterns over time.

Age-by-Race Specific Crime Rates, 1965-1985: [United States] (ICPSR 9589)

Released/updated on: 2005-11-04
Geographic coverage: United States
Time period: 1965-01-01--1985-01-01
These data examine the effects on total crime rates of changes in the demographic composition of the population and changes in criminality of specific age and race groups. The collection contains estimates from national data of annual age-by-race specific arrest rates and crime rates for murder, robbery, and burglary over the 21-year period 1965-1985. The data address the following questions: (1) Are the crime rates reported by the Uniform Crime Reports (UCR) data series valid indicators of national crime trends? (2) How much of the change between 1965 and 1985 in total crime rates for murder, robbery, and burglary is attributable to changes in the age and race composition of the population, and how much is accounted for by changes in crime rates within age-by-race specific subgroups? (3) What are the effects of age and race on subgroup crime rates for murder, robbery, and burglary? (4) What is the effect of time period on subgroup crime rates for murder, robbery, and burglary? (5) What is the effect of birth cohort, particularly the effect of the very large (baby-boom) cohorts following World War II, on subgroup crime rates for murder, robbery, and burglary? (6) What is the effect of interactions among age, race, time period, and cohort on subgroup crime rates for murder, robbery, and burglary? (7) How do patterns of age-by-race specific crime rates for murder, robbery, and burglary compare for different demographic subgroups? The variables in this study fall into four categories. The first category includes variables that define the race-age cohort of the unit of observation. The values of these variables are directly available from UCR and include year of observation (from 1965-1985), age group, and race. The second category of variables were computed using UCR data pertaining to the first category of variables. These are period, birth cohort of age group in each year, and average cohort size for each single age within each single group. The third category includes variables that describe the annual age-by-race specific arrest rates for the different crime types. These variables were estimated for race, age, group, crime type, and year using data directly available from UCR and population estimates from Census publications. The fourth category includes variables similar to the third group. Data for estimating these variables were derived from available UCR data on the total number of offenses known to the police and total arrests in combination with the age-by-race specific arrest rates for the different crime types.

The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.

The study integrated neighborhood-level data on robbery and burglary gathered from local police agencies across the United States, foreclosure data from RealtyTrac (a real estate information company), and a wide variety of social, economic, and demographic control variables from multiple sources. Using census tracts to approximate neighborhoods, the study regressed 2009 neighborhood robbery and burglary rates on foreclosure rates measured for 2007-2008 (a period during which foreclosure spiked dramatically in the nation), while accounting for 2007 robbery and burglary rates and other control variables that captured differences in social, economic, and demographic context across American neighborhoods and cities for this period. The analysis was based on more than 7,200 census tracts in over 60 large cities spread across 29 states. Core research questions were addressed with a series of multivariate multilevel and single-level regression models that accounted for the skewed nature of neighborhood crime patterns and the well-documented spatial dependence of crime.

The study contains one data file with 8,198 cases and 99 variables.

Calls for Service to Police as a Means of Evaluating Crime Trends in Oklahoma City, 1986-1988 (ICPSR 9669)

Released/updated on: 2006-01-12
Geographic coverage: Oklahoma City, United States, Oklahoma
Time period: 1986-06-01--1988-06-01
In an effort to measure the effectiveness of crime deterrents and to estimate crime rates, calls for assistance placed to police in Oklahoma City over a two-year period were enumerated. This type of call was studied in order to circumvent problems such as "interviewer's effect" and sampling errors that occur with other methods. The telephone calls were stratified by police district, allowing for analysis on the neighborhood level to determine whether deterrence operates ecologically--that is, by neighbors informing one another about arrests which took place as a result of their calls to the police. In measuring deterrence, only the calls that concerned robbery were used. To estimate crime rates, calls were tallied on a monthly basis for 18 types of offenses: aggravated assault, robbery, rape, burglary, grand larceny, motor vehicle theft, simple assault, fraud, child molestation, other sex offenses, domestic disturbance, disorderly conduct, public drunkenness, vice and drugs, petty larceny, shoplifting, kidnapping/hostage taking, and suspicious activity.

Convenience Store Crime in Georgia, Massachusetts, Maryland, Michigan, and South Carolina, 1991-1995 (ICPSR 2699)

Released/updated on: 2006-03-30
Geographic coverage: United States, Massachusetts, Georgia, Maryland, South Carolina, Michigan
Time period: 1991-01-01--1995-01-01
For this study, convenience store robbery victims and offenders in five states (Georgia, Massachusetts, Maryland, Michigan, and South Carolina) were interviewed. Robbery victims were identified by canvassing convenience stores in high-crime areas, while a sample of unrelated offenders was obtained from state prison rolls. The aims of the survey were to address questions of injury, to examine store characteristics that might influence the rate of robbery and injury, to compare how both victims and offenders perceived the robbery event (including their assessment of what could be done to prevent convenience store robberies in the future), and to identify ways in which the number of convenience store robberies might be reduced. Variables unique to Part 1, the Victim Data file, provide information on how the victim was injured, whether hospitalization was required for the injury, if the victim used any type of self-protection, and whether the victim had been trained to handle a robbery. Part 2, the Offender Data file, presents variables describing offenders' history of prior convenience store robberies, whether there had been an accomplice, motive for robbing the store, and whether various factors mattered in choosing the store to rob (e.g., cashier location, exit locations, lighting conditions, parking lot size, the number of clerks working, weather conditions, the time of day, and the number of customers in the store). Found in both files are variables detailing whether a victim injury occurred, use of a weapon, how each participant behaved, perceptions of why the store was targeted, what could have been done to prevent the robbery, and ratings by the researchers on the completeness, honesty, and cooperativeness of each participant during the interview. Demographic variables found in both the victim and offender files include age, gender, race, and ethnicity.

Time period: 1970-01-01--2004-01-01
This study focused on the effect of economic resources and racial/ethnic composition on the change in crime rates from 1970-2004 in United States cities in metropolitan areas that experienced a large growth in population after World War II. A total of 352 cities in the following United States metropolitan areas were selected for this study: Atlanta, Dallas, Denver, Houston, Las Vegas, Miami, Orange County, Orlando, Phoenix, Riverside, San Bernardino, San Diego, Silicon Valley (Santa Clara), and Tampa/St. Petersburg. Selection was based on the fact that these areas developed during a similar time period and followed comparable development trajectories. In particular, these 14 areas, known as the "boomburbs" for their dramatic, post-World War II population growth, all faced issues relating to the rapid growth of tract-style housing and the subsequent development of low density, urban sprawls. The study combined place-level data obtained from the United States Census with crime data from the Uniform Crime Reports for five categories of Type I crimes: aggravated assaults, robberies, murders, burglaries, and motor vehicle thefts. The dataset contains a total of 247 variables pertaining to crime, economic resources, and race/ethnic composition.

The study constructed a comprehensive, longitudinal dataset of all counties nested within U.S. States from 1970 to 2012. The study's main purpose was to facilitate research that would further understanding on firearm legislation and its impacts on violence. This comprehensive data collection effort included information on firearm legislation implemented across U.S. States over time in combination with multiple measures of firearm-related violence and injury. Moreover, to better understand the conditions under which firearm legislation is more or less effective, incorporation of county characteristics allowed for examination of whether the effectiveness of state-level firearm legislation depends upon particular characteristics of counties.

Impact of Casino Gambling on Crime in the Atlantic City Region, 1970-1984 (ICPSR 9237)

Released/updated on: 2006-01-18
Geographic coverage: Atlantic City, United States, New Jersey
The aim of this data collection was to gauge the impact of legalized casino gambling on the level and spatial distribution of crime in the Atlantic City region by comparing crime rates before and after the introduction of this type of gambling in the area. Data for the years 1972 through 1984 were collected from various New Jersey state publications for 64 localities and include information on population size and density, population characteristics of race, age, per capita income, education and home ownership, real estate values, number of police employees and police expenditures, total city expenditure, and number of burglaries, larcenies, robberies and vehicle thefts. Spatial variables include population attributes standardized by land area in square miles, and measures of accessibility, location, and distance from Atlantic City. For the 1970/1980 data file, additional variables pertaining to population characteristics were created from census data to match economic and crime attributes found in the 1972-1984 data. Data on eight additional locations are available in the 1970/1980 file.

Impact of Immigration on Ethnic-Specific Violence in Miami, Florida, 1997 (ICPSR 3872)

Released/updated on: 2005-11-04
Geographic coverage: United States, Florida, Miami
Does the rate of violent victimization differ across race and ethnic groups? In an effort to answer this question, this study sought to examine the violent victimization rate and the factors influencing ethnic-specific rates of violence in the city of Miami. Administrative data were obtained from the United States Bureau of the Census and the Miami Police Department Research Unit. For the groups of people identified as Afro Americans, Latinos, and Haitians, the numbers who were victims of aggravated assault and robbery in 1997 are included along with the assault and robbery rates for each group. The remaining variables are the percent of female-headed households, percent below poverty line, percent of young males out of the labor force and unemployed, residential instability, vacant and household instability, and the percent of 1980-1990 immigrants.

Impact of Sentencing Guidelines on the Use of Incarceration in Federal Criminal Courts in the United States, 1984-1990 (ICPSR 9845)

Released/updated on: 2000-06-05
Geographic coverage: United States
Time period: 1984-07-01--1990-08-01
The primary purpose of this data collection was to examine the impact of the implementation of sentencing guidelines on the rate of incarcerative and nonincarcerative sentences imposed and on the average length of expected time to be served in incarceration for all offenses as well as for select groups of offenses. The measure of sentence length, "expected time to be served," was used to allow for assumed good time and parole reductions. This term represents the amount of time an offender can expect to spend in prison at the time of sentencing, a roughly equivalent standard that can be measured before and after the implementation of federal criminal sentencing guidelines in 1987. Three broad offense categories were studied: drug offenses, robbery, and economic crimes. Drug offenses include a wide range of illegal activities involving marijuana, heroin, and cocaine. Robbery includes bank and postal robbery (both armed and unarmed) as well as other types of robbery offenses that appear less frequently in the federal system, such as carrying a firearm during the commission of a robbery. Economic offenses include fraud (bank, postal, and other), embezzlement (bank, postal, and other), and tax evasion. Other monthly data are provided on the number of prison and probation sentences for all offenses and by offense categories.

Improving the Investigation, Clearance Rates, and Victim Restoration of Robberies: A Randomized Controlled Experiment, Seattle, Washington, Rochester, New York, 2021-2023 (ICPSR 39101)

Released/updated on: 2024-07-30
Geographic coverage: Seattle, United States, Rochester (New York), New York (state), Washington
Time period: 2021-01-01--2023-01-01

Clearance rates for most crimes have remained low and stable for decades (Braga et al., 2011), despite advances in police technologies (Koper et al., 2015). Many police agencies have developed triaging practices for criminal investigations using solvability factors to guess which cases are most likely to be solved and to allocate investigative resources to those crimes (Eck, 1983; 1992). This practice partially stems from a persistent belief that resolving crimes and the resulting clearance rates are due to circumstances of the crime and community context, and are beyond the control of police. However, a growing body of research has challenged this belief, demonstrating that enhanced investigative efforts can improve crime clearance rates beyond solvability factors (Braga and Dusseault, 2018; Lum and Wellford, 2023).

In this study, the research team sought to determine if investigative follow-ups could increase clearance rates for robbery and burglary cases (frequently occurring crime types with traditionally low clearance rates) and increase victim satisfaction with police services. Agencies selected for the study were the Seattle Police Department (SPD) in Seattle, Washington, and the Rochester Police Department (RPD) in Rochester, New York. Both agencies triaged a large proportion of robbery cases and would have a large enough sample size to successfully carry out an experiment.

The original study design was a randomized controlled trial. In both sites, robbery cases would be allocated to either the intervention condition--an investigative follow-up conducted by an officer during their daily patrol assignment--or the control condition with no follow-up. Challenges to personnel and agency funding from the COVID-19 pandemic, the murder of George Floyd, and other officer-involved deaths in 2020 led to difficulties implementing the study as initially designed. The experiment was not initiated in Rochester, and initiated but not completed in Seattle. Therefore, the team transitioned to a natural quasi-experiment design in Rochester and added a case analysis of robberies in Seattle.

This collection contains three datasets: victim satisfaction surveys from Seattle (DS1, n=39) and Rochester (DS2, n=37), and supplemental reports on follow-ups made during the Seattle experiment implementation (DS3, n=82).

Time period: 2006-01-01--2009-01-01

This study collection sought to thoroughly understand the creation, testing, and use of forensic science in five jurisdictions across the country. A random sample was selected of recent criminal cases in the following jurisdictions and tracked from investigation to adjudication to understand how forensic evidence functions:

  • Sacramento County, CA: 990 cases
  • Segwick County, KS: 936 cases
  • Allegheny County, PA: 978 cases
  • Bexar County (San Antonio), TX: 936 cases
  • King County, WA: 892 cases

The Principal Investigator sought answers to the following seven primary research questions:

  • How often is forensic evidence collected and analyzed and how is it used pre-arrest?
  • What are the outcomes of forensic evidence testing?
  • What is the effect of forensic evidence on arrest and charging?
  • How does forensic evidence affect the plea-bargaining process?
  • What effect does forensic evidence have on conviction and sentencing outcomes?
  • Does the turnaround time for analysis of forensic evidence have any impact on case disposition?
  • Does the institutional configuration of the crime laboratory have any effect on its productivity?

Data for the following types of forensic testing are included in this data collection: hair, fibers, glass, paint, gas chromatography / mass spectrometry (GC/MS), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy / energy dispersive x-ray spectroscopy (SEM/EDX), physical match, drug identification, toxicology, serology, combined DNA index system (CODIS), DNA short tandem repeat (Y-STR), blood pattern, test fire, and comparison scope.

Influence of Sanctions and Opportunities on Rates of Bank Robbery, 1970-1975: [United States] (ICPSR 8260)

Released/updated on: 1992-02-16
Time period: 1970-01-01--1975-01-01
This study was designed to explain variations in crime rates and to examine the deterrent effects of sanctions on crime. The study concentrated on bank robberies, but it also examined burglaries and other kinds of robberies. In examining these effects the study condidered three sets of factors: (1) Economic considerations-- the cost/benefit factors that individuals consider in deciding whether or not to perform a crime, (2) Degree of anomie--the amount of alienation and isolation individuals feel toward society and the effect of these feelings on the individuals' performing a crime, and (3) Opportunity--the effect of exposure, attractiveness, and degree of guardianship on an object being taken. These factors were explored by gathering information on such topics as: crime clearance rates, arrests, and sentences, bank attributes, and socioeconomic and demographic information.

Intercity Variation in Youth Homicide, Robbery, and Assault, 1984-2006 [United States] (ICPSR 30981)

Released/updated on: 2012-09-20
Geographic coverage: United States
Time period: 1984-01-01--2006-01-01
The research team collected data on homicide, robbery, and assault offending from 1984-2006 for youth 13 to 24 years of age in 91 of the 100 largest cities in the United States (based on the 1980 Census) from various existing data sources. Data on youth homicide perpetration were acquired from the Supplementary Homicide Reports (SHR) and data on nonlethal youth violence (robbery and assault) were obtained from the Uniform Crime Reports (UCR). Annual homicide, robbery, and assault arrest rates per 100,000 age-specific populations (i.e., 13 to 17 and 18 to 24 year olds) were calculated by year for each city in the study. Data on city characteristics were derived from several sources including the County and City Data Books, SHR, and the Vital Statistics Multiple Cause of Death File. The research team constructed a dataset representing lethal and nonlethal offending at the city level for 91 cities over the 23-year period from 1984 to 2006, resulting in 2,093 city year observations.

Local-Area Crime Survey, [United States], 2015, 2016 (ICPSR 38920)

Released/updated on: 2024-04-29
Geographic coverage: United States
Time period: 2015-09-01--2015-12-01, 2016-09-01--2016-12-01

The Bureau of Justice Statistics (BJS) entered into a cooperative agreement with Westat to develop and evaluate a lower-cost, subnational companion survey of victimization as one piece of the subnational estimates program. The Local-Area Crime Survey (LACS) was fielded in 2015 and 2016 and is intended for use by states, municipalities, or other jurisdictions and entities to assess levels and trends in public safety. The LACS is modeled in part after the National Crime Victimization Survey (NCVS), conducted for BJS by the U.S. Census Bureau. One of the two major statistical programs on crime produced by the U.S. Department of Justice, the NCVS is the nation's primary source of information about criminal victimization, whether reported or not reported to police. The core NCVS methodology includes a mix of in-person and telephone interviews with household members age 12 and older selected from an area probability sample to produce reliable national-level estimates. As another part of the subnational estimates program, BJS worked with the Census Bureau to enhance and reallocate the NCVS sample to support subnational estimates for the 22 most populous states and potentially substate areas within those states. For the most part, this direct estimation component of the program will not support estimates at the local level. See the NCVS Subnational Estimates webpage on the BJS website for more information.

The goals of this research were to (1) develop and test a relatively inexpensive survey design (2) that could be administered by local jurisdictions or their vendors (3) to produce cross-jurisdiction estimates and estimates of change over time within jurisdictions that may be compared with similar estimates using NCVS data. In addition to questions about victimization experiences, the LACS included questions about perceptions of community safety and police efficacy. The rationale for including these items was that they were relevant to all households, not just victims. The hope was that these items would increase survey response rates as non-victims would have important questions to answer. The LACS served as a platform for assessing the value of these questions for the planned NCVS instrument redesign. For more information, see the NCVS Instrument Redesign webpage on the BJS website.

Measure 11 Sentencing Reform in Oregon: Implementation and System Impact, 1990-1999 (ICPSR 4087)

Released/updated on: 2006-01-18
Geographic coverage: Oregon, United States
Time period: 1990-01-01--1999-01-01
This study explored the implementation and impact of Measure 11 (passed by Oregon voters in 1994), which imposed long mandatory prison terms for 16 designated violent and sex-related offenses, prohibited "earned time," and provided for mandatory waiver of youthful offenders to adult court. Measure 11 penalties were longer than those imposed under sentencing guidelines. Juveniles aged 15 years or older were also subject to the measure. The researchers addressed the implementation and impact of the measure on prosecution, sentencing, and convictions, both statewide and in three separate counties based on the Oregon Criminal Justice Commission (OCJC) data and the Oregon Department of Corrections (DOC) data. Variables include offender characteristics, plea trial information, number of convictions, prison term for convictions, severity of offense, M11-eligible and alternate offense, and description of most severe offense.

Measuring Crime Rates of Prisoners in Colorado, 1988-1989 (ICPSR 9989)

Released/updated on: 2005-11-04
Geographic coverage: United States, Colorado
Time period: 1988-07-01--1989-12-01
In the late 1970s, the Rand Corporation pioneered a method of collecting crime rate statistics. They obtained reports of offending behavior--types and frequencies of crimes committed--directly from offenders serving prison sentences. The current study extends this research by exploring the extent to which variation in the methodological approach affects prisoners' self-reports of criminal activity. If the crime rates reported in this survey remained constant across methods, perhaps one of the new techniques developed would be easier and/or less expensive to administer. Also, the self-reported offending rate data for female offenders in this collection represents the first time such data has been collected for females. Male and female prisoners recently admitted to the Diagnostic Unit of the Colorado Department of Corrections were selected for participation in the study. Prisoners were given one of two different survey instruments, referred to as the long form and short form. Both questionnaires dealt with the number of times respondents committed each of eight types of crimes during a 12-month measurement period. The crimes of interest were burglary, robbery, assault, theft, auto theft, forgery/credit card and check-writing crimes, fraud, and drug dealing. The long form of the instrument focused on juvenile and adult criminal activity and covered the offender's childhood and family. It also contained questions about the offender's rap sheet as one of the bases for validating the self-reported data. The crime count sections of the long form contained questions about motivation, initiative, whether the offender usually acted alone or with others, and if the crimes recorded included crimes against people he or she knew. Long-form data are given in Part 1. The short form of the survey had fewer or no questions compared with the long form on areas such as the respondent's rap sheet, the number of crimes committed as a juvenile, the number of times the respondent was on probation or parole, the respondent's childhood experiences, and the respondent's perception of his criminal career. These data are contained in Part 2. In addition, the surveys were administered under different conditions of confidentiality. Prisoners given what were called "confidential" interviews had their names identified with the survey. Those interviewed under conditions of anonymity did not have their names associated with the survey. The short forms were all administered anonymously, while the long forms were either anonymous or confidential. In addition to the surveys, data were collected from official records, which are presented in Part 3. The official record data collection form was designed to collect detailed criminal history information, particularly during the measurement period identified in the questionnaires, plus a number of demographic and drug-use items. This information, when compared with the self-reported offense data from the measurement period in both the short and long forms, allows a validity analysis to be performed.

This study reexamined and recoded missing data in the Uniform Crime Reports (UCR) for the years 1977 to 2000 for all police agencies in the United States. The principal investigator conducted a data cleaning of 20,067 Originating Agency Identifiers (ORIs) contained within the Offenses-Known UCR data from 1977 to 2000. Data cleaning involved performing agency name checks and creating new numerical codes for different types of missing data including missing data codes that identify whether a record was aggregated to a particular month, whether no data were reported (true missing), if more than one index crime was missing, if a particular index crime (motor vehicle theft, larceny, burglary, assault, robbery, rape, murder) was missing, researcher assigned missing value codes according to the "rule of 20", outlier values, whether an ORI was covered by another agency, and whether an agency did not exist during a particular time period.

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.

They were done to determine the most effective reference period to use when questioning respondents in order to gain the fullest and most reliable information, to measure the degree to which respondents move incidents occurring outside the reference period into that period when questioned, and to explore the possibility of identifying incidents by a few broad general questions as opposed to a series of more specific probing questions.

This data collection is an extract created from the individual years of the National Crime Victimization Survey. Each record contains information on a crime incident occurring in the given calendar year. Part 1 contains all crime incidents, and data Part 2 contains the crimes of rape and attempted rape only. The National Crime Victimization Survey (NCVS), previously called the National Crime Surveys (NCS), has been collecting data on personal and household victimization through an ongoing survey of a nationally-representative sample of residential addresses since 1973. The NCVS was designed with four primary objectives: (1) to develop detailed information about the victims and consequences of crime, (2) to estimate the number and types of crimes not reported to the police, (3) to provide uniform measures of selected types of crimes, and (4) to permit comparisons over time and types of areas. The survey categorizes crimes as "personal" or "property." Personal crimes include rape and sexual attack, robbery, aggravated and simple assault, and purse-snatching/pocket-picking, while property crimes include burglary, theft, motor vehicle theft, and vandalism. Each respondent is asked a series of screen questions designed to determine whether she or he was victimized during the six-month period preceding the first day of the month of the interview. A "household respondent" is also asked to report on crimes against the household as a whole (e.g., burglary, motor vehicle theft). The data include type of crime, month, time, and location of the crime, relationship between victim and offender, characteristics of the offender, self-protective actions taken by the victim during the incident and results of those actions, consequences of the victimization, type of property lost, whether the crime was reported to police and reasons for reporting or not reporting, and offender use of weapons, drugs, and alcohol. Basic demographic information such as age, race, gender, and income is also collected, to enable analysis of crime by various subpopulations.
