National Archive of Criminal Justice Data
This dataset is maintained and distributed by the National Archive of Criminal Justice Data (NACJD), the criminal justice archive within ICPSR. NACJD is primarily sponsored by three agencies within the U.S. Department of Justice: the Bureau of Justice Statistics, the National Institute of Justice, and the Office of Juvenile Justice and Delinquency Prevention .
National Crime Victimization Survey, 1992-2005: Concatenated Incident-Level Files (ICPSR 4699)
Alternate Title: NCVS, 2005
Principal Investigator(s): United States Department of Justice. Bureau of Justice Statistics
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.
These data are freely available.

This survey was funded by:
- United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
Scope of Study
Subject Terms: assault, auto theft, burglary, crime, crime costs, crime rates, crime reporting, crime statistics, offenders, offenses, property crimes, rape, reactions to crime, robbery, sexual offenses, vandalism, victimization, victims
Smallest Geographic Unit: region
Geographic Coverage: United States
Date of Collection:
Unit of Observation: household, person, crime incident
Universe: All persons in the United States aged 12 and over.
Data Types: survey data
Data Collection Notes:
Starting with year 2005, ICPSR split the NCVS data files into two studies, one for the concatenated incident-level files (contained in this data collection) and one for the single-year files. This allows for more complete documentation of variables that were added or dropped since the inception of the NCVS is 1992.
Sample: Stratified multistage cluster sample.
Weight: The data include ADJUSTED VICTIMIZATION WEIGHT - DATA YEAR (WGTVICDY) to calculate an estimate of victimizations. These data do not include sufficient records to calculate an estimate of household or person counts. To calculate household or person counts refer to the data collections for individual years' of NCVS data.
Mode of Data Collection: computer-assisted telephone interview (CATI), face-to-face interview, telephone interview
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Performed consistency checks.
- Created variable labels and/or value labels.
- Standardized missing values.
- Performed recodes and/or calculated derived variables.
- Checked for undocumented or out-of-range codes.

Crime Victimization in the US: A Data-Driven Learning Guide - Inter-university Consortium for Political and Social Research
Crime victimization is defined as the involuntary, personal exposure to criminal acts. Victimization can be economic, physical, psychological and/or emotional.
It is difficult to know exactly how many crimes are committed and how many people are victimized every year because a significant percentage of crimes (almost half of violent crimes and about one third of property crimes) go unreported to, or undiscovered by, police. Criminologists refer to this unknown as the "dark figure of crime." By polling a large number of households, victimization surveys such as the National Crime Victimization Survey are able to uncover some of the crime incidents that were never reported or discovered by police. They also provide more detailed information about the crime, victim, and offender(s), than other official sources of crime statistics such as the FBI's Uniform Crime Reports. Victimization surveys are therefore an important source of data for criminologists, but they are not without their limitations. For example, they rely on respondents' honesty and ability to recall facts accurately; since they typically survey only people 12 and older, they provide no data on crimes committed against children; and since they survey crime victims, there is no data on murders either, for obvious reasons!
The goal of this exercise is to explore crime victimization in the US. Frequencies, crosstabulations and comparisons of means will be used.
