National Crime Victimization Survey, 2011 (ICPSR 34061)
Principal Investigator(s): United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
The National Crime Victimization Survey (NCVS) Series, 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. This version of the NCVS, referred to as the collection year, contains records from interviews conducted in the 12 months of the given year.
These data are available to the general public.

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, individual, crime incident
Universe: All persons in the United States aged 12 and over.
Data Types: survey data
Data Collection Notes:
The 2011 Collection Year Incident-Level Extract File was created from the record-type files and includes information on victims of crime; nonvictims are not included. Under the collection year format a crime incident is included based on when the interview is conducted, not on when the crime incident occurred.
The data were collected by the United States Department of Commerce, Bureau of the Census.
The 2011 data contain replicate weights for household, person, incident, and victimization to facilitate standard error computations given the sampling design of NCVS.
Sample: Stratified multistage cluster sample.
Weight: The data files include several weight variables used to calculate national estimates of: households, persons, victimizations, and incidents. The codebook describes how to use the weights.
Mode of Data Collection: computer-assisted personal interview (CAPI), face-to-face 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.
Restrictions: This data collection may not be used for any purpose other than statistical reporting and analysis. Use of these data to learn the identity of any person or establishment is prohibited.
Original ICPSR Release: 2012-10-25
- 2013-12-06 The data for quarters 2 through 4 were updated to reflect a change in the computation of time in the sample. This affected weighting adjustment factors and subsequently affected the victimization weights in the dataset.
