National Crime Victimization Survey, Concatenated File, [United States], 1992-2021

The National Crime Victimization Survey (NCVS), previously called the National Crime Survey (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. Beginning in 1992, the survey categorizes crimes as "personal" or "property." Personal crimes include rape and sexual assault, 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 dataset represents the concatenated version of the NCVS on a collection year basis for 1992-2021. A collection year contains records from interviews conducted in the 12 months of the given year. Under the collection year format, victimizations are counted in the year the interview is conducted, regardless of the year when the crime incident occurred.For additional information on the dataset, please see the documentation for the data from the most current year of the NCVS, ICPSR Study 38429.

国家犯罪受害者调查（National Crime Victimization Survey，简称NCVS），曾命名为国家犯罪调查（National Crime Survey，简称NCS），自1973年起便通过针对全国代表性住宅地址样本的持续调查，收集个人与家庭受害者数据。该调查旨在实现四大主要目标：（1）详尽阐述犯罪受害者的信息及犯罪后果，（2）估算未向警方报告的犯罪数量及类型，（3）提供选定犯罪类型的统一度量标准，（4）允许对时间及不同区域类型进行比较。自1992年起，调查将犯罪分为“个人犯罪”和“财产犯罪”两大类别。个人犯罪包括强奸和性侵犯、抢劫、严重及轻微袭击、以及扒窃等，而财产犯罪则涵盖入室盗窃、盗窃、机动车盗窃及破坏行为。每位受访者需回答一系列筛选问题，以确定其是否在调查月的前六个月内遭受了犯罪侵害。此外，“家庭受访者”还需报告针对整个家庭发生的犯罪（例如，入室盗窃、机动车盗窃）。数据内容包括犯罪类型、犯罪月份、时间及地点、受害人与犯罪者之间的关系、犯罪者特征、受害者在事件中采取的自我保护措施及措施结果、受害后果、失窃财产类型、犯罪是否报告给警方及未报告的原因，以及犯罪者使用武器、毒品和酒精的情况。此外，还收集了基本的人口统计信息，如年龄、种族、性别和收入，以便对犯罪进行不同子群体的分析。本数据集为1992年至2021年期间NCVS的年度集合版本，每年集合包含该年度12个月份的调查记录。在集合年度格式下，犯罪受害者数据以调查进行年份计算，而不论犯罪事件发生的年份。如需了解有关数据集的更多信息，请参阅NCVS最新年度数据的文档，ICPSR研究编号38429。
