National Crime Victimization Survey, Concatenated File, 1992-2015

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 dataset represents the concatenated version of the NCVS on a collection year basis for 1992-2015. 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, please see the documentation for the data from the most current year of the NCVS, ICPSR Study 36142.

全国犯罪受害调查（National Crime Victimization Survey, NCVS）系列前身为全国犯罪调查（National Crime Surveys, NCS），自1973年起，通过对具有全国代表性的居住地址样本开展持续性调查，收集个人与家庭受害相关数据。该调查设定四项核心目标：其一，全面获取犯罪受害者与犯罪后果的详细信息；其二，估算未向警方报案的犯罪数量与类型；其三，为选定的犯罪类型提供统一测量标准；其四，支持不同时期与不同区域类型间的犯罪情况对比。调查将犯罪划分为“人身犯罪”与“财产犯罪”两类：人身犯罪涵盖强奸与性侵犯、抢劫、加重与普通袭击，以及拎包盗窃/扒窃；财产犯罪则包括入室盗窃、盗窃、机动车盗窃与故意毁坏财物。每名受访者需回答一系列筛选问题，用以判断其在采访当月首日之前的六个月内是否遭遇犯罪侵害。此外，“家庭受访者”还需报告针对整个家庭的犯罪（例如入室盗窃、机动车盗窃）。数据集包含犯罪类型、案发月份、时间与地点、受害者与施害者的关系、施害者特征、受害者在事件中采取的自我保护措施及其效果、受害后果、失窃财产类型、案件是否向警方报案及报案/未报案的原因，以及施害者使用武器、毒品与酒精的情况。同时还收集年龄、种族、性别与收入等基础人口统计信息，以支持针对不同亚群体的犯罪相关分析。本数据集为1992-2015年按收集年度整合的NCVS合并版本。收集年度包含给定年份12个月内开展的采访记录。在收集年度格式下，受害事件被计入采访开展的年份，而非犯罪事件实际发生的年份。如需更多信息，请参阅NCVS最新年度数据的文档，即ICPSR研究项目36142。
