National Crime Victimization Survey: Unbounded Data, 2002

The National Crime Victimization Survey: Unbounded Data (also referred to as the All Rotations Data) are now being made available to the public for analytic use. These data differ from the "regular" National Crime Victimization Survey (NCVS) data in that they contain the first interview with respondents. The National Crime Victimization Survey 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.

《全国犯罪受害者调查：无限制数据》（亦称所有轮次数据）现面向公众开放，供分析使用。此数据集与通常的《全国犯罪受害者调查》（NCVS）数据不同，因为它包含了受访者的首次访谈数据。自1973年以来，全国犯罪受害者调查系列（原称全国犯罪调查，NCS）通过对全国代表性样本住宅地址的持续调查，收集了有关个人和家庭受害者情况的数据。该调查旨在实现四个主要目标：（1）详尽了解犯罪受害者和犯罪后果的信息，（2）估算未向警方报告的犯罪数量和类型，（3）提供选定犯罪类型的统一度量标准，（4）允许在不同时间和不同类型区域之间进行比较。调查将犯罪分为“个人犯罪”和“财产犯罪”。个人犯罪包括强奸和性攻击、抢劫、严重和轻微攻击以及钱包盗窃/口袋盗窃，而财产犯罪包括盗窃、汽车盗窃和破坏。每位受访者都会被问到一系列筛选问题，以确定其是否在访谈月份的第一天之前的六个月内遭受了犯罪侵害。此外，对于“家庭受访者”，还会要求其报告针对整个家庭的犯罪（例如，盗窃、汽车盗窃）。数据包括犯罪类型、犯罪月份、时间、地点、受害者和犯罪者之间的关系、犯罪者特征、受害者在事件中采取的自我保护措施及其结果、受害者受害后果、失去的财产类型、犯罪是否报告给警方以及报告或不报告的原因，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数据，如年龄、种族、性别和收入，以便分析不同子群体的犯罪情况。
