National Crime Victimization Survey, [United States], 2017

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.

国家犯罪受害者调查系列（National Crime Victimization Survey，简称NCVS），此前被称为国家犯罪调查（National Crime Surveys，简称NCS），自1973年起，通过对全国代表性住宅地址样本的持续调查，收集个人和家庭受害数据。该调查旨在实现四个主要目标：（1）详尽地收集犯罪受害者及其后果的信息，（2）估计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）允许对时间跨度和不同区域类型进行比较。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、加重和简单攻击，以及钱包扒窃/口袋翻找；而财产犯罪则包括入室盗窃、盗窃、机动车盗窃和破坏。每位受访者将被询问一系列筛选问题，以确定其在访谈月份的第一天前六个月内是否成为受害者。同时，“家庭受访者”还需报告针对整个家庭的犯罪情况（例如，入室盗窃、机动车盗窃）。数据包括犯罪类型、犯罪月份、时间、地点、受害者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其结果、受害后果、丢失的财产类型、是否向警方报告犯罪及其原因，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，以便对不同子群体进行犯罪分析。本版本的NCVS，即收集年份，包含该年12个月份进行的访谈记录。
