title: National Crime Surveys: National Sample, 1986-1992 [Near-Term Data]
title: Version 6

description: The objective of the National Crime Surveys is to provide data on the level of crime victimization in the United States and to collect information on the characteristics of crime incidents and victims. Each respondent was asked a series of screen questions to determine if he or she was victimized during the six-month period preceding the first day of the month of the interview. Screen questions cover the following types of crimes, including attempts: rape, robbery, assault, burglary, larceny, and motor vehicle theft. The data include type of crime, description of the offender, severity of the crime, injuries or losses, and demographic information on household members such as age, sex, race, education, employment, median family income, marital status, and military history.
description: 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: Standardized missing values.; Checked for undocumented or out-of-range codes..

description: (1) The National Crime Surveys data are organized by year, with six collection quarters comprising an annual file: the four quarters of the current year plus the first two quarters of the following year. (2) Parts 1-8 of this collection were the original collection quarter files from the Census Bureau, which are not available for public release. (3) The data for the Full Files and the Longitudinal File (Part 40) are hierarchically structured with four levels: Address or Household ID, Household, Person, and Incident. The Address or Household ID and Household levels contain 29,572 to 232,904 records per file. The Address or Household ID level has 5 to 41 variables and a logical record length of 54 to 77 per file. The Household level consists of 91 to 94 variables with a logical record length of 165 to 189 per file. The Person level has 51,762 to 392,547 records, 50 to 55 variables, and a logical record length of 104 to 124 per file. The Incident level contains 4,489 to 35,054 records and 499 to 500 variables, with a logical record length of 609 to 639 per file. Only incidents within the calendar year have been included in the person-level extract files, up to a maximum of four incidents per person. A 10-percent random sample of all persons without incidents also has been included. Persons without incidents also have been bounded by calendar year. Each case or person in the person-level files contains all Household, Person, and Incident variables from the hierarchical Full Files, including Variables 2001-2091, 3001-3050, and 4001-4499. Variables 5001-5499, 6001-6499, and 7001-7499 represent the second, third, and fourth incidents. For respondents with fewer than four incidents, the Incident record variables contain missing data codes. The Incident files include information on victims rather than nonvictims. There are three types of Incident files: single-year, concatenated annual, and rape subset. In all three types, an Incident record has been extracted from one of the hierarchical Full Files. These Incident records contain a victim's Household and Person information. Users working with the Person or Incident files should refer to the codebook documenting the hierarchical Full Files for methodological information and appropriate code values. (4) SAS data definition statements are available for Parts 15, 31, 33-38, and 42-49. SPSS data definition statements are provided for Parts 15, 30-38, and 42-49. (5) The Codebook for All Parts Except Part 40, including the data collection instrument for all parts, is available in ASCII text format. The Codebook for Part 40, with a copy of the data collection instrument for all parts, is provided as a Portable Document Format (PDF) file. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided on the ICPSR Web site.
