title: National Crime Surveys: National Sample, 1986-1992 [Near-Term Data]
title: Version 7

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: (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.
