This sample of the National Crime Survey contains information about victimization in 26 central cities in the United States. The data are designed to achieve three primary objectives: 1) to develop detailed information about the victims and consequences of crime, 2) to estimate the numbers and types of crimes not reported to police, and 3) to provide uniform measures of selected types of crimes and permit reliable comparisons over time and between areas of the country. Information about each household or personal victimization was recorded. The data include type of crime (attempts are covered as well), description of offender, severity of crime, injuries or losses, time and place of occurrence, age, race and sex of offender(s), relationship of offenders to victims, education, migration, labor force status, occupation, and income of persons involved.
