The National Crime Surveys, of which these Commercial Victimization Surveys are a part, were conducted to obtain current and reliable measures of serious crime in the United States. The Commercial Victimization Surveys are restricted to coverage of burglary and robbery incidents. They include all types of commercial establishments as well as political, cultural, and religious organizations. The survey includes a series of questions about the business, e.g., type and size, form of ownership, insurance, security, and break-in and robbery characteristics. Time and place, weapon, injury, entry evidence, offender characteristics, and stolen property data were collected for each of the incidents. Data on both victimized and nonvictimized establishments in 26 different cities were collected during 1972, 1973, and 1974. In the 1975 survey, data from the 13 cities surveyed during 1972 and 1973 were collected again.
