The commercial victimization surveys, restricted to burglary and robbery incidents, include all types of commercial establishments as well as political, cultural, and religious organizations. The survey includes a series of questions about the business -- type, 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 are provided for each incident. A multistage cluster sample design was used to collect the data. Both victimized and nonvictimized establishments in 26 cities were interviewed during 1972, 1973, and 1974; 13 were reinterviewed in 1975. The data are contained in 39 hierarchical data files, 1 city per year; there are 166 variables for the 1,059-8,154 cases of combined business and incident records.
