Survey results show that only about one-fourth of reported incidents involved serious violence (victim was at least hit by the offender). Of the estimated 630,000 incidents occurring during the year, less than 4 percent were reported to the police. Even for serious offenses, the amount of reported criminality only averaged 6 to 7 percent. Young people were the usual victims of violence and were most likely to refrain from reporting. Except for domestic violence, men were more likely than women to be victims of violence. Over 80 percent of the estimated 571,000 property offenses were not reported to the police. The most common object stolen was a bicycle, followed by electronic equipment, jewelry, clothing, cars, money, and securities. Graphs, tables, and 13 references.
