A total of 79,707 cases of shoplifting were documented, primarily of perfumes and cosmetics. Other major thefts occurred in the areas of dried food, smoking-related items, women's clothing, and stationery, in that order. Unmarried men and women were involved in shoplifting significantly more often than married persons, and married women were involved nearly twice as often as married men. The greatest number of thefts was committed by students, followed by blue-collar workers and unemployed persons. Based on the reports obtained, incidents of shoplifting were traced by Province or city, day, and hour. Although no definitive conclusions can be drawn from these preliminary data, the patterns and profiles generated by statistical analysis of the findings may be useful in devising preventive strategies. During the survey period, 477 letters were sent to parents of youthful offenders. Although parents' reactions were overwhelmingly positive, merchandise-distributing enterprises do not seem sufficiently equipped to mount an effective prevention campaign aimed at minors. Any meaningful campaign against shoplifting will require collaboration at many levels. Tables and footnotes are supplied.
