According to the British Crime Survey conducted in 1982 and 1992, 3 per cent of the population that is repeatedly victimized suffers about 25 per cent of all the crimes reported. The most common mistake made by those using statistics is to interpret crime incidence as the measure of the crime problem. In reality, repeated occurrences of crime against the same persons generate a different picture. Moreover, the Survey found that the risk of revictimization is greatest in the period immediately after victimization. This has two main policy implications: crime prevention measures need to be in place very soon after victimization, and temporary prevention measures, which provide cover during the high-risk period after victimization, may be an effective and efficient means of preventing crime.
