Fig. 1-1-1-8  Clearance rate for penal code offenses (1978–2007)

  The clearance rate, which used to be around 70% in overall number of penal code offenses, has been on the decline in recent years, as a sharp increase in the number of cases reported for penal code offenses overwhelmed the capacity of clearance. In 2001, it was 38.8% for penal code offenses and 19.8% for non-traffic penal code offenses, both of which were the lowest in the post WWII period. However, it has risen somewhat since 2002, to 51.6% (up by 0.6 points from the previous year) for penal code offenses and 31.7% (up by 0.5 points (id.)) for non-traffic penal code offenses in 2007.
