Fig. 4-1-1-1 shows the trends in the number of juveniles cleared for penal code offenses and their rates (the number of cleared juvenile offenders per 100,000 juveniles aged 10 and over but less than 20) since 1946 (see Appendix 4-1 ). The trends in the number of juveniles cleared for penal code offenses indicate 3 cycles, the first peaking in 1951 at 166,433, the second in 1964 at 238,830, and the third in 1983 at 317,438.
  The number of juveniles cleared and relevant rates had shown upward trends since 1996, but again went on a downward trend in 1999 and 2000. In 2001, the number of cleared juveniles reached 198,939 (up 2.9% from the previous year), equivalent to 1448.6 persons per 100,000 juveniles (up 5.2% from the previous year).

   Fig. 4-1-1-2 shows the trends in the number of juveniles and adults cleared for penal code offenses excluding professional negligence in traffic accidents as well as the juvenile rate (the proportion of juveniles cleared for penal code offenses to the total number of persons cleared, including adults and juvenile offenders under 14) since 1966, the year in which Criminal Statistics by the National Police Agency established the foundation of penal code offenses excluding professional negligence in traffic accidents.
  Although the number of juveniles cleared for penal code offenses other than professional negligence in traffic accidents increased from 1975, and sharply rose as if forming a big wave until the first half of the 1980s, and repeated the increase and decrease, and increased to 158,721 (up 3.9% from the previous year) in 2001. The juvenile rate was less than 50% after 1999, and was 46.0% in 2001.
