(1) Number of juveniles newly admitted to juvenile training schools
  Fig. 4-2-4-1 shows the number of juveniles newly admitted to juvenile training schools by sex since 1949.
  The number of newly admitted juveniles increased sharply in the 1950s due to the postwar chaos of the society and economy, generally remaining in the range of 8,000 to 12,000, but continued declining after that to hit the bottom at 1,969 in 1974. However, the number started to increase again and has been around 4,000 to 6,000 in recent years (see Appendix 4-12).
