Fig. 5-4-2-1 shows the trends in the number of persons newly received as parolees and probationers for homicide and 9 types of violent offenses, in terms of type of offense and type of disposition. As mentioned in Section 3 of Chapter 5 in Part 2 , juvenile parolees and probationers can be divided into 2 types: (a) juvenile probationers who were placed under probationary supervision by family courts ( Fig. 5-4-2-1(i) ); and (b) juvenile parolees who were provisionally discharged from juvenile training schools ( Fig. 5-4-2-1(ii) ). Additionally, adult parolees and probationers can be also divided into 2 types: (c) adult parolees who were provisionally discharged from penal institutions ( Fig. 5-4-2-1(iii) ); and (d) adult probationers who were granted a suspended sentence with probationary supervision ( Fig. 5-4-2-1(iv) ). In this section, we will examine these 4 types of parolees and probationers in terms of juveniles and adults.

Fig. 5-4-2-1 Trends in the number of persons newly placed under probationary supervision (1974-2001)

  The number of juveniles newly placed under probationary supervision has been remarkably increasing for robbery, bodily injury and extortion. It has increased remarkably since 1995, after being flat from around 1984 to 1994. Comparing the number of juveniles newly placed between 2001 and 1995 (hereinafter referred to as "short-term comparison"), the number in 2001 increased 1.7-fold from the 1995 level for robbery, 1.8-fold for bodily injury, and doubled for extortion. On the other hand, in comparison with 1974 (hereinafter referred to as "long-term comparison"), the increase was 3.2-fold for robbery, 4.7-fold for bodily injury, and 3.4-fold for extortion. The number of new juvenile parolees who were provisionally discharged from juvenile training schools has also been on the rise. In the short-term comparison, it was 2.9-fold for robbery, 2.1-fold for bodily injury, and 2.3-fold for extortion. On the other hand, in the long-term comparison, the increase was 5.6-fold for robbery, 11.7-fold for bodily injury, and 4.7-fold for extortion. Overall, in the short-term comparison, the number of new juvenile parolees who were provisionally discharged from juvenile training schools has increased remarkably and rapidly for robbery, and in the long-term comparison, it has increased remarkably for bodily injury.
  Furthermore, concerning breaking and entering and indecent assault, the number of juveniles newly placed under probationary supervision has increased in the long-term comparison, showing a 3-fold rise for breaking and entering, and a 1.7-fold rise for indecent assault. Incidentally, the number of rape offenses committed by juvenile parolees who were provisionally discharged from juvenile training schools has decreased in the past few years.

  By type of offense, the number of adults newly placed on probationary supervision is the highest for bodily injury. Trends in the number for bodily injury are similar to those in the number of reported cases for bodily injury (see Part 5, Chapter 2, Section 1-1 ), which started rising between 1998 and 2000 after having shown an overall decreasing trend for a long period.
  In terms of type of disposition and type of offense, in the long-term comparison, the number of parolees newly placed has increased for indecent assault (2.1-fold) and breaking and entering (1.3-fold), excluding intimidation on the ground that the number of offenders is small, which remained at levels below 20. On the other hand, in the short-term comparison, the number of parolees newly placed has increased for indecent assault (1.8-fold), robbery (1.5-fold), bodily injury (1.3-fold), rape (1.2-fold), and extortion (1.1-fold). Additionally, in the long-term comparison, the number of adults granted suspension of execution of sentence with probationary supervision has increased for indecent assault (1.9-fold), breaking and entering (1.8-fold), which has the same tendency as the parolees newly placed. In the short-term comparison, it has increased for bodily injury (1.6-fold) and extortion (1.5-fold).
