  • Juvenile violence peaks in the afterschool hours on school days and in the evenings on nonschool days.
  • On nonschool days, the incidence of juvenile violence increases through the afternoon and early evening hours, peaking between 7 p.m. and 9 p.m.
  • The number of school days in a year is essentially equal to the number of nonschool days in a year. Despite this split, most (63%) violent crimes committed by juveniles occur on school days. Nearly one-fifth (19%) of juvenile violent crimes occur in the 4 hours between 3 p.m. and 7 p.m. on school days. A smaller proportion of juvenile violent crime (15%) occurs during the standard juvenile curfew hours of 10 p.m. to 6 a.m. (inclusive of both school and nonschool days).
  • The annual number of hours in the curfew period (i.e., 8 hours every day in the year) is 4 times greater than the number of hours in the 3 p.m. to 7 p.m. period on school days (i.e., 4 hours in half of the days in the year). Therefore, the rate of juvenile violence in the afterschool period is 5 times the rate in the juvenile curfew period (inclusive of both school and nonschool days).
  • Consequently, efforts to reduce juvenile crime after school would appear to have greater potential to decrease a community’s violent crime rate than do juvenile curfews.
