Findings presented in this bulletin show that the number of juvenile arrests in 2017 was at its lowest level since 1980, with much of the decline occurring within the past 10 years. The bulletin describes the current arrest trends for juveniles from 1980 to 2017, using data from the FBI’s Uniform Crime Report. Overall, juvenile arrests have been on the decline for more than a decade, but patterns vary by offense and demographics. For example, while both male and female juvenile arrests declined in the last 10 years, declines have been greater for males in many offense categories. Also, while juvenile arrest rates for aggravated assault have declined in the last 5 years, arrest rates for robbery have stayed about the same, and the juvenile arrest rate for murder has increased.
