Violent youth crimes fell by 64 percent between 2008 and 2018 (Figure 1). For the last three years, the San Francisco Police Department (SFPD) has failed to specify the offense type for nearly 90 percent of youth arrests in San Francisco (CJCJ, 2018). However, arrest data over the last ten years show declines in violent arrests across all age groups, with youth accounting for the largest drop (SFPD, 2019). In June 2019, the San Francisco Board of Supervisors passed an ordinance which outlines a plan to close the county's juvenile hall by the end of 2021 (BOS, 2019). The decision is based on the unprecedented decline in San Francisco youth crime over the past decade which has resulted in a concurrent decline in the juvenile hall population (Tucker, 2019). Today, with a design capacity of 150, San Francisco's juvenile hall houses less than 30 youth (SFJPD, 2019).
