In 2006, about 10 percent of Philadelphia's 406 homicide victims were younger than 18. That year, in response to concerns about increasing youth violence, Mayor John Street opened the city's first curfew center. The goal of the South Philadelphia center was to prevent and reduce violence by enforcing curfew laws and helping children and their parents get access to important services and resources. Since the center opened, juvenile shootings have dropped about 50 percent in the areas it serves, and the program has expanded to six curfew centers across the city, with six more expected to open by the end of the year. Open from 9 p.m. to 8 a.m. most nights, each curfew center is staffed by a combination of city and private social services staff and neighborhood volunteers. Police bring curfew violators to the centers, where trained professionals assess each child and their parents or guardians, and refer them to any programs or services deemed necessary. If a parent or guardian can't be located, the center provides kids with food and a room to sleep in until they can be turned over to the Department of Human Services in the morning. The curfew centers are part of Mayor Street's Operation Safer Streets program. To learn more about it, visit www.phila.gov/saferstreets.
