This report presents data from a 1999 survey of sixth graders in the District of Columbia. The survey asked students: (1) where they were; (2) what they were doing; and (3) who they were with the day before, on the hour and on the half hour, between 3:00 and 6:00 p.m. The surveys were administered on Wednesday, November 10, because the previous day was a typical school day. Out of about 160 schools, over 60 percent returned surveys. Data on over 3,400 sixth graders were collected, representing a cross-section of the city by poverty, ward, and school type. Overall, students spent most of their time at school until 4:00, then they spent a little over half of their time at home until 6:00. During those times, they spent significant amounts of time on homework. From 4:00-6:00, they also spent significant time watching television or playing computer games. Most students were with adults from 3:00-6:00, though significant numbers were without adults during this time. Students' activities, time spent with adults, and location after school varied by the type of school they attended (private, public religious, or charter). (SM)
