NOTE: Data for 2005 have been revised from previously published figures. "At school" includes the school building, on school property, on a school bus, and, from 2001 onward, going to and from school. In 2005 and 2007, the unit response rate for this survey did not meet NCES statistical standards; therefore, interpret the data with caution. For more information, please see appendix A.
