| 1 In 2007, the reference period was the school year, whereas in prior survey years the reference period was the previous 6 months. Cognitive testing showed that estimates from 2007 are comparable to previous years. |
| NOTE: All gangs, whether or not they are involved in violent or illegal activity, are included. "At school" includes the school building, on school property, on a school bus, or 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 |
