!Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.

‡Reporting standards not met. Either there are too few cases for a reliable estimate or the coefficient of variation (CV) is 50 percent or greater.

1 The term "anywhere" is not used in the Youth Risk Behavior Survey (YRBS) questionnaire; students were simply asked how many days they carried a weapon during the past 30 days.

2 In the question asking students about carrying a weapon at school, "on school property" was not defined for respondents.

3 Students were asked which of the following--"heterosexual (straight)," "gay or lesbian," "bisexual," or “not sure"--best described them.

NOTE: Respondents were asked about carrying "a weapon such as a gun, knife, or club." Race categories exclude persons of Hispanic ethnicity. Detail may not sum to totals because of rounding and the suppression of cells that do not meet National Center for Education Statistics reporting standards.
