!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 survey respondents.
3 Students were asked which sexual orientation--"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.
