!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 times in the past 12 months they had been in a physical fight.

2 In the question asking students about physical fights at school, "on school property" was not defined for respondents.

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

NOTE: Race categories exclude persons of Hispanic ethnicity. Detail may not sum to totals because of rounding.
