‡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 Race categories exclude persons of Hispanic ethnicity.

NOTE: Detail may not sum to totals because of rounding.
