‡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 during the previous 30 days they had at least one drink of alcohol.

2 In the question about drinking alcohol at school, "on school property" was not defined for survey respondents.

3 Data on alcohol use at school were not collected from 2013 onward.

4 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.
