!Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.
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 Before 1999, Asian students and Pacific Islander students were not categorized separately, and students could not be classified as Two or more races. Because the response categories changed in 1999, caution should be used in comparing data on race from 1993 and 1997 with data from later years.
3 Students were asked which sexual orientation--"heterosexual (straight)," "gay or lesbian," "bisexual," or “not sure"--best described them.
4 Refers to the Standard Metropolitan Statistical Area (MSA) status of the respondent’s household as defined by the U.S. Census Bureau. Categories include "central city of an MSA (Urban)," "in MSA but not in central city (Suburban)," and "not MSA (Rural)."
5 In the question asking students about carrying a weapon at school, "on school property" was not defined for survey respondents.
NOTE: Respondents were asked about carrying "a weapon such as a gun, knife, or club." Race categories exclude persons of Hispanic ethnicity.
