†Not applicable.
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 Data include both public and private schools.
NOTE: Respondents were asked about carrying "a weapon such as a gun, knife, or club." State-level data include public schools only, with the exception of data for Ohio and South Dakota. Data for the United States total, Ohio, and South Dakota include both public and private schools.
