! Interpret data with caution.
1 Race categories exclude persons of Hispanic ethnicity.
2 The response categories for race/ethnicity changed in 1999 making comparisons of some categories with earlier years problematic. In 1993, 1995, and 1997, Asian students and Pacific Islander students were not categorized separately and students were not given the option of choosing more than one race.
NOTE: "On school property" was not defined for survey respondents. The term "anywhere" is not used in the YRBS questionnaire; students are simply asked how many days they carried a weapon during the past 30 days.
