| 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 two or more races. | |||||||||||||||||||||
| 3 Refers to the Standard Metropolitan Statistical Area (MSA) status of the respondent’s household as defined in 2000 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)." | |||||||||||||||||||||
| NOTE: "On school property" was not defined for survey respondents. The term "anywhere" was not used in the YRBS questionnaire; students were simply asked how many times in the last 12 months they had been in a physical fight. | |||||||||||||||||||||
