! Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.
1 Race categories exclude persons of Hispanic ethnicity.
2 The response categories for race/ethnicity changed in 1999, making comparisons of some categories with categories of 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. "Weapon" was defined as a gun, knife, or club for survey respondents.
