!Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.
‡Reporting standards not met. Either there are too few cases for a reliable estimate or the coefficient of variation (CV) is 50 percent or greater.
1Before 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, 1995, and 1997 with data from later years.
2From 2015 to 2019, students were asked which of the following best described them: "heterosexual (straight)," "gay or lesbian," "bisexual," or "not sure." In 2021, the response options were updated to include "heterosexual (straight)," "gay or lesbian," "bisexual," "I am not sure about my sexual identity (questioning)," "I describe my sexual identity in some other way," or "I do not know what this question is asking." Students who selected "I do not know what this question is asking" are considered to be missing the sexual identity variable and thus excluded from the analyses. Because the response categories changed in 2021, caution should be used in comparing data on sexual identity from 2021 with data from earlier years.
NOTE: Survey respondents were asked about being threatened or injured "with a weapon such as a gun, knife, or club on school property." "On school property" was not defined for respondents. Race categories exclude persons of Hispanic ethnicity.
