The percentage of students in grades 9–12 who reported carrying a weapon anywhere during the previous 30 days decreased from 17 percent in 2009 to 13 percent in 2019. Similarly, the percentage of students who reported carrying a weapon on school property during the previous 30 days decreased from 6 to 3 percent during the same period.
This indicator uses data from the Youth Risk Behavior Surveillance System (YRBSS) to examine the percentages of students in grades 9–12 who reported carrying a weapon on school property and anywhere during the previous 30 days. Then, using data from the EDFacts data collection, the indicator presents, by state, the numbers of public school students reported by schools to have possessed firearms during the school year. It concludes with a discussion of data from the School Crime Supplement (SCS) to the National Crime Victimization Survey on students ages 12–18 who reported having access to a loaded gun at school or away from school during the school year without adult permission. Readers should take note of the differing data sources and terminology.

NOTE: Respondents were asked about carrying “a weapon such as a gun, knife, or club.” The term “anywhere” is not used in the Youth Risk Behavior Surveillance System (YRBSS) questionnaire; students were simply asked how many days they carried a weapon during the past 30 days. In the question asking students about carrying a weapon at school, “on school property” was not defined for respondents.

! 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.
1 Students were asked which of the following—“heterosexual (straight),” “gay or lesbian,” “bisexual,” or “not sure”—best described them.
NOTE: To estimate the margin of error, the standard error is scaled based on the desired level of confidence in the estimate. Throughout the Condition of Education, margins of error are produced based on a 95 percent level of confidence. Margin of error is calculated as 1.96*standard error.

1 The question on weapon carrying during the previous 30 days asked about these weapon types combined. Separate data on each type of weapon were not collected.

In the question asking students about carrying a weapon at school, “on school property” was not defined for respondents.
3 “Anywhere” includes on school property.
4 U.S. total data are representative of all public and private school students in grades 9–12 in the 50 states and the District of Columbia. U.S. total data were collected through a separate national survey rather than being aggregated from state-level data. In this indicator, all YRBSS discussions about weapon carrying, except those at the state level, are based on data from the national survey.
5 In 2019, state-level data on the percentage of students in grades 9–12 who reported carrying a weapon at least 1 day during the previous 30 days anywhere were available for 25 states and the District of Columbia (for detailed information by state, see the table on weapon carrying anywhere for all locations in the YRBSS Youth Online Data Analysis Tool).
6 Estimates by the number of days students reported carrying a weapon do not add up to the total because of rounding.
7 In 2019, state-level data on the percentage of students in grades 9–12 who reported carrying a weapon at least 1 day during the previous 30 days on school property were available for 37 states and the District of Columbia (for detailed information by state, see the table on weapon carrying on school property for all locations in the YRBSS Youth Online Data Analysis Tool.
8 Since 2015, the YRBSS has included a question on students’ sexual identity by asking students in grades 9–12 which of the following best described them—“heterosexual (straight),” “gay or lesbian,” “bisexual,” or “not sure.” In this indicator, students who identified as “gay or lesbian” or “bisexual” are discussed together as the “gay, lesbian, or bisexual” group. Students were not asked whether they identified as transgender in the YRBSS.
9 U.S. total includes the 50 states and the District of Columbia.
10 Analyses by school locale and control of school exclude students with missing information about the school characteristic.
