The proportion of students reporting that they carried a weapon in the past 30 days decreased from 26 percent in 1991 to 17 percent in 1999. Since then, the percentage has not strayed far from the current figure of 16 percent (as of 2015). However, between 2013 and 2015, there was a decrease in the proportion of students carrying weapons for all tabulated race/ethnicity groups. White students remained the most likely to carry weapons during this time period, at 18 percent in 2015. (Figure 1) Among white high school students, the proportion who carried a weapon on school property decreased from six to four percent in the same period, while the rate remained unchanged for Hispanic students and black students, at five and three percent, respectively.
