!Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.
1 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 for all years were collected through a separate national survey (rather than being aggregated from state-level data) and include both public and private schools.
2 Ohio data for 2003 through 2013 include both public and private schools.
3 South Dakota data for 2003 through 2015 include both public and private schools.
4 Vermont data for 2013 include both public and private schools.
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. For the U.S. total, data for all years include both public and private schools. State-level data include public schools only, except where otherwise noted. For specific states, a given year's data may be unavailable (1) because the state did not participate in the survey that year; (2) because the state omitted this particular survey item from the state-level questionnaire; or (3) because the state had an overall response rate of less than 60 percent (the overall response rate is the school response rate multiplied by the student response rate).
