| 1 For the U.S. total, data for all years include both public and private schools and were collected through a national survey representing the entire country. The U.S. total includes only the 50 states and the District of Columbia. | ||||||||||||||
| 2 Ohio data for 2003 through 2013 include both public and private schools. | ||||||||||||||
| 3 South Dakota data for all years 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 three states, data for one or more years include both public and private schools: Ohio (2003 through 2013), South Dakota (all years), and Vermont (2013 only). 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). | ||||||||||||||
