| 1 The term "anywhere" is not used in the Youth Risk Behavior Survey (YRBS) questionnaire; students were simply asked how many times in the past 12 months they had been in a physical fight. | ||||||||||||||||||||||||
| 2 In the question asking students about physical fights at school, "on school property" was not defined for survey respondents. | ||||||||||||||||||||||||
| 3 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. | ||||||||||||||||||||||||
| 4 Ohio data for 2005 through 2013 include both public and private schools. | ||||||||||||||||||||||||
| 5 South Dakota data for all years include both public and private schools. | ||||||||||||||||||||||||
| 6 Vermont data for 2013 include both public and private schools. | ||||||||||||||||||||||||
| NOTE: 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 (2005 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). | ||||||||||||||||||||||||
