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 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.
4 Ohio data for 2005 through 2013 include both public and private schools.
5 South Dakota data for 2005 through 2015 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 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).
