1. Weighted results mean that the overall response rate was at least 60%. The overall response rate is calculated by multiplying the school response rate times the student response rate. Weighted results are representative of all students in grades 6-8 or grades 7-8 attending public schools in each jurisdiction. With weighted data, it is possible to say, for example, "X% of students in state Y never or rarely wore a seat belt when riding in a car driven by someone else."

2. Unweighted data represent only the students who completed the survey.

3. Sites that have given CDC permission to distribute their data files to people interested in additional data analyses are represented by “Y”. Sites that have not given CDC permission to distribute their data files are represented by “N”; these sites will need to be contacted directly to arrange access to data files. Sites that do not have any years of weighted data are designated by “N/A”. See Requesting Data Files for more information.
