Estimates do not include youth who dropped out of school and therefore may not reflect total national values. Students from California, Oregon, Washington, and
Minnesota were not included in the survey in any year. Additionally, students from Colorado, Iowa, Indiana, and Pennsylvania were not included in the 2013
survey.

Race/ethnicity estimates from 1999 and later are not directly comparable to earlier years due to federal changes in race definitions. In surveys conducted in 1999
and later, respondents were allowed to select more than one race when selecting their racial category. Estimates presented only include respondents who
selected one category when choosing their race.
