Description
NYTS is a school-based survey that collects information on tobacco use and related behaviors and attitude from middle school (grades 6-8) and high school (grades 9-12) students. NTYS includes measures on prevalence of youth tobacco use, smoking cessation, tobacco-related knowledge and attitudes, access to tobacco, media and advertising, and secondhand smoke exposure.

Selected Content
Use of cigarettes, cigars, smokeless tobacco, and other tobacco products within the past 30 days.
Population covered
U.S. students in grades 6 through 12.
Methodology
NYTS uses a three-stage cluster sampling design to generate a cross-sectional, nationally-representative sample of students in grades 6-12 from all 50 states and the District of Columbia. Data are adjusted for nonresponse and weighted to produce national prevalence estimates, while accounting for the complex survey design.
Response rate and sample size
In 2009, of 222 randomly sampled schools, 205 participated; of 24,266 students randomly selected at participating schools, 22,679 partipated, yielding an overall response rate of 84.8 percent.
Interpretation Issues
Since these data were collected from youths attending middle and high school, they may not be representative of all youths in the U.S. Youths who have dropped out of school are more likely to smoke than youths who are in school.
