Descriptive statistics for underrepresented minority 11th and 12th grade students in the 1991–2015 survey waves of the YRBS and 19- to 30-year-old adults in the 1992–2015 survey waves of the TUS-CPS who were likely high school juniors between 1991 and 2015 (i.e., individuals who had attained 16 years of age at any time point between 1990 and 2015). For ease of presentation, the YRBS summary statistics are based on the sample used to estimate the regression models for cigarette smoking (n = 36,268). Descriptive statistics using estimation samples from the other regression models were similar. Reported numbers represent raw counts. Percentages and means were computed using sample weights.
