*
Sample increases between Survey 1 and Survey 2 as more youth are past month smokers at Survey 2 compared to Survey 1. Sample increases between Survey 2 and 3 due to recruitment of additional cohort of 12-year-olds at this time. Sample begins to decrease after survey 3 as more youth in the cohort reach their 18th birthday.

Four individuals are excluded from original MACC sample of 3,637 because their age sex or race was missing.
