12th 3021 50.16 12015 31.05
Total 6023 100 38701 100

The number of 8th grade smokers has decreased 17.22 to 15.74%.

The number of 10th grade smokers has increased 32.95 to 34.10%.

The number of 12th grade smokers has increased 49.84 to 50.16%.

The number of 8th grade non-smokers has decreased 36.07 to 35.79%.

The number of 10th grade non-smokers has decreased 33.40 to 33.16%.

The number of 12th grade non-smokers has increased 30.53 to 31.05%.
