Availability of Alcohol Among Youth As Measured by Monitoring The Future Study
"Perceived availability of alcohol, which until 1999 was asked only of 8th and 10th graders, was very high and mostly steady in the 1990s. Since 1996, however, there have been significant declines in 8th and 10th grades. For 12th grade, availability has declined only modestly with 91% still saying that it would be fairly easy or very easy to get alcohol. In 2012 the drop in availability halted in the upper grades. Overall, it appears that states, communities, and parents have been successful in reducing access to alcohol among the younger teens."
