Overall, the prevalence of college drinking over the past two decades, measured as lifetime, annual, and past 30-day consumption rates have all declined. Since 1991, lifetime consumption among college students has declined 14% proportionately, while annual consumption and monthly consumption are down 10% and 9%, respectively. Despite this long-term progress, over the past ten years trends in college drinking have remained relatively unchanged.
There are also substantial gender differences in alcohol consumption among college students and young adults, with college males drinking more than females. In 2012, four out of ten college males (43%) reported consuming five or more drinks in a row during the previous two weeks compared to one-third of their college female peers (34%).
