According to the 2013 National Survey on Drug Use and Health nearly 7.3 million 12-20 year old girls reported consuming alcohol in the past year.
In 2013, males and females ages 12 to 20 reported similar rates of past month alcohol consumption (23.0% v. 22.5%, respectively), however, rates of binge drinking (15.8% v. 12.4%) and heavy drinking (4.6% v. 2.7%) were higher among underage males than their underage female peers. Among 12- to 17-year olds, the percentage of males and females who report drinking in the past month (11.2% v. 11.9%, respectively) and binge drinking was relatively the same (6.6% v. 5.8%).

Among college students long-established and large gender differences exist in the prevalence of binge drinking, however this difference has generally been diminishing. According to the 2013 Monitoring the Future Study 43% of college males report having consumed five or more drinks in a row during the previous two weeks compared with 30% of their female peers. This once narrowing gender difference has slowed with male college student binge drinking rates increasing in 2013 and female binge drinking rates declining slightly. Extreme levels of binge drinking rates indicate a significantly larger variance by gender for the combined years of 2005-2013 with male college students more likely to engage in these extreme levels of drinking – 23% of males compared to 7% of female college students reported having 10 or more drinks in a row and 9% of college males and 2% of college females report consuming 15 or more drinks in a row.
