Between 2001 and 2010 the percentage of girls under 15 who have been drunk rose to 41 percent from 26 percent in the U.S., according to a study by the Organization of Economic Cooperation and Development (OECD).
The study also found that the percentage of under-15 boys that had been drunk was 43 percent in the 2010 results. It had been just 30 percent in 2001. The OECD uses the data to recommend tax increases on alcohol, finding that instances of binge-drinking and youth-drinking decrease in countries where alcohol costs more.
