The age group reported for female collegians as having "increased dramatically" would be grad students.
Since you "wonder" about "other factors", the missing data may be helpful in making a determination and/or providing an opinion.
Well, 21 year olds and 22 year olds are usually are usually in their 3rd year and 4th year, respectively, of their undergraduate study. And the 23 year olds are those who are so stupid they drank themselves retarded while in college and forced daddy to pay for an additional year. As to the idea there has been a rise in binge drinking over the past 20 some years I do not know. However, it is undeniable that there is a culture amoungst college kids of drinking.
