One in four American college students is over 30 years old, part of a graying student population that is offsetting a sharp drop in the number of traditional-age college students, according to a Census Bureau report released yesterday.
Of the 13.2 million students enrolled at the nation's colleges and universities in 1989, about 40 percent were age 25 or older. The traditional 18-to-24-year-old group comprises about 60 percent of the student population. In the '70s, that group made up 75 percent.
