Increasing numbers of college students in the United States are accumulating more than one major, with an estimated 25% of college graduates with more than one major.[4][5][6] Some schools report that 30% to 40% of their undergraduates are double majors.[7][8] A number of factors are thought to contribute to this increase, including greater numbers of students entering college with AP credits and the belief that a second major gives a student an edge in the job market.
