这个数据要保留三粒盐

1, Dual, triple majors are not uncommon at some schools, especially private schools. So your data might overstate (i.e., if you sum up percentage of all majors, it will be over 100%)

2, Large Us typically have more programs and less concentration

3, At some schools, computer science and engineering are combined into one program. It is difficult to differentiate CS and computer engineering
