It is important to note that these areas tend to be highly demanding during the degree programs which results in less candidates graduating than jobs in these fields. Whereas the majors in lowest demand tend to be less demanding during the degree programs, therefore producing more graduates than jobs.

In the highest demand majors, one will face more intense demands to complete the degree. In the majors in lowest demand, one may find it more difficult to obtain career-related employment immediately after graduation.
