No. 6: Computers and Mathematics. Recent graduates with a degree in computers and mathematics are at an unemployment rate of 8.2%. However, the study found that unemployment in this field varies depending on the major’s technical and scientific content. Jobs will still be available for technical computer specialists who have the ability to write software and create new applications. Unfortunately, specialists who use software to manipulate, mine, and relay information will have a tough time getting a job during a recession. Those who invent computer technology will be in greater demand than those who use computer technology.
