Lots of universities post their career and graduate school placements by major. I can’t seem to find that for Duke. I’ve found their “Duke Career Outcomes Data”, but it is for the school as a whole, and it is not very specific. Is the data I’m looking for available somewhere?
I found the info for the Engineering school, they list it by major: https://pratt.duke.edu/undergrad/admissions/where-students-go
And Trinity, but they list it by discipline:
https://trinity.duke.edu/undergraduate/applicants/career-paths
Something you may also want to consider is return on investment. There are an increasing number of studies that assess long-term value rather than just immediate job placement (example, https://cew.georgetown.edu/cew-reports/collegeroi/).
