NSF surveyed Science and Engineering graduates and provide some not too surprising results in: What Do People Do After Earning an S&E.

Most graduates use the science and engineering knowledge (even if they went on to get unrelated post-graduate degrees in say business, law or no post graduate degree). It seems approximately 20% report having managerial positions currently (excepting recent graduates who are less likely to be managers).

Frankly I find this information less interesting than: the continuing high pay of engineering graduates and the fact that the top undergraduate degree for S&P 500 CEOs is Engineering. It would be interesting to see salary rates (with lifetime earnings), unemployment rates and career satisfaction by undergraduate degree (compared to other undergraduate degrees) throughout their careers (NSF’s Science and Engineering Indicators - Workforce does include very interesting information along these lines).
