One of the comments to the article makes the very valid point no control for sex is done, and Math/CompSci/Engineering degrees are much more male dominated. Could this also be expanded to location? Salaries in high cost locations tend to be higher. Salaries, over 1 or 20 years, are not the same thing as take-home net of living and property costs. Are Math/CompSci/Engineering employment paths located in higher cost locations? I don't know, but they could be.
