<p>A few schools survey their graduates in various majors about how much they are earning at their first jobs, or if they are unemployed, or in graduate school.</p>

<p>Be careful, though, since economic and industry cycles can have a big effect. Computer science is good now, but it was not in the early 2000s (tech bubble crash). Civil engineering was good in the mid 2000s (construction / real estate boom) but not in 2009 and 2010 (construction / real estate bubble crash). On the other hand, some majors seem to do poorly on the pay scale all the time (e.g. biology and humanities), so someone majoring in such a subject needs to be very careful about keeping debt low.</p>
