Those are some pretty strange groupings. I suppose they're counting Economics and Finance degrees as business? I'm also pretty surprised about the amount of social sciences/history degrees that are being pursued. What exactly were these people planning to do? Certainly explains the law school problem.
The "law school problem" is that there's too many law students and not enough jobs. People are increasingly using law school as their "I don't know what to do with my life" card, whereas those people used to just get a business administration degree and trip into some element of the corporate ladder after undergraduate studies.
The "problem" is that they're incurring another $80k of debt for another degree that doesn't make them particularly useful to anyone.
So much for encouraging people to get college degrees. If they all end up getting the same degree and flooding the market, what was the point? I hoped that the growth would be spread out between many fields, but everyone just piling in and getting business degrees doesn't help.
http://nces.ed.gov/programs/digest/ is the original report where the numbers were compiled. It seems like 2009 was the last report and that 2007-2008 academic year is the latest data available that the report used when dealing with degrees conferred.
