This closely jives with the "Degrees conferred by sex and race" stats from U.S. Department of Education Institute of Education Sciences National Center for Education Statistics.
ps. Interesting side note, is that while looking this up, I wanted to see if H1B visas skewed the stats. I found a page that lists "10 of the largest and hottest US Companies that hire skilled immigrants for H1B visas" [2]. What's interesting is that these numbers are far lower than I thought they would be, as in, I thought H1B visas were the life blood of these companies. But these numbers are probably not even a fraction of their total employee base.
Amazon 333 visas
Apple 520 visas
Facebook 173 visas
Google 685 visas
Microsoft 2,125 visas
