The Society for Women engineers has a set of links to the some nice tables compiled by the NSF about various racial distinctions, (African American, Non-white Hispanic, American Indian) and genders in various fields.
The numbers are starker than I'd imagined. The data I finally decided to look at is 5 years old, and if you poke around on the NSF pages, they talk about increases in minorities of various varieties increasing, but it is in single digit/annum rates.
Here are a few numbers. In 2006 number of PhD's in awarded. For the record, accoring to the 2010 census, there are between .9% and 1.1% American Indian/Alaskans in the US (depending on how you count Hawaiian/Pacific Islanders), 15.08% Hispanic/Latino, 12.3% African American.
Total Phd's granted by general field in 2006, and percent female
Underrepresented minorities (as percentage of total):
Female Minorities (as percentage of minority group):
It would seem that once a minority group makes it into academia, the male/female divide seems to disappear. This is a trend I've noticed in other contexts. Maybe I'll ramble about that later.
The big losers? MechE (13.85%), EE(14.86%), Physics(16.56%) for gender inequality.
For Underrepresented minorities, the wall of shame is Astronomy (1.52%), EE(1.88%), Physics (1.9%).
This doesn't cover the whole picture. I'll be keeping an eye out for other pieces of "interesting" data, like who gets hired, over the next few weeks.
*Agricultural, Biological, Aero/Astro/Oceanic, Computer, Math, Physics, Chemistry, Astronomy, Psychology, and Social sciences.
** Dropping Psychology, and Social science, where women are overrepresented, this becomes 35.84% Not great, but respectable.
