If 14% of the PhDs employed by the U.S. Government was 10,109, then there were about 72,207 total. That's about 3.2% of the civilian government, compared to 2.1% in the public workforce (and 1.3% of population).

So, the government tends to employ PhDs at a substantially higher (~50%) rate than the public workforce.

Edit: Yeah, oops, people generally use public / private the other way around.
