Licensed Pilots vs. Drone Operators

The FAA announced that as of February 2016 there were more registered drone operators than there were licensed pilots in the U.S. (325,000 drone operators vs. 320,000 licensed pilots). This might a little misleading because the total number of pilots in the U.S. is said to be 599,086 (student pilots + licensed pilots according to a 2013 statistic).
Of the total number of licensed pilots in the U.S. only 6% (39,621) are female.
