Data from the Office of Personnel Management shows that the percentage of women in the civilian federal work force has been shrinking.
Before Obama took office, it was already smaller than the percentage in the overall national civilian labor force. Under Obama, it has gotten smaller still.
The Office of Personnel Management maintains a database called FedScope that contains historical information going back to 1998 on much of the federal civilian labor force (but excludes, for example, the Judiciary, the White House, the Office of the Vice President, several intelligence agencies and the legislative staff of Congress). According to this database, about 44.4 percent of civilian federal workers were female in 1998.
In 2013, only about 43.5 percent were female — the lowest percentage in the sixteen years available.
