From January to August 2011 (appointments by Mubarak during uprising to appease demands of protesters) there were 20 military governors – constituting 74% of the total governors. From September 2011 through today, there are 14 military governors*, constituting 54% of the total positions.
Some additional notes/caveats:
* Cairo and Alexandria, while they have non-military governors, they do have deputy governors that are military - thus, I have counted them as military governorates as I find it hard to believe that the doctors would trump the say of the military. I could be wrong but that is my assumption for now which is reinforced by the alleged influence General Sayed El-Barie had when he was secretary general of Giza (superseding the governor himself on a decision.
Story worth reading just to see who exactly is being appointed to these positions: When Aswan’s Sayed El-Barie was also Secretary General of Giza – and there is testimony from people at the time that he would only let projects be given to “select” companies - http://today.almasryalyoum.com/article2.aspx?ArticleID=48491&IssueID=588)
The list in "previous governorates" column is nowhere near complete. I was just curious as to whether there would be any cross-over from one appointment to the next and, not surprisingly, there is – and quite a bit of it at that. The governors with previous roles written next to them are simply spot checks, I would guess that all the others have had “civilian” leadership roles in one way or another (deputy governors, secretary generals, etc.)
The New Valley governorate takes up approximately 50% (44% to be exact) of Egypt's landmass - that one is not only headed by a general, but by a (former) member of SCAF (see link)
